Removal
To remove the clutch pedal, perform the following operations in sequence.
1. Drain the brake fluid.
Fig. 14.13. Master brake cylinder and brake booster: 1 – connecting nut (15 Nm); 2 – nut (25 Nm); 3 – connection of brake system pipes (15 Nm); 4 – brake fluid level sensor connector; 5 – master brake cylinder assembly; 6 – connecting tube (15–18 Nm); 7 – vacuum hose (with built-in check valve); 8 – pin; 9 – washer; 10 – gasket; 11 – retainer; 12 – brake booster; 13 – Rear brake pressure regulator bracket

2. Disconnect the brake system pipes 3 (Fig. 14.13) from the master brake cylinder.
3. Disconnect connector 4 of the brake fluid level sensor.
4. Unscrew the nuts and remove bracket 13 of the rear brake pressure regulator.
5. Remove the brake master cylinder 5 as an assembly.
6. Remove the vacuum hose (along with the built-in check valve)
7. Remove connecting tube 6.
8. Remove spring retainer 11.
9. Remove washer 9.
10. Remove pin 8.
11. Unscrew 4 nuts and remove the brake booster 12.
12. Remove gasket 10.
Installation
Installation is carried out in the reverse order of removal, taking into account the following.
1. When installing the brake master cylinder assembly, it is necessary to adjust the clearance between the brake booster pushrod and the primary piston.
Fig. 14.14. Measuring the clearance between the brake booster pushrod and the primary piston: a – measurement of size A; b – measurement of dimensions B, C and D; 1 – measuring bar
Gap A (Fig. 14.14) is defined as the difference in dimensions B, C and D: A = B–C–D. The nominal gap is 0.6–0.8 mm.
Fig. 14.15. Changing the length of the pusher by turning the pusher adjusting screw
2. If the measured clearance value does not correspond to the nominal value, adjust it by changing the length of the pusher by turning the pusher adjusting screw (Fig. 14.15).
3. Fit the vacuum hose all the way into the hexagon of the connecting pipe on the engine intake manifold and secure the hose with a clamp.
4. Fill with brake fluid.
5. Remove air from the hydraulic drive of the brake system.
6. Adjust the position of the brake pedal.
