CHECKS AND ADJUSTMENTS : BRAKE COMPENSATOR

XSARA - All Types

To perform any checks, it is necessary to calculate the weight on the rear axle in order to refer to the adjustment graphs.

Preliminary pre-check operations.

Calculate :

1) The rear weight of the vehicle (empty tank + 1 person)

2) The weight of fuel in the fuel tank

# Note the vehicle type

# Note the fuel level

Refer to table N° 1

Refer to table N° 2

Refer to table N° 3

3) The weight of options fitted to the vehicle

# Note the vehicle options

4) Add these three weights together to obtain the TOTAL REAR VEHICLE WEIGHT; remove all objects from the vehicle totalling more than

10 kg in weight.

5) Select the adjustment graph that corresponds to the vehicle model. (Refer to tableN° 4).

6) Check the brake pressure.

7) Adjust the load sensitive brake compensator if necessary.

Exemple

- The rear weight of the vehicle (empty tank + 1 person)

- The weight of fuel in the fuel tank (tank 1/2 full)

- The weight of options fitted to the vehicle (sun roof)

- Total rear vehicle weight

CHECKING THE BRAKE PRESSURE

WARNING : Do not touch the plastic nut (1).

PRELIMINARY OPERATIONS

- Place the vehicle on a 4-column lift if possible.

- Fit tool 4140-T.

- Calculate the rear vehicle weight (see tables on preceding pages).

- Check that no hydraulic fluid is leaking and that the pipes are not being obstructed.

- Refer to the graph which corresponds to the vehicle type (see preceding pages).

CHECKS

- Perform the checks between the wheels as follows : front left and rear right - front right and rear left.

- With the engine running, increase the pressure at the rear to obtain a front pressure of 60 Bars.

ESSENTIAL : The checking pressure must be obtained by progressively increasing the pressure (never

reduce the pressure to adjust it).

- Check the increased measurement against the graph. (If the measurement is not within the limits, adjust the

compensator) (see following page).

- To check that the compensator works correctly, increase the rear pressure to 100 bars. (If the measurement is

not within the limits, replace the compensator).

- Bleed the brake system and carry out a road test.

ADJUSTING THE COMPENSATOR

WARNING : Do not touch the plastic nut (1).

IMPORTANT : When loosening the nut (2), the spring (3) may suddenly force off the nut (2) and lock nut (4)

assembly. Calculate the spring length (3) before loosening the nut (2), and use a spanner to hold the lock-nut (4)

in place, thus restraining the spring.

- Loosen the nut (2) while ensuring the lock-nut (4) is held firmly in place.

- Adjust the length of the spring (3) :

- Reduce the spring length (3) to increase brake pressure.

- Increase the spring length (3) to reduce brake pressure.

- Tighten the nut (2) to 1.5 m.daN.

- Check the brake pressure.

Checking procedure

Determining the rear weight of the vehicle

Determine the weight on the rear axle and then refer to the adjustment

graphs.

The allocation table enables you to choose which graph to use for

each type of vehicle.

Refer to the tables of different weights.

To obtain the rear weight of the vehicle, add the following weights :

- Rear weight of the vehicle (tank empty + 1 person).

- Weight of fuel in the fuel tank.

Connect the tool [1] in order to check the rear pressure values relati-

ve to the front pressures (60 and 100 bars).

- Weight of the options on the vehicle.

Remove from the vehicle any object weighing more than 1 Kg.

Rear weight of the vehicle (tank empty + 1 person)

Note the vehicle type.

Consult the correspondence table.

Weight of fuel in the fuel tank

Note the level of fuel in the vehicle and from this deduce the weight

according to the table.

CHECKING AND ADJUSTING THE LOAD-SENSITIVE BRAKE COMPENSATOR

Checking the braking pressure

Preliminary operations :

- The vehicle should be placed on all 4 wheels,

preferably on a lift.

- The tool [1] (in good working order) in place.

- Rear weight of the vehicle determined.

- Check there are no hydraulic leaks.

- Check the absence of pinching on the pipes.

- Refer to the graph corresponding to the vehicle

engine version.

- Compare the value noted with the graph.

- If the value is outside the tolerance, adjust the

compensator.

- In order to check that the compensator is working

properly, note the rear pressure when the front

pressure is 100 ± 3 Bars.

- If the value is outside the tolerance, replace the

compensator.

- Checks are done between the following compo-

nents :

NOTE : Any large discrepancy between the two cir-

cuits will mean that the braking compensator

should be replaced.

- After completing these operations, bleed the bra-

king circuit (see corresponding operation).

- Carry out a road test.

Front LH wheel and rear RH wheel.

Front RH wheel and rear LH wheel..

- On the vehicle, engine running, note the rear

pressure when the front pressure is 60 ± 3 Bars.

ESSENTIAL : The control pressure should be

obtained by progressively increasing the pres-

sure (without ever releasing the pressure to

adjust it).
