Subject: | Clutch Pedal Sticks to The Floor and Will Not Return |
Models: | 2008 Chevrolet Corvette, Corvette Z06 |
| Equipped With A Manual Transmission |
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Customers may comment or technicians may notice the clutch pedal on some 2008 Corvettes may stay on the floor when depressed.
Recommendation/Instructions:
BEFORE ANY PARTS ARE REPLACED the technician should follow the procedure listed below:
- The engine should be off, transmission placed in neutral and the parking brake applied
- Verify the clutch reservoir is filled to the "fill line." DO NOT remove the cover to inspect. Inspect the fluid level from the side of the reservoir. If additional fluid is required use only DOT4 fluid from an unopened container.
Note: There is no substitution allowed other than DOT4 fluid.
- If the pedal is on the floor pull the pedal back to the full up stop and hold for one second. The fill port in the master cylinder is at the very top of the stroke. If the pedal is not fully returned to the top of the stroke, new fluid cannot enter
the master cylinder from the reservoir.
- Repeat the above step three times. If the clutch pedal does not freely return, repeat steps three and four.
- Check the reservoir to insure the fluid is still full.
- Drive the vehicle to insure proper clutch engagement
The Corvette uses a self adjusting clutch and some change in pedal feel or pressure are normal as the clutch adjust.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
