Pressure regulator

The pressure regulator regulates pressure in a drive of brake mechanisms of back wheels depending on loading on a back axis of the car. With increase in loading it provides passage of a brake liquid to wheel cylinders of back brakes from what pressure in their contour raises and the overall performance of back brake mechanisms improves. Do not assort a pressure regulator.

Check of function of restriction of pressure


    Remove a regulator of pressure from the main brake cylinder. Connect two manometres, one – on the entrance party and one – on the party of an exit of a regulator of pressure.

After connection of manometres remove air from brake system.

    Press a pedal of a brake and measure entrance and target pressure.

If pressure are in limits of admissible amplitudes, as is shown in drawing, the pressure regulator is serviceable.

    Remove manometres and connect tubes of brake system in initial position and remove air from brake system.

Installation of a regulator of pressure


    Establish the main brake cylinder.
    Tighten connecting nuts of fastening of tubes and remove air from brake system.

The moment of an inhaling of connecting nuts: 13–17 Nm
The moment of an inhaling of nuts of fastening of a regulator of pressure: 35–55 Nm
