United States and Argentina, and trade ofÀces in Chile, Mexico, Germany, The Arab Emirates, South Africa and China,
the company maintains a trained team to meet the needs of
customers located throughout more than 70 countries on Àve
continents where the company is present. Fras-le is a Randon
Group company.
High Technology
Fras-le has the largest and best equipped lab in Latin
America to test its products, which are then delivered to
test Àelds, race courses and roads, where they are approved and released for production. The entire process is
followed up by Fras-le`s and OEM companies` engineers to
ensure that the Ànal product complies with the required
speciÀcations.
Research Lab
The Chemical Research Lab is in charge of analyzing the
raw-materials for the development of new products and
the improvement of existent material. At Fras-le, more
than 135 different types of raw-materials are used in the
production line. SpeciÀc methods of analysis are employed
in new alternative raw-materials until coming to the
compounds that make up the products.
Quality Assured by Raw-Materials
The raw-materials lab is responsible for analyzing over
135 different types of raw-materials accepted into the
company. It also supports production system processes and
develops new suppliers. These are the most important tasks
carried out by the raw-materials lab, which also develops,
certiÀes and audits the processes used by the suppliers in
order to maintain their already proven qualiÀcation levels
as Fras-le`s suppliers. The lab plays a very important role
for Fras-le to gain market share, as it assures the quality
of its products. This means that the raw-materials, the
productive process and the tests are crucial for the safety
of the products in any of their applications.
Technical Manual- LIGHT VEHICLE - 4
Assessment
All products being developed and those in the production
lines are tested in the Physical Lab, which integrates
the Research and Development Center. Different pieces
of equipment simulate real working conditions of rawmaterials in their different applications, being instrumental
in the improvement of the products until they reach the
Ànal quality required by consumers.
The lab operates in three working shifts, continually
running tests and assessing their results. The lab includes
the entire process of Fras-le`s products, from development
to assessment of the products in the market, from the
initial tests to the Ànal user through speciÀc tests.
More than 120 different types of trials are carried
out monthly in this Research and Development Center
which offers the most complete testing structure in Latin
America.
In Pilot Production, Quality is Assured.
In the Pilot Lab, samples are produced from customers`
new needs and requests, especially OEM companies of
vehicles. Experiments with new formulations are carried
out. If approved, they go through all test phases until they
reach the regular production lines. The Pilot Lab controls all
features associated to the development of these products.
At the beginning, Fras-le has not only absorbed technology
from well-known manufacturers of friction materials in the
world, both European and North-American , but has also
improved the global production modus operandi. Stateof-the-art equipment and the company’s own culture
and experience are the basic ingredients of Fras-le`s
philosophy: that of developing high quality products that
reÁect the tradition of its brand in the market. In addition
to developing its own technology, Fras-le also maintains
agreements and partnerships
Motion Control: Fras-le`s Mission
In addition to research, development of materials and
products, test Àelds are also very important to maintain
quality levels. During tests, products applied to vehicles go
through all situations they will possibly face when operating
in real situations, on the most diversiÀed road conditions.
The performance of the products is also strictly followedup by technicians who visit customers on a permanent
basis. These technicians give lectures, courses and instruct
retailers` clerks, mechanics and drivers so that they can use
the products safely.

FRICTION MATERIALS FEATURES
Mechanical Strength
Friction material must have a mechanical strength
sufÀcient to stand the efforts inherent to the application
it is designed for. Among mechanical efforts, we highlight
Compression (rubbing against the friction surfaces) and
Shearing (which results from tangential forces caused by
rotation movements).

COEFFICIENT OF FRICTION
The coefÀcient of friction is the most important factor
in friction materials. Its value must be kept constant within
a certain temperature range.
A high coefÀcient of friction does not necessarily mean
quality in friction materials. Using the brake too hard
is sometimes as dangerous as lack of brake. The friction
stability is a crucial factor that depends on temperature,
speed, pressure and external factors. Lack of brake is not
necessarily caused by the friction material, but may be
caused by a failure in the hydraulic or air system.
Please see below the most important features involving
friction materials:
Durability
The useful life of friction materials is a very important
factor that depends on the quality of the friction material
selected for a certain application. One of the factors that
determines the durability of friction materials is temperature.
