The valve is controlled by the movement of the stabilizer and regulates the hydraulic pressure on the rear brakes to prevent the wheels from locking up during hard braking.
On some models with rear drum brakes, the valves are combined with the wheel brake cylinders.
Examination
To check the functionality of the pressure control valves in the brake system, it is necessary to use special equipment. Therefore, these works should be carried out only at a service station.

Removal
1. Raise the rear of the vehicle and support it on stands.
2. Wipe the area around the connections (indicated by arrows) piping on the valve. Apply installation marks to the valve and piping.
3. Unscrew the connecting nuts and disconnect the brake pipes from the valve.
4. Unscrew the valve mounting bolts (1), disconnect the valve drive spring (2) from the suspension and remove the valve from under the vehicle.
Installation
1. Clean the brake pressure regulating valve completely and lubricate the threads of the valve mounting bolts with an anti-loosening agent (Loctite Frenetanch).
2. Install the valve in place and connect the valve control spring. Tighten the valve mounting bolts to the specified torque.
3. Connect the brake pipes to the valve and screw them on with the union nuts.
4. Bleed the brake system.
