Attention! We carry out work with an assistant on a viewing ditch or lift.
Remove the protective cover of the pressure regulator.
When you press the brake pedal with a force of 70-80 kgf..
... we observe the movement of the protruding part of the regulator piston relative to its body.
If the piston moves by 0.5–0.9 mm, twisting the torsion lever, then the pressure regulator is operational. If the piston remains stationary when the brake pedal is pressed, the pressure regulator is defective and should be replaced with a new one.
Adjustment of the drive of the rear brake pressure regulator is necessary when loosening the bolts of its fastening, as well as after any work related to the removal of the rear axle beam, replacement of springs and shock absorbers of the rear suspension.
To adjust, we hang out the rear axle of the car and remove the protective cover of the regulator.
Two keys «on 10» unscrew the nut of the bolt securing the tip of the regulator lever to the rod of the rear axle bracket.
We take out the bolt.
We take out the tip of the lever from the eye of the thrust.
key «at 13» loosen the bolts securing the regulator to the bracket.
We rest the end of the ruler on the floor of the body. Raising or lowering the end of the lever, set it at a distance of 135±5 mm from the side member of the body. Wherein,…
... by moving the regulator on the bolts relative to the slot of the bracket,..
... we achieve light contact of the protruding part of the piston with the end of the lever. Holding the regulator in this position, tighten the bolts of its fastening. We assemble in the reverse order.
With the correct adjustment of the drive of the rear brake pressure regulator, the blocking of the rear wheels during braking should occur somewhat later than the front ones (when braking from a speed of 30–40 km/h).