Friction materials are bonded by organic resins that
impose limitations on their working temperature. If the
brakes or clutches are constantly used in high temperatures,
wear on friction materials accelerates. Durability is
also affected by the geometry of the brake and clutch,
cast material and Ànish of the braking surfaces. A good
quality friction material must be also a thermal insulator
to protect the deepest parts from the high temperatures
generated during brake and cluck applications. Wear
on friction materials is necessary to renew the friction
surface, otherwise glazing may occur. On the other
hand, this renewal should not happen too quickly, at
the risk of affecting the durability of friction materials.
Sometimes,
complaints
about
durability
are
due to problems related to the dimension of the
brake ( if the drum heats too much, the working
conditions have not been
properly designed).

STOPPING DISTANCE
Basic Concepts in Brakes
People react differently to obstacles or to diverse
situations on trafÀc. When they are walking on roads, they
may react differently and unexpectedly from when they
are walking on streets. Therefore, it is necessary to get
familiarized with the driver`s behavior when driving on
different roads.
Braking a vehicle basically depends on three factors:
the vehicle, the road and the driver. A higher or lower
braking efÀciency basically depends on the combination of
these three factors.
Please see below a table that shows stopping distances
in relation to the vehicle’s speed:

Braking Force:
force resulting from the brake
mechanism contrary to the motion of the vehicle. The
higher the compression, the higher the braking force.
Fuerza de Frenada:
THE BRAKE AND
THE PHYSICS
An hydraulic brake works based on the Pascal`s law.
“ Pressure applied to a conÀned Áuid is transmitted
undiminished throughout the conÀning vessel of the
system”.
Example: By using an injection syringe (conÀning vessel),
we can clearly exemplify the law: let`s block the outlet
hole and press the piston. There will be pressure at all
contact points of the liquid.
Es la fuerza resultante del
mecanismo de freno en sentido contrario al movimiento
del vehículo. Cuanto mayor la compresión, mayor la fuerza
de la frenada.
Fade: reduction in stopping power (i.e. the reduction of
friction between the brake pad /brake linings) caused by a
buildup of heat in the braking surfaces.
Technical Manual- LIGHT VEHICLE - 7
Considerations on Brakes
The Equipment
The Brake Stops the Wheel and the Ground
Stops the Vehicle: A vehicle in motion means that
Master Cylinder:
the wheels are turning. Brakes are not designed to stop
the vehicle, but slow down the wheels rotation until they
stop completely. Assuming a vehicle has brakes functioning
perfectly but the tires are poor and the road is wet: after
applying the brakes, we guarantee that the wheels will
stop, but we cannot guarantee that the vehicle will stop
together with the wheels.
The master cylinder activates and controls the braking
process. When applying the brake pedal, the piston
compresses the Áuid in the compression chamber, building
up pressure throughout the hydraulic circuit of the system
( Àg. 02).
Brakes Are a Set: Therefore, we should treat them
as such. Their performance depends on the performance of
their parts taken as whole.
Brakes Are a Safety Item: If a vehicle’s component
breaks while in motion, you still can manage to stop the
vehicle, but if there is a brake failure, the vehicle will
stop through collision.
Friction X Brake:
Whenever a body tries to slide
over another one, a force called FRICTION prevents it from
sliding.
Àg. 02
Wheel Cylinder
When you apply the brakes, the Áuid compresses the
pistons, which push the brake shoes against the drum (
Àgure 3).
Sliding = Heat: If we slide down a rope, our hands will
burn, but if we go down normally (not sliding) our hands
will not burn.
Gases X Compressibility: an inÁated tire suffers
deformations against weight exerted on it, that is, gases
ARE COMPRESSIBLE.
Liquids X Compressibility:
If we completely inÁate a tire with water under
pressure, the result will be a rigid tire that will not suffer
deformations when weight is exerted on it. This means
liquids ARE NOT COMPRESSIBLE.
Good performance of the brake system depends
on preventive maintenance. Carry out preventive
maintenance every six months and your brakes will always
work properly.
Àg. 03
Brake Caliper
Component that needs a disc that, when grasped,
enables the piston to press the pads against the disc,
causing friction.
