TOOLS
- Braking pressure checking tool : 4140-T
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.
