1. Establish the car on the lift or a viewing ditch, clear a regulator of pressure and a protective cover of a dirt. |
2. Cautiously remove a protective cover from a pressure regulator, remove the rests of greasing and clear connection "torsion-piston". |
3. Ask the assistant to press a pedal of a brake with effort 686–784 Н (70–80 кгс) and simultaneously observe of acting part of the piston of a regulator of pressure. |
4. If the piston moves concerning the case of a regulator of pressure upon 0,5–0,9 mm, twisting thus торсионный the lever the pressure regulator is efficient. Repeat 2–3 times pressing a pedal completely to be convinced of working capacity of a regulator of pressure. |
5. If by pressing a pedal the piston remains motionless that specifies on приржавление the piston to the case replace a pressure regulator. |
6. Having convinced of working capacity of a regulator of pressure and in absence of a leak of a brake liquid between the piston and the case of a regulator of pressure, cover with a layer of greasing ДТ-1 an axis and an acting part of the piston, put 5–6 г this greasing in a rubber cover and establish a cover into place. |
