So I have this problem. Its been bugging me for the past 6-9 months. Ive just been real lazy to take care of it. I swapped my car from auto to 5spd a couple years ago. I bought the Master and the Slave cylinders brand new from the dealer. The clutch pedal assembly was also brand new from the dealer. Anyway, Ive been loosing pedal pressure. If I roll up to a stop sign and hold depress the clutch pedal for about 15 seconds while in gear, the car stalls. I sometimes have to pull the pedal out with my big toe and pump it a couple times to release the gear. Now, the entire system was bled about 3 times since I did the conversion. There are no fluid leaks anywhere from top to bottom. Im thinking my slave cylinder is crapping out on me. If that seems to be the case I dont mind replacing it since its pretty easy but what do you guys think?

 

Sounds like it could be leaking pressure internally, I'd try doing the slave

 

Yeah thats what I was thinking. I was hoping it wouldnt be since its only about a year old.

 

Im going to try swapping it out with my spare cylinder and see how that goes..
