No clutch pressure

Postby 240SR on Tue Sep 16, 2008 9:43 pm

My 240 has been sitting for about 8 months.Now the clutch pedal has very little pressure.
I bled the lines refiled and now there is no pressure, the pedal stays on the floor.
The master cylinder was replaced last summer and has a stage 3 bully clutch kit.
I have no Idea whats wrong cause all the parts are knew.

How does the slave cylinder look?

My guess is its done.

They tend to hate performance clutches, I am on my second. I think Nave is on his third.

To ask the obvious (cause sometimes it's necessary) did you bleed it at the clutch damper as well?

^^ If he still has it, the first thing he should do is get rid of that piece of crap... run your hardline directly to the softline going into the slave... Also like Alex said, your slave cyl is probably pooched. They're like $20 at Napa, mine lasted me a season and a half with an upgraded clutch. For $20 that ain't bad.

Ours are NAPA units too... but they only last a season with ACT HD 6 puck... so we get them exchanged under warranty :P. Its become part of the spring tune-up. Oil change, filter, slave cyl, charge the battery, giver!

Even before you replace it you should see the problem pretty quick... pull back the boot a bit and it will be soaked with brake fluid. They do tend to fail with the upgraded clutches, I keep a spare one in stock. :grin:

I replaced the slave cylinder and the master cylinder.The clutch is better,but I only feel the pressure after the clutch pedal is more than half way down.So now I don't know what else to try.
And I just found out my mechanic ripped me off.Last summer I had the master and the slave replaced at his shop.
I just took the slave cylinder off that he sapposedly replaced,and it's the original part.He charged me $70 for the part and $168 in labor,when he did nothing at all.I bought the slave cylinder for $35 and put it on myslef in 15 minutes.

I would go back with the core part and stab him with it.

Hey guys, i recently had the same problem with my clutch (no pressure). At first it seemed like it was because the slave cylinder was toast (it was leaking inside the boot). I replaced the slave but I still had the problem. With help from a Technician I work with, we found out that it was in fact the Clutch Damper (the box that has the thicker lines) that was causing the problem. We came to this conclusion because we ended up removing the damper and making a straight connection from the master to the slave. Presto, full clutch pressure after a quick bleeding of the lines. Hope this helps with anyones problems in the future.
