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.
- Checks are done between the following compo-
nents :
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 pressure
(without ever releasing the pressure to adjust it).
- 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.
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.