Servo-Brake
Equipment designed to provide more comfort to the
driver when applying the brake pedal. The servo-brake
uses atmospheric pressure that, combined with the vacuum
generated by the engine, increases the force exerted on
the pedal.
Brake Disc
Metallic part with a Áat and parallel surface that resists
to the compression of the pads exerted by the hydraulic
system.

BRAKE SYSTEMS
Advantages of Disc Brakes:
Hydraulic Brake
Distributes the force by means of pressure in a Áuid
and acts on the brake shoes by means of pistons ( Àg. 4).
Wheel cylinder
Brake Lining
Drum
Self-adjustable, Áat braking surface, higher cooling and
cleanliness, easy maintenance, and uniform braking even
in abrupt braking actions.
Due to these advantages, there has been a trend to
replace drum brake systems by disc brake systems in all
vehicles ( including the heavy line vehicles). For this to
be fully implemented, pad materials should be developed
to stand high temperatures, as their braking area is small.
Studies have also been carried out to improve their thermal
conductibility (fan), good mechanical resistance and high
resistant to friction, thermal fatigue, and corrosion.

Disc Brake
In this brake, the braking force is obtained by pressing
two brake pads against the brake disc. The disc must be
submitted to equal forces on both lateral faces so the disc
and the pads may wear equally (Àg. 05). There are two
versions of disc brakes: with Àxed caliper (Àgure 06) and
two pistons; and the Áoating type ( Àgure 07) with one
piston only. In the two-piston type, each piston activates
one brake pad against the disc face. For being less cooled
by the movement of the vehicle, the piston located on the
wheel side dissipates the heat generated during braking
action through the caliper body and the brake Áuid. As
heat dissipation is lower in this type of construction, a
Áuid proper for high temperatures must be used with this
brake.

DISC BRAKE PADS REPLACEMENT
When replacing disc brake pads, we recommend that
you follow the procedure below ( Fig. 08):
5º) Replace the pads and check the condition of the
springs. If necessary, replace the springs;
6º) We recommend that you use brake Áuid proper for
operation in high temperatures;
7º) Once you complete the procedure, check the brake
pressure;
8º) Apply the brakes 6 to 8 times from 60 km/h up to
40 km/h and apply the brakes again 6 to 8 times from 40
km/h until the vehicle comes to a complete halt. This will
allow pre-burnishing to take place. We remind you that a
satisfactory output of the material depends on its initial
behavior;
9º) Soon after replacing the pads, use the brakes
moderately. This will allow a perfect burnishing between
the friction material and the brake disc.
1º) Clean the disc, mainly the friction surfaces. If
necessary, grind both faces simultaneously so they can
have parallel faces. Remove any particles of carbon dust
left by the machining process with industrial alcohol;
2º) Clean the brake caliper where the pads are with a
steel brush;
3º) With a proper tool, move the piston away from the
set by Àrst opening the bleeding screws. This will allow
the pads to be introduced easily. Do not use poor quality
pads;
4º) In case the pistons are gripped, replace the caliper
repair kits;

BRAKE FLUID
To keep the brake Áuid in good conditions, never
complete the level of the reservoir. If Áuid level is low,
check the cause, which may be leak or excessive wear on
the pads. If you complete the level, good Áuid will mix
with a contaminated Áuid, changing its properties and
not offering the ideal working conditions. Contamination
of the Áuid by humidity ( water) will not only cause the
brakes to operate in higher temperatures for a longer
time ( wearing down the pads more rapidly) but will also
damage the metallic parts of the system, which, in contact
with humidity, will cause corrosion, compromising the
efÀciency of the system.
Technical Manual- LIGHT VEHICLE - 10
GRINDING DISCS
The friction surfaces of brake discs affect directly
the useful life of the pads. Cracks, thermal Àssures and
grooves must be removed by grinding these surfaces
whenever you feel they need (use your hands to feel
it). On the other hand, grind brake discs only as far as
the safety limit recommended by manufacturers. We
recommend that you replace them whenever the actual
thickness of the disc is equal or lower than the dimension
engraved on the disc.

ABS SYSTEM
In addition to all traditional brake components, the
vehicle may also be equipped with the ABS system, which
offers many advantages to the driver in terms of safety.
