Braking compensator

Carry out the same operation on the other circuit:
- one at the front left hand side,
- one at the rear right hand side.
If there is a large difference (values exceed
tolerance ranges), replace the compensator since
no repair is permitted.ADJUSTMENT
The method for adjusting the compensators used
today in After Sales is simple and only involves
using two pressure gauges which must be
connected to the braking circuit (front right
wheel and rear left wheel, then front left wheel
and rear right wheel).
Checking and adjustment is carried out with the
vehicle unladen, the fuel tank full and the driver
on board.
After imposing a certain pressure at the front by
pressing the brake pedal, just read off the
pressure at the rear and compare the value with
that given in section 07. Then move the
compensator rod by releasing the bolt ( 1 ), so rod
( 2 ) may be adjusted.
NOTE : do not alter the position of nut (3).
This method is difficult to carry out when the
vehicle is loaded, as is often the case for a utility
vehicle fitted out with shelves full of spare parts
and tools.
The special case of utility vehicles has led to the
development of a different method for
adjustment which uses a deflection calculation
(index of crushing) for the tyres (this is
inexpensive but must be carried out with care).
The graphs for rear pressure as a function of tyre
deflection must be consulted.
