Adjustment of the regulator is necessary after replacing the rear springs or the rear axle, as well as during the operation of the car
Put the equipped car on a flat horizontal surface
Using a 17 wrench, loosen the adjusting bolt locknut
We unscrew the adjusting bolt with a 10 key for two or three turns
We tighten the adjusting bolt until it touches the piston shank, after which we tighten the bolt by four more faces of the bolt head
Tighten the locknut with a 17 wrench while holding the adjusting bolt with a 10 wrench
Checking the correctness of the adjustment by observing the side of a sharply braking car
With a good regulator and correct adjustment, there should be some advance in blocking the front wheels relative to the rear
If there is no advance, we unscrew the adjusting bolt of the regulator by two edges and repeat the check of the wheel lock when the car is moving.
The pressure regulator housing has a control hole closed with a rubber plug.
The leakage of the working fluid from under this plug indicates the loss of tightness of the sealing elements inside the regulator.
In this case, replace the regulator assembly.
To replace the regulator, drain the brake fluid
We unscrew the fittings of the three brake pipes with a 12 wrench and disconnect them from the regulator
We unscrew the two bolts securing the regulator to the bracket and remove the regulator
If it is necessary to replace the levers, hold the bolt of the lever strut to the rear axle bracket with a 10 key, unscrew the nut and remove the bolt
Disconnecting the lever post from the rear axle bracket
Holding the bolts of the regulator bracket with a 12 wrench, unscrew their nuts with a 13 wrench and remove the bracket with levers
Install the bracket and regulator in reverse order, and then bleed the brake system