Anti-Locking Braking System (ABS) is designed to
prevent the wheels from locking while braking, due to
heavy braking, in any braking condition, ground or tire,
especially on slippery surfaces. The system allows lateral
friction to be maintained on the wheels being decelerated,
even during the total application of the brakes. As a result,
the stability and steering condition of the vehicle are
guaranteed within physical limits. When braking friction
occurs between the tire and the ground, the deceleration
of the vehicle and the stopping distance are optimized.
An anti-locking braking system is a re-feeding system
that controls the braking pressure in response to the
average deceleration of the vehicle to prevent the wheels
from locking. The system basically consists of the following
parts:
- Wheel speed sensor: captures the variation of wheel
rotation and sends a signal to the controller;
- Control Unit: receives the signal from the sensor,
interprets it and sends the decision to the modulator;
- Modulator: controls the brake pressure as a result of
the signals received.
Brakes equipped with ABS do not require special friction
materials. The original or regular friction material can be
used.
The wheel rotation sensors inform the control unit if
there will be a locking action at one or more wheels. The
control unit (modulator) will stop such a locking by giving a
set of signals to the hydraulic control, which will regulate
the brake oil pressure individually, in each wheel.
This way, the driver can brake the vehicle heavily
without locking the wheels, maintaining steering control
with ease and safety at the shortest distance traveled.
The ABS system also allows the driver to hit the brakes
fully on curves at high speeds, even on wet or slippery
roads without the fear of skidding or loss of control.

mean they are the only possible causes. For each cause a
solution is presented.
Engaged hydraulic system pistons.
Poor quality brake linings and pads.
Brake linings and pads contaminated
with grease or oil.
Overheated brake linings and pads (brakes
are applied repeatedly and continually).
Brake linings and pads not burnished.
Glazed brake linings and pads.
Moldy brake linings.
Replace the brake linings or brake pads
Friction materials ( brake linings and pads) are responsible for decelerating the wheels. Therefore, any damage or
irregularity in the friction material affects directly the stopping distance. When the brake drum is not well adjusted,
pressurization takes place slowly, the brake pedal has a longer run and it is difÀcult to stop the vehicle. In this case,
adjust the brakes correctly. Lack of pressurization or difÀculty to pressurize the brakes on the wheels may have different
causes as well.
NOTE: Excessive load or passengers will require a greater effort from both, the driver and the brake system, not
allowing for a safe braking action at a shorter stopping distance.
PROBLEM
BRAKE PEDAL
TREPIDATION
CAUSE
Brake discs with non-parallel friction surfaces. This
happens due to poor grinding or poor quality of the
discs.
Out-of-shape brake drum.
Misalignment during rectiÀcation.
SOLUTION
Grind correctly or replace the discs.
Grind again or replace the brake drum.
This usually happens when the brake Áuid is forced to return to the brake pump due to problems in the wheel
brakes.
PROBLEM
CAUSE
SOLUTION
Adjust well the brake-servo inlet rod.
VEHICLE WITH
BLOCKED
WHEELS.
Inlet rod of servo-brake is improperly adjusted.
Inlet rod adjusting screw, which activates
the master cylinder, is not adjusted.
Brake hose is damaged, making pressure relief more
difÀcult in the brakes.
Regulate the adjusting screw.
Replace the defective brake hoses.
This happens when the wheels are overheated or when the wheels do not turn when the vehicle is suspended.
Technical Manual- LIGHT VEHICLE - 14
PROBLEM
CAUSE
Too much play between the pedal brake lever and
the servo-brake inlet rod, or between the outlet rod
( servo) and the master cylinder.
Air in the hydraulic circuit
Internal or external leak somewhere in the circuit.
Overheated brake disc.
Old Áexible hoses or of poor quality. They do not
stand the pressure and get swelled.
PEDAL GOES TOO
Drum
with
internal diameter out of speciÀcation
DEEP DOWN
(many times ground) with too thin walls. They do not
stand the brake shoes force and may break.
Non-burnished brake linings and pads, since there is
a signiÀcant loss of contact area between the friction
material and the friction surface of the disc or drum.
Automatic adjusting mechanism of the brake is engaged, leaving the brake linings far from the drum.
Poor quality Áuid or contaminated with water. The
Áuid vaporizes too easily, generating gases in the
circuit.
SOLUTION
Correct the play in the rods.
