My stupid F-ing car is at it again. Now I drive her pretty easy I baby the crap out of my car because I just dont want to mess up anything. However, my clutch pedal has been gettin really soft lately. I've just done the clutch master cylinder 7-3-2010 because I was told to replace it then I bled the clutch line, now i've taken it out for a spin and for a few minutes it was fine then all of a sudden the clutch pedal goes to the floor and I have to keep pressing the clutch pedal to get it to stiffin back up for some reason. I have a stage 2clutch in there and fidanza flywheel so im pretty sure that there fine. I dont know why I can't keep pressure in the damn clutch I have bled that damn line from here to hell please someone point me in the right direction before I sell this P.O.S

 

maybe defective master, if there are no external leaks then the cup seal inside the master is probably defective

 

yep it could be leaking internally, replace it my friend

 

If you already replaced the master cylinder and properly bled the hydraulic system, then the slave cylinder may be the problem.

 

Are you using the nipple on the slave to bleed it, if so, take it all the way out and have a friend push the pedal, you will feel the pressure better against your finger. Let up a little to allow fluid to squirt, and press hard to release pedal, once all the air is out dont worry about putting the nipple back in, it will bleed again, only better next time.

In the end, you may be bypassing internally, I have fixed these by just disassemble and reassemble with the same parts.

 

I havn't taken the nipple all the way off so I guess I will try that. Like I said I just brought the new clutch master cylinder this past Saturday and everything felt fine for about 20min then all of a sudden the darn pedal got soft again so im lost.

 

New parts dont always work, and sometimes the old partner (slave) will be forced bad. Another example would be if you changed an ignition control module (ignitor) but didnt change the coil, either the old coil or the new ignitor may burn up quickly. Some things just go better together, like hamburgers and cheese.

 

Hey I fixed the issue. It actually was my slave cylinder, i replaced it last nite and its been driver super good thanks for everyones help

 

Good for you. Personally I always start out with the cheaper part. Around here slave is $12, master is $90.

 

Starting to troubleshoot by buying the cheaper parts first is not TROUBLESHOOTING, its shooting yourself in the foot, if you are working on someone elses car and you charge them money to replace parts that they dont need then you are going to kill your reputation.

Sorry, I use to work with a guy and that was his style. You, Sir, may be a novice and just some guy who likes to help others out and I wish no ill will to you, but my ex-coworker was supposed to be a professional and I hate it when I hear people say things like that. I will get off of my soapbox now.
