Repair B3-B4/Passat B3-B4 Volkswagen Passat>> Brake system>> Pressure regulator

Fig. 12.19. An arrangement of a regulator of pressure on the car: 1–pressure regulator; 2–the operating lever


The regulator of pressure changes brake effort on back wheels depending on car loading. Thus, the probability of blocking of back wheels decreases and stability of the car improves when braking. The pressure regulator (fig. 12.19) is located at the left on a back axis and (fig. 12.20) copes through a spring .

Fig. 12.20. Regulator of pressure of back brake mechanisms: 1–pressure regulator; 2–nut; 3–spring; 4–nut; 5–adjusting lever; 6–bolt of fastening of the adjusting lever; 7– bolt of fastening of a regulator of pressure


Check of a regulator carry out in the following order:
work carry out in situation when the car costs on wheels;
ask the assistant to supervise work of a regulator of pressure. Press against the stop and release the brake pedal, thus operating lever of a regulator should move.