Bleed the brake system.
Internal leak: Replace the internal repair kip when the brake caliper does
not show signs of internal corrosion, otherwise, replace the hydraulic assy.
External leak: locate the leak and replace the defective components.
Avoid using the brake too much.
Replace the Áexible hoses.
Replace the brake drum.
A perfect burnishing of the friction material takes place at the extent the
brakes are used (alter approximately 500 km (in the city).
Repair and lubricate the automatic adjusting mechanism.
Change all the brake Áuid.
To engage the brakes, the pedal must go to a certain point. This varies according to the vehicle and to each
manufacturer’s speciÀcations. If the brake needs to go too deep down, it is a sign that there are problems.
PROBLEM
CAUSE
THE VEHICLE
PULLS TO ONE
SIDE
Unequal adjustment of the drum brakes in the front
axle.
During replacement of brake linings and pads, make
sure not to contaminate them with grease or oil, as
this causes imbalanced braking actions.
Discs or drums with wrong diameter / thickness.
Non-matching brake linings and pads ( different
types).
The hydraulic pressure does not reach one of the
brake sides due to an obstruction in
the piping or Áexible hoses.
Wheel cylinder or disc brake caliper
is engaged in one of the sides.
Brake retaining springs with pressure loss in one of
the sides.
SOLUTION
Adjust the drum brake.
Replace the contaminated component.
Grind or replace the disc or drum.
Use the correct part during replacement.
Unclog the piping or Áexible hoses, replacing the damaged parts.
Replace the internal repair kit when the brake caliper does not show signs of
internal corrosion, otherwise replace the hydraulic assy.
Replace the springs.
Any difference between the left and the right side in the front axle, whether in the suspension or brakes, results
in the vehicle pulling to one side.. The Àrst measure to avoid this problem is servicing the brakes in each axle, making
sure to keep the same conditions in both sides.
Watch the following factors, as they may contribute to the defect and are not part of the brake system:
-Badly calibrated tires or of different types;
-Irregular steering system ( convergence or Caster angle out of speciÀcation);
-Bearings of front wheel hub are damaged or loose;
-Front suspension or steering bar are loose or damaged.
Technical Manual- LIGHT VEHICLE - 15
PROBLEM
CAUSE
Locked master (cylinder oxidation).
THE BRAKE
PEDAL IS TOO
HARD.
Brake linings and pads are glazed or of poor quality.
Engaged pedal articulation, causing
the pedal to get too hard.
Kinked brake lines.
Obstructed brake hoses.
Locked wheel cylinder or brake caliper.
Damaged servo brake.
SOLUTION
Replace the internal repair kit when the brake caliper does not show signs of
internal oxidation, otherwise replace the hydraulic assy.
Replace the brake linings and pads.
Disengage the pedal articulation.
Open them and replace the damaged components.
Replace the brake hose.
Replace the internal repair kit when the brake caliper does not show signs of
internal oxidation, otherwise replace the hydraulic assy.
Repair or replace the brake servo.
Problems in the servo brake require greater effort to apply the brakes, since there is leak in the servo and the hoses
or air inlet Àlters are obstructed. Under any of these conditions, the system does not work, causing too much effort at
the pedal. Despite this, the brakes are still working.
PROBLEM
CAUSE
VEHICLE WITH
LOCKED WHEEL
Disc brake retaining ring is dry. This prevents the
piston from returning.
Improperly adjusted brake shoes or
parking brake cable.
Out-of-shape drum.
Drum brake springs show fatigue or are broken.
Damaged return valve in the power brake booster.
SOLUTION
Replace the repair kit of the disc brake caliper.
Adjust the brake properly.
Grind or replace the brake drum.
Replace the springs.
Replace the return valve.
This happens when the wheels are overheated or when the wheels do not turn when the vehicle is suspended.
PROBLEM
CAUSE
SOLUTION
Replace the brake linings or brake discs.
Check if there is play or damaged pieces. Replace if necessary.
NOYSE BRAKES
Glazed brake linings, worn discs or of poor quality
Play or wear.
Loose, wet, out-of-center or
contaminated brake linings.
Improperly assembled brake shoes or brake linings.
Improperly-adjusted springs or showing fatigue.
Replace the pads or linings.
Assemble the linings correctly.
