Hey guys, i was driving and all of a sudden, ihad no clutch, there was no pressure,
I went to the engine bay, and took a alook at the clutch slave cylynder, and found out that the rubber booot was swelling up ,
what would the problem be, the cylynder its self or somethign else

thanks

 

Did you recently do anything with the hydraulic system ie. brakes or clutch?

It might be air.

 

what rubber boot are you refering to? the boot on the piston at the end of the line is supposed to be the collapsible kind, like a spring. I am sure I am just not thinking of the properly terminology because I can't explain it any better. In any case this may appear to be bulged out or swelled, but it is in fact not sealed so it doesn't make any difference what it looks like.

I would definitely think air in the line at first, especially with no pressure on the pedal. If you have been doing anything to the clutch line, or even the brake lines like Adam suggested as well, then you need to do a better job bleeding out the master cylinder and all the lines. Start from your farthest point from the cylinder if you didn't know to. the only other thing I can think of that would cause a lack of pressure (aside from the clutch itself of course) is a leak somewhere. You didn't say whether or not you checked the fluid level, which is the first thing you should do if you haven't. Low fluid means it had to go somewhere and you probably have a leak somewhere in the system.
If you can drive it at all I wouldn't recommend doing so.

 

Okay, so i thought it was the slave cylyinder, the brake fluid is fine, i put on the new SLave Cylinder and now the is deff no clutch, i had my buddy pump the clutch then i would open the air hole, and a little air comes out, but the clutch is not getting hard at all. Not even the arm that is connected to the TO bearing is moving
so the fluid is good, but there is still no clutch, I am going to take pics rite now so you guys can see what i'm doing.
And yes i did put a new clutch in last month
but nothing to the brake lines

 

what about the throwout bearing? who put the clutch in?

 

I put the clutch in, everything was working fine till this morning,

 

air comes out? I hope thats a mistype because there is supposed to be only fluid, not even little bubbles in the fluid anymore.

Did you check the clutch pedal and piston pushrod?

How is the fluid flow, very slow coming out or obviously unrestricted. What clutch did you put in?

Do you have the knowledge to put a clutch in or was this something you decided to try? I've never put a clutch in but I would try on an easy vehicle. I don't know if i would try on my RA though. that's why I am questioning you ability, not because I think you are an idiot I don't think that, but it sounds like something is very broken and it's most likely going to be attributed to your clutch install.

I would check everything you can check without taking the clutch out. Start at one end and don't skip anything, even if you don't think it's the problem. How are the brakes acting anyway, or can you tell with the clutch not working?

 

Sounds to me like the old slave cylinder was leaking past the piston seal into the rubber boot. That would explain the loss of pressure and the swelling boot.

Then you replaced the slave cylinder and haven't bled all the air out of the lines yet.

Go get yourself another bottle of brake fluid, fill the clutch reservoir to the top, and open the bleeder screw. Let it gravity bleed (don't pump the pedal) until the fluid is below the full line, then close the bleeder screw. Attach a short piece of vacuum hose to the top of the bleeder, and put the other end in a container with a little fluid in it. Fill the reservoir to the top again, and have a friend push down and hold the pedal while you open the bleeder. A shot of air and/or fluid will come out, then close the bleeder again, and have the friend pull the pedal back up. Repeat until no more air bubbles come out and you are below the full line on the reservoir, then close the bleeder, fill the reservoir to the full line, and check for proper operation.

 

Thats whats i was doing, but i did not let it gravity bleed, I just had him hold the clutch in and i would open the bleeder valve then close it again, and he would release the pedal, there would be a few squirts of fluid out. but i will try that gravity bleed option

Thanks alot

And yes i put a rrm stage 1 clutch in and everything was fine, until the slave cylinder was leaking and the boot filled up with fluid,
thanks alot for you rhelp guys

 

You're bleeding it wrong. Opening/closing the valve while the pedal is held down won't bleed the line.

1. Open valve.
2. Push pedal.
3. Close valve.
4. Lift pedal.

 

Otter, thats not working. My clutch does not get hard at all? Now when i push pedal, open valve, close vlave and release pedal, after a few times, the clutch becomes hard.....?

if thats the wrong way....Thats the only way that it works......

 

Was this problem ever solved because i have the same issue
