Pressure regulator

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

Check of function of restriction of pressure


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

After connection of manometers 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 regulator of pressure is serviceable.

    Remove manometers and connect tubes of brake system in initial situation 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.

Moment of an inhaling of connecting nuts: 13–17 N • m
Moment of an inhaling of nuts of fastening of a regulator of pressure: 35–55 N • m
