clutch biting point is stupid

[Spiker]

Ok here is the deal. My cars clutch got stuck to the floor one day. I look at the fluid in the master and its black. I remove my damper box I bleed the fluid out and the clutch has pressure. Now here is the problem. The biting point is at the top of the pedal. I tried adjusting the push rod for the master all the way out and I tried all the way in. Either way the biting point stays at the top of the clutch pedal. Plz help. Also I bled the lines so much but the thing still kinda is bubbly like millions of small bubbles not big ones. However my clutch got plenty pressure. Real stiff. Just the point it bites is all the way up...

If you still have bubbles you either have a leak somewhere or the bleeding wasn't done right.

Have you checked the master/slave for leaks? $50 will buy you both.

Scotty would that make it bite way up there though? I bled it like 1000000 billion zillion times the thing has a lot of pressure...

try bleeding it more i dont think you are doing it right.you should have no air bubbles what so ever. and try ajusting ur rod on the master do not have it pushing ur pedal as far as it can push you are sopossed to have about a half on an inch play in the pedal till you feel pressure..in other words pull ur pedal all the way out with ur hand an when you push it back in you should have about half inch with play from stopper to pressure..

i tried adjusting it in and out and everywhere inbetween its still at the top and the pedal has choke pressure!!! i bled it right...

The system is pretty simple, two pistons, a pipe in between with fluid. When you bleed the fluid coming out should look just like it goes in, clear with no bubbles. Bubbles=leak.

Sounds like a leak or bad master/slave. Did you look for fluid under the clutch pedal, or under the dust cover on the slave?

The original problem of the pedal getting stuck to the floor means a leak.

I guess the clutch lines could be clogged also.

Ok I think my clutch is f***ed.. maybe u don't understand what I'm trying to say.. my clutch pedal biting point is at the top of the pedal I can jus push the pedal like 1inch and shift doesn't need to be all the way to the floor. When I release my clutch and give gas it doesn't bite untill I'm almost all the way off the pedal. My clutch is bled it has a lot of pressure...

[cleopp3]

did you adjust the master cylinder rod?? the rod may need to go further into the master cylinder. therefore giving the biting feel lower down in the pedal travel. what happend to mine was that the shaft that the TOB slides on busted so It fet like as soon as I let the clutch start coming up it grabbed. Peek into the boot where the fork is on the side of your transmission and have someone press down while u watch it function. otherwise follow this link and try to adjust it,best link i could find hope this helpz!http://nico.zeroforum.com/zerothread?id=289612

sup man..im gona chime in with some info to think on....they make different fluids for different aplications..most people never think about whats in there systems untill they have problems later on...you said the fluid is black..to me that says "Burnt up" your probly runnin dot 3 in there..you might want to concider running a higher temp rated fluid like dot4 or even dot 5.1..donot used dot5 thou...its not compatable with dot 3,4 or 5.1 allso known as dot 4.5 fluid..the higher the number the higher the temp rating before the fluid breaks down...

as for the system...i would change all the lines and the slave master out man...there is debris in there and that could couse other issues while your driving if it fails..good luck..hope this helps in some way.

I have a similar problem.

New master and slave, throtoughly beld, and it bites ALL the way at the top of the pedal. Did the same thing even with my SR. I'm thinking it may be a bad clutch fork pivot.

I tried adjusting the master and no luck.

definitely get a new master/ slave cylinder. My clutch had tons of little air bubbles in it and just replacing the slave was enough along with the continuous bleeding. but it works.

[scottydog]

With bubbles or cloudy fluid you have a hydraulic problem. Replace your master/slave cylinders and rebleed first.

Then adjust your clutch pedal rod. If it bites somewhere in the middle of the pedal movement it's good enough.

If at that point your clutch slips you need a new clutch. replacing the clutch is a real PIA so do the other easy stuff first.
