Important: Before attempting to repair the clutch hydraulic system for any reason other than obvious failure, the complaint should be identified using the Clutch Diagnostic 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 the clutch slave cylinder travel.

  1. Remove the drivers lower I/P closeout panel, or hush panel.
  2. Measure the travel of the clutch master cylinder push rod while depressing the clutch pedal. The push rod travel should be 28.2 mm (1.1 in).
  3. If pedal travel is insufficient, check for the following:

    • The carpet or the floor mat is under the clutch pedal.
    • The clutch pedal or pedal bushings are faulty or damaged.
  4. If the pedal travel is OK, check the hydraulic system for the following:
  5. • Fluid leaks
    • Damage to the front of the dash
    • Damaged clutch master cylinder
    • Damaged clutch slave cylinder, requires transaxle removal
    • Air in the system
  6. If air is suspected in the hydraulic system, bleed the system. Refer to Clutch Hydraulic System Bleeding.
