    clutch master cylinder or slave cylinder?

    hey i just bought a silver 1998 svt contour, and the clutch pedal is floppy, like there is no resistance at all in it, no pressure to push back when i push on it, it starts no problem at all, i dont have to push the clutch at all and i can start it. my question is the problem a slave cylinder or a clutch master cylinder?? i'm hoping it's the clutch master cylinder so i don't have to take the tranny out. any help is kindly appreciated

    The slave is like a little balloon that inflates with fluid and squeezes the pressure plate. If it fails, it doesn't inflate - no resistance.

    Have you noticed any fluid loss? Check your brake reservoir.

    Both the master and the slave will cause the same symptoms, you are going to have to get in there and look. It could even be a line rupture.

    Yep, if you try to bleed the slave, which is very easily done with a Mighty-Vac and 8mm (IIRC) wrench. If the slave doesn't bleed, but instead does nothing but leak air bubbles, you are in trouble. It very well could be the slave cylinder, but that requires pulling the trans from the car and cost 100x more to fix than replacing the master. Both parts are about the same costs, but replacing the master can be done in your driveway. I'd hate to see you go through the trouble of replacing the slave to find out it's the master, so take the cheapest path first and replace the master. After replacing the master, try to rebleed the clutch. If it works, that was the problem. If it doesn't, prepare to pull the engine/trans to replace the slave

    I had the same problem, but the trans was brand newly rebuilt, so I knew for a fact that the slave wasn't the problem. I replaced the master and the problem was solved.
