My car's high pressure clutch hose developed a leak. I replaced it and then put in new clutch fluid and bled it using a Motive Power Bleeder.
The clutch pedal will still not return from the floor after being depressed.
I'm suspecting the slave cylinder and/or master cylinder but don't want to immediately just start throwing parts at it. I understand it would be best to replace both at the same time.
Is there any way to test them? Could anything else be the culprit?
The clutch was working perfectly before the hose started leaking.
Thanks.
Is it possible that the master cylinder piston is "stuck" in the master cylinder because when the hose blew the pedal went all the way to the floor without any back pressure to return the piston to the most forward position?
i can't say this enough. when replacing one part of an hydraulic clutch system, replace them all. contamination cannot be removed any other way.
further, if one part has failed, it is better than a 50% probability that the next weakest one will soon afterward, until all are changed.
that being said, it is possible that you have a worn pivot point, which would put the pedal out of adjustment, and cause it to "tip over" and stay on the floor. there is a page in the workshop manual about the clutch pedal position, and how to adjust the pedal to achieve it
I had the same thing happen about two months ago. Pedal went to the floor and replaced the high pressure line. At flash's recommendation I asked to have the master and slave cylinders replaced when they both looked ok. After removing it the slave was bad and would have gone soon.
Is any one of the cylinders damp or wet? Try fiddling with the rubber boot of the slave, maybe fluid will come out...
Chances are that there is still air trapped inside somewhere. Bleeding the clutch can be a a real PITA, motive or not.
It is also very important to check your firewall for any movement when depressing the clutch pedal. Any "flex" on it will prevent the pushrod of the master cylinder to be engaged fully and thus all air being forced out of it. Your clutch could have worked just fine before but bleeding it would become impossible. Ask me how I know :-)
Bleeding the clutch is a real pain
