clutch spongy

**JDCAMARO99** · 08-25-2009, 07:15 AM

My clutch pedal seems to want to stick to the floor every so often. It's not all the time though. I had the hydraulic fluid changed and bled. I noticed it was pretty dirty. Not more than a week later my new fluid is dirty again and I still have the same issue. Is this a clutch master cylinder problem???

Yes sounds like a master cylinder problem.

Agreed. Also don't forget to go ahead and do the slave cylinder as well, majority of the time if you do one and not the other, the one you didn't do will cause the new part to go bad. Try them, should fix the problem. Good luck

Thanks for the help guys! I will probably end up changing both the master and slave out. I was going to try to get away with just the master cylinder, but It makes sense to do both. It's driving me crazy! My clutch will grab right off the floor sometimes and then it will grab at the top.... and then it will stick to the floor. Well, hopefully this takes care of the problem. Is it a good idea to do the drill mod before installing the master??

No problem man. Tell you what, in exchange for my help, (I'm still relatively new to LS1s) what exactly is the drill mod? haha.

Yeah man definately do both at once. Shouldn't be too bad of a job.

yes do the drill mod!

Well from what I've read, the steel line from your master cylinder to the bell housing has a tiny opening. It only lets so much fluid pass through. I guess you take a bigger size drill bit and make a bigger opening at the bell housing connection..... allowing more fluid to pass.
