Installing a pressure regulator on a car
1 - pressure regulator; 2 - lever; 3 - nut; 4 - bolt; 5 – loading spring; 6 – an arm on a beam of a back suspension bracket
Pressure Regulator Parts
1, 2, 7, 10 - bolts; 3 - lever; 4 – loading spring; 5 - nut; 6 – an arm on a beam of a back suspension bracket; 8 - pressure regulator; 9 - bracket; 11 - brake pipe going to the rear left brake mechanism; 12 - brake pipe going to the rear right brake mechanism; 13, 14 - brake pipe coming from the master cylinder
The pressure regulator, installed in front of the rear axle beam, prevents premature blocking of the rear wheels relative to the front ones. This allows you to more effectively use the braking properties of the car and prevent possible skidding of the car.
Attention! The pressure regulator cannot be repaired; in the event of a malfunction, it must be replaced as an assembly.
Examination
With the car on the ground, the assistant should sharply press the brake pedal - the regulator lever should move. Otherwise, the pressure regulator is defective and must be replaced.
Adjustment
1. If the pressure regulator is properly adjusted, when braking on a level paved road, the front wheels should lock slightly before the rears.
2. If the rear wheels lock before the front wheels, pre-adjustment can be done by loosening the load spring 5 (see fig. Installing a pressure regulator on a car) (to do this, loosen the nut of its fastening on the lever).
3. If the front wheels are blocked much earlier than the rear ones, tighten the spring.
4. A more precise adjustment using special tools can be carried out at a service station.
Removing
1. Place a container under the pressure regulator to collect the brake fluid that will flow out of it when removed.
2. Mark the brake pipes 11-14 (see fig. Pressure Regulator Parts), connected to the pressure regulator so as not to confuse them during installation.
3. Having unscrewed the fastening nuts, disconnect the four brake pipes from the regulator. Plug the tube holes.
4. Disconnect the regulator lever 3 from the load spring 4 by unscrewing the nut 5 and removing the bolt 2.
5. Turn away a bolt 1 with an internal hexagon and remove a pressure regulator from an arm on a body.
Installation
1. Install pressure regulator in reverse order.
2. After installation, add fluid to the reservoir and bleed the brake system (see subsection 9.9.6).
3. Adjust pressure regulator (see above).
