I noticed my clutch, though it still works good, the pedal feels spongy like a brake line with air in it. Since it is hydrualic, I was wondering if there is any way to bleed the air out. If i pump it a few times ,it tightens it back up...Thanks in Advance...Cameron

 

Are you sure you aren't pressing on the MIDDLE PEDAL? The BRAKE PEDAL? lol, That sounds exactly like my brake pedal...let me ask this though, it is ok if that is like that on the brake right? now go along with Cameron's post...I hate trying divert it to me, but Cameron, take the red carpet!

 

I would do a gravity bleed on the system. If this doesn't fix it:

Likely: It sounds like you have an internal leak....seal may be going bad on the cylinder piston.

Possible: If you have high mileage on the clutch, there may be some uneven wear on the friction surface where some of the spring fingers may be sticking out more than the others and pushing the slave piston back into the bore.

 

How do you do a gravity bleed? No Homer, I know I am not hitting my brakes. The brake pedal is tight, and stops my truck on a dime.

 

If this doesn't work it is likely the (clutch) master cylinder is bypassing the internal seals. I am assuming that you are not losing fluid.

If you are real low on fluid, the slave could be leaking. I am not sure where the slave is located. It may be bolted to the side of the trans and drive a fork. It may also be directly on the trans input shaft and the bleeder is through a port on the side of the bell housing. Trace the tubing out of the cylinder to locate it. If it has the type that is attached to input shaft of the trans be careful. You don't want to wring off the bleeder in the driveway with that kind. If you have this type and it is leaking the trans will have to be pulled to replace it.


Once you have started this process DO NOT touch the clutch pedal until it is done or you will need a buddy to help you bleed the system.

1. Take the lid off of the cylinder and top it off. Leave it off until done.
2. Open the bleeder valve on the slave. Put a catch pan under the bleeder. Let gravity draw the fluid through the system. Keep adding fluid to the cylinder as it goes down.
Do not let it completly empty or you will need a buddy to help you bleed the system.

You should notice a change in color as the old fluid is displaced by the new. I would run about a pint through it. This should push any air out as well as flush the old fluid. The old fluid may have had excessive water in it and been boiling. Brake fluid is hygroscopic and absorbs water out of the air.

3. Close the bleeder. Top the resevoir to the correct level. Now you can try the clutch pedal.
