Pinpoint Test A: Clutch Slippage

Normal Operation

Clutch pedal movement is transmitted by fluid pressure to the slave cylinder, which in turn moves the clutch diaphragm spring, disengaging the transmission input shaft from the engine flywheel. The clutch master cylinder uses brake fluid and shares a common reservoir with the brake master cylinder.

This pinpoint test is intended to diagnose the following:
- Clutch pedal
- Clutch pedal pivot
