clutch pedal problems

[tronno]

I've just installed a new clutch in my car and have been experiencing problems with the clutch pedal. Normally the clutch engages about two inches off the floor,and cant adjust the pedal anymore to get it to engage more off the floor. Sometimes the clutch would engage close to the top and if I floor it, the clutch would slips because its not engaged all the way. When this happens, the pedal only goes in half way until it feels like it's hit a wall(wont go any further,like clutch being pressed in all the way). When i go to adjust the clutch pedal to get the clutch to engage closer to the floor, I hear something like air or fluid coming out of the master cylinder.then the clutch wouldn't disengage, so i had to adjust the clutch again to get it to engage normally(two inches off the floor). I think it might be the master cylinder but I never herd of someone having the engagement point of the clutch to change that drastically, and cause the pedal to only be able to be pressed in half way. What do you guys think? Any help would be appreciated.

check your haynes manual on the topic of bleding cluches (page 8-8) if you dont have a have the book tell me and i will copy the page for you i had a simular prob and it worked for me

check around the master cylinder and slave sylinder for fluid. The should both be dry. Also check under the carpet where the master cylinder goes into the cabin area. If one or both are wet then you most likely have a leak and they will have to be replaced/repaired. If they are dry then I would try bleeding like Tony said. If the bleeding doesn't do it then you may want to look into rebuilding/replacing the master and slave cylinders. If you haven't done so in a long time, then it would not be a bad idea to rebuild/replace them anyways since they do tend to go bad after a while. I've had trapped air cause me problems as well as bad master and slave cylinders so I know about both.

If you aren't familiar with bleeding just follow the guide in the book but use this hint. Take a 20 oz soda bottle and drill a hole in the lid large enough for whatever hose you will attach to the slave cylinder to get the fluid from it. Put a tight loop in the hose (like the first loop in tieing your shoe) and put one end on the slave cylinder nipple and the other through the soda bottle lid. This will help prevent any air from traveling back into the slave. And by a tight loop, I mean kind of tight but not kinked.

Something I learned the hard way is that the clutch cylinders, espically when old, are very weak. I noticed you put a stage 3 clutch in, how many lbs of force does it hold, and is the clutch pedal a ton heavier? If so you probably blew or damaged one of the cylinders and need to have them replaced. I put my SBR 4000 in and blew the cylinders in a month. Chances are thats it or something close to that.

My clutch has been bled quite a bit... and the pedal still feels too soft... it's kinda pissing me off. I do not see any leaks anywhere either and I've bled it so much that I don't feel like it's doing anything.

it really still sounds like a leak or air in the line. It is possible that air is still trapped in the line but I would bet that you have an internal leak somewhere in either the master or slave cylinders or maybe you sprung a tiny leak in the line somewhere. How long has it been since you last replaced your master and slave?

I think its 2100lbs of force and yes it is a lot heavier. @hen you said clutch cylinders,do you mean the master and slave cylinder? I have just replaced those but the pedel pressure still changes sometimes. i might need to bleed it some more. What could cause the engagement point of the clutch to change?
