If shallow scratches or traces of oxidation are found on the surfaces of metal parts, wipe them with 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 should be: under a force of 13±2 N (1.3±0.2 kgf) - 80 mm, under a force of 120±6 N (12±0.6 kgf) - 160 mm.
The clutch pedal release spring has a length of:
- under force 33+4–2 H (3.3+0,4–0,2 kgf) – 130 mm
- under force 46+4,5–2,5 H (4.6+0,45–0,25 kgf) – 155 mm
The length of the clutch servo spring under a force of 200±20 N (20.4±2 kgf) should be 120 mm, under a force of 599±60 N (59.9±6 kgf) – 152 mm.
