If shallow scratches or traces of oxidation are found on the surfaces of metal parts, wipe them with a fine-grained sandpaper; replace non-metallic parts with new ones at each disassembly.
Check the elasticity of the springs. The length of the brake pedal spring must be: under a force of 13±2 N (1.3±0.2 kgf) – 80 mm, under force 120±6 N (12±0.6 kgf) - 160 mm.
The clutch pedal return spring has a length of:
- under effort 33+4–2 H (3,3+0,4–0,2 kgf) – 130 mm
- under pressure 46+4,5–2,5 H (4,6+0,45–0,25 kgf) – 155 mm
Clutch servo spring length under force 200±20 N (20.4±2 kgf) should be 120 mm, under a force of 599±60 N (59.9±6 kgf) - 152 mm.