Replace the drum brake springs.
This usually happens when the brake pads or linings are glazed, or when they are contaminated. Discs and drums in
poor conditions also may cause noise.
PROBLEM
CAUSE
ABRUPT
BRAKING
ACTIONS
Defective internal mechanism of the
servo-brake.
Brake linings or pads with coefÀcient of
friction higher that the one designed for
the vehicle.
SOLUTION
Repair or replace the servo brake.
Replace the brake linings or pads.
Brakes are designed to carry out safe and comfortable braking actions. When applying the brakes, the effect should
not be aggressive.
Technical Manual- LIGHT VEHICLE - 16
TIPS ON STEERING PROBLEMS
Brake Pedal:
: the pedal travel should not be longer
than 5,0 cm or 2,5 cm in vehicles equipped with servo
brake. When the pedal is too low or there is no resistance,
the hydraulic circuit may be defective or bubbles may
be building up in the system. If the pedal gets too hard /
heavy, this means the servo brake must not be working for
some reason.
With the engine on, put your foot on the brake with medium
force for 15 seconds: if the pedal does not move, the brake
is in good conditions.
Whenever You Replace Brake Linings or
Pads: Grind the discs or drums or have them replaced.
This will allow for a better burnishing, improving the
efÀciency of the braking actions, increasing the useful life
of the linings and pads, and eliminating noises.
Wheel cylinder
Brake Lining
Glazed Brake Pads:
if there is overheating in the
system in the beginning of the pads` useful life, glazing
may occur. This can be usually avoided with the preburnishing between brake pads and disc, or through a
thorough maintenance in the system. Every 5,000 km,
check the brake pads and inspect the brake system every
10,000 km. The minimum thickness should be 2 mm in the
brake pads and 0,5 mm in the brake linings at the upper
edge of the rivets.
Drum
Brake Shoe
If the Front Wheels Lock: the vehicle continues
running but loses steering control. Some of the causes
may be: rear brake linings and pads improperly assembled,
worn or with oil; improperly adjusted slack adjuster;
worn or defective disc or drum and problems in the rear
hydraulic circuit.
If the Rear Wheels Lock: the vehicle loses stability
Brake Fluid:
For being hygroscopic, the brake Áuid
absorbs water in the hydraulic system, especially when it
is submitted to great efforts. Down hill and heavy trafÀc,
for example, are situations that generally overheat the
brakes, increasing the temperature to over 150° C. This
may cause air bubbles to build up in the brake system,
generating brakes failure and leading the driver to hit the
pedal in vain.
The brake Áuid must be changed according to the
manufacturer’s instructions.
and may slip. Some of the causes may be improperlyinstalled front pads, worn front pads, or even a defect in
the support of the front axle.
Stability and Skidding:
the vehicle should keep
on course after a braking action. If it does not do that,
there must be a failure in one of the sides of the brake
system: stuck cylinder pistons, defective or worn discs,
wrong brake pads, worn pads, contaminated with oil or
glazed.
Technical Manual- LIGHT VEHICLE - 17
INSTRUCTIONS TO BOND FRICTION MATERIALS
TO METALLIC SURFACES
Bonding friction materials on their metallic supports
requires a few cares.
The metallic surfaces that will contact the friction
materials must be free from any type of contamination.
Whenever it is possible, sandblast the surface or use any
other process to remove impurities without damaging the
surface.
A number of adhesives can be found on the market.
Follow the manufacturer’s instructions concerning bonding
and its application / curing processes.
As an example, please see below an extract on the
application of one type of bonding material:
EC 1099 Adhesive - 3M:
Application Process:
Remove any type of residue / impurity from the brake
shoe surface – where the brake lining will be installed.
Clean the brake shoe surfaces with alcohol or acetone.
Apply a uniform coat of adhesive on both, the brake
shoes and the brake linings, and wait for three minutes.
Position correctly the brake lining onto the brake shoe
by placing the set in a proper device that will keep the
brake lining pressed against the brake shoe. Take the set
to a pre-heated oven (150° C ( ± 5)) and keep it there for
about four ( 4) hours. Remove the set from the oven, allow
it to cool and remove possible surplus of adhesive from the
sides.
The information above must be updated according to
the adhesive manufacturer’s instructions.
