Clutch Hydraulic System Diagnosis

CLUTCH HYDRAULIC SYSTEM DIAGNOSIS

IMPORTANT: Before attempting to repair the clutch hydraulic system for any reason other than obvious failure, the complaint should be identified using the Condition-Cause-Correction chart.

The clutch hydraulic system in the vehicle is composed of a clutch master cylinder, clutch hydraulic line assembly, and clutch slave cylinder. These parts are serviced separately and require a bleeding procedure to be performed after making any repairs to the system.

IMPORTANT: There is no way to measure clutch slave cylinder travel.

1. Remove drivers lower I/P closeout panel (hush panel).
2. Measure travel of clutch master cylinder push rod while depressing clutch pedal. Push rod travel should be 28.2 mm (1.1 inch).
- If pedal travel is insufficient, check for:
- Carpet or floor mat under clutch pedal.
- Faulty or damaged clutch pedal or pedal bushings.

- If pedal travel is ok, check hydraulic system for the following:
- Fluid leaks
- Damage to front of dash
- Damaged clutch master cylinder
- Damaged clutch slave cylinder (requires transaxle removal)
- Air in system

3. If air is suspected in hydraulic system, bleed system.
