clutch problem????, help! Options

[my96celica]

My car will start but will not go in gear. I replaced the clutch and master cylinder last year around this time. As of now the clutch pedal has no pressure. Has fluid but the peice that would move in and out when I push on the pedal does not move anymore. I think its my slave or master cylinder.

Do both at the same time, then gravity bleed it.

Gravity bleed = opening the slave bleeder nipple by just a hair so it drops 1 every 3secs or so. keep an eye on the master side that it doesnt run out of brake fluid. let the fluid cycle for about 25-45mins. then there shouldnt be any air in your lines

So you dont think it is my clutch or anything else?

[808celica]

how many miles on the clutch job?? I doubt its that unless you're a complete idiot like me who cracked my pressure plate in 3 places

What piece are you referring to?? the Slave pushrod or the clutch fork??

**Im sureyou have no pedal pressure because no fluid is pushing the slave pushrod which doesnt engage and dis-engage the clutch disk. If the slave pushrod doesnt move than its most certainly an internal leak in the slave or master cylinder. Since you say you have fluid I wont ask you to look behind the clutch pedal for fluid leaking. Have you tried bleeding the clutch lines yet??

THe clutch has around 10,000 miles on it. The slave cylinder does not move in and out when i push on the clutch. I had a little pressure on the pedal till I took the cap off the master cylinder to see if there was fluid in it. now there is no pressure. Should i bleed it before I go and buy the slave cylinder? There is no fluid leaking from the car.

Just go on ahead and get a Slave cylinder if its not moving. Is the Master cylinder still under warranty?? If the Slave pushrod doesnt move then there is nothing that's engaging and dis-engaging the clutch disk. Hence your problem of not getting into gears.

[my96celica]

So buy the slave and master cylinder? Do you think it is the pressure plate or anything major?

[808celica]

gotta focus on getting the pressure back. If the slave doesnt work then there is no way to tell if anything internal is broken without dropping the trans. with 10k i high doubt its broken.

well if you have time and patience i myself would get the slave (since it doesnt work), then if you still dont have pressure or very little pressure then change the master. you also gotta take proper bleeding of the lines into account. took me about 4 trys to get the lines properly bled.

[my96celica]

How do I bleed the clutch line if there is no pressure? How do I ever bleed it? Is it like bleeding my brakes?

[808celica]

just like bleeding brakes. are you gonna use the 2 person method or gravity bleed tech??
The slave cylinder has a bleeder nipple just like your brakes. Clutch line fluid is the same as brake fluid DOT 3.

It's totally either your master or slave cylinder, start w/the slave since they're WAY cheap, and bleed the hell out of it. If that doesn't work, it's your Master. Doesn't hurt to replace them both. Just don't mix up your CLUTCH master cylinder with your BRAKE master cylinder - it's a common thing to mix the two up. They're not the same thing.

Thanks guys! How long would you think it takes for myself to replace it? Is it hard?

[808celica]

how good are you with cars?? you'll need a range of sockets, shallow and deep ones. a swivel joint helps too. i'd say 45mins to get the master and slave out and in. then 1hr of proper Gravity bleeding. dont forget to bench bleed each part before install.

[my96celica]

Thanks ppl my car is up and running again.

[GriffGirl]

So which was it? Or did you just replace them both?

[my96celica]

It was the slave cylinder.
