Removal and installation
To remove the pedal bracket:
- remove the steering shaft bracket as described in the "Steering" section;
- disconnect the vacuum booster pushrod from the brake pedal by removing the locking clip 26 (Fig. 6-9) and removing the pin 24;
- unscrew the nuts securing the vacuum booster and clutch master cylinder to the bracket,
- unscrew the nuts securing the bracket to the body and remove the bracket, disconnecting the wires from the brake light switch.
Install in the reverse order. Make sure that the pusher is correctly installed in the socket on the clutch master cylinder piston.
Fig. 6-9. Clutch and brake pedal bracket parts: 1 - bracket; 2 - nut; 3 - spring washer; 4 - inner brake pedal bushing; 5 - outer brake pedal bushings; 6 - brake pedal; 7 - spacer sleeve; 8 - brake pedal release spring; 9 - outer clutch pedal bushings; 10 - hook; 11 - cap; 12 - clutch pedal limiting screw; 13 - nut; 14 - servo spring; 15 - inner sleeve of clutch pedal; 16 - plate; 17 - clutch pedal release spring; 18 - washer; 19 - pedal pads; 20 - bolt; 21 - clutch pedal; 22 - cotter pin; 23 - Clutch pedal pusher; 24 - finger; 25 - vacuum booster pusher; 26 - locking bracket
Disassembly and assembly
To disassemble, remove spring 14 of the clutch pedal servo, remove release springs 8 and 17, unscrew nut 2 of bolt 20, remove the bolt and remove the pedals together with the bushings.
To remove and install springs, use tool A.7-17.
Assemble in the reverse order. When assembling, lubricate the pedal bushings, spring ends, pushrod-pedal joints, and the end of the pushrod that contacts the clutch master cylinder piston with LITOL-24 grease.
Checking and repair
If the pedals are difficult to move, inspect the working surfaces of the pedals, bushings and axle.
If you find shallow scratches or traces of oxidation on the surfaces of metal parts, wipe them with sandpaper; replace worn outer plastic pedal bushings with new ones.
Check the elasticity of the springs. The length of the brake pedal spring should be. under a force of 12.8±1.96 N (1.3±0.2 kgf) - 80 mm, under a force of 117.5±5.88 N (12±0.6 kgf) - 160 mm.
The clutch pedal release spring is 130 mm long and has a force of 32.34+3,92-1,96 N (3.3 kgf) and 155 mm under a force of 45.08+4,41-2,45 H (4.6+0,45-0,25 kgf). The length of the clutch servo spring under a force of 199.92±19.6 N (20.4 + 2 kgf) should be 120 mm, under a force of 587.02±58.8 N (59.9±6 kgf) - 152 mm.
