Removal
1. Jack up the rear of the car and place it on supports.
2. Disconnect the drive spring from the valve (the location of the pressure regulator valve is shown in the accompanying illustration).
3. Disconnect the brake pipes from the valve. Plug the open ends of the pipes to avoid excessive fluid loss and to prevent dirt from entering the hydraulic system.
4. Loosen the mounting bolts and remove the valve from the vehicle.
Installation
Installation is carried out in reverse order.
1. Tighten the mounting bolts to the required torque.
2. Bleed the brake system.
3. Carry out road tests of the vehicle, checking the proper functioning of the pressure regulator valve. If the rear wheels constantly lock up when braking, the valve should be taken to the workshop of the manufacturer's dealership to have the drive spring adjusted.
Attention! Do not attempt to disassemble the valve under any circumstances!
