Clutch Nightmare!!!

[Nordon]

So I replaced my master cylinder about a month ago, and finally through the help of this site was able to reverse bleed the system.

Unfortunately, I began losing clutch again, and reverse bled a couple of more times over the weeks before I installed a new slave cylinder.

I noticed my slave was clearly shot, so I figured this would end my problems forever. Wrong. Same problem.

I have followed every line and do not see a leak ANYWHERE.
I don't know what to do.
The good news is, I guess, that I can reverse bleed in my sleep, and it only takes me about 10 minutes start to finish.

I can't go on like this forever though.
PLEASE anyone with any knowledge of what might be the problem or even ideas help me!

Just to clarify ..You changed the clutch master, yes? and after changing the clutch slave you are still losing brake fluid?

Yep, the master was changed first. The thing is, I don't know if I am losing fluid, because I don't see any leaks, and it just doesn't make sense. I am losing pressure though. Is it possible for some air bubbles to creep up on me?

maybe your master cylinder (brake master cylinder) is worn out and needs a rebuild or to be replace. i assume since u did all the bleading you know that the clutch feeds off the brake master cylinder. also check your calipers, they could also be faulty, had that probelm on mine

A leak in your brake system wouldn't effect your clutch unless the brake fluid level in the reservoir got way low. Could that be the case? Have you checked up under the carpet (clutch master) for brake fluid ?

Again too clarify, when your clutch fails you check your brake fluid reservoir (particularly the aft chamber that feeds the clutch) and you find it low (below the level of the hose that feeds the clutch master cylinder) and you cant find the leak...is that right?

Is it possible you are sucking in air thru the hose that connects the brake master cylinder reservoir to the clutch master cylinder? My 307d was low on hydraulic fluid once and took a gulp of air when I went around a corner. The system is designed so that low fluid causes the clutch to fail before the brakes, at least it was on my 307d.

Mine must be messed up then cause my brakes definitely went out way before the clutch stopped working.
I didn't know what it was and I wanted to drive my car around because I just got it so a basically drove it with back brakes only.

No leak under the carpet-- my clutch master cylinder was replaced so i made sure afterwards to check for leaks. I don't find the brake fluid reservoir low-- it seems to hold its fluid. Cant seem to find a leak anywhere..

This seems probable, but I don't see any leak in that hose either--- but do you think its possible that air is getting in but brake fluid isn't leaking out?

OK, this sheds a little more light on the situation. The rear chamber of the brake fluid reservoir ran dry and you lost brakes and clutch, then what? What made you think your clutch master & slave were bad? were they leaking then? Brake fluid can leak into your brake booster and you'll not see a leak, Sorry guess I'm having a hard time getting the picture here.

What is the specific issue here? Car not going into gear? Is the clutch pedal firm? Do you have to pump a bunch to get it into gear?


Why don't you just sell me the car for what you have invested in it

Huh, how do you figure? "Nordon's" post is #1, this thread is kinda strange tho

After I reverse bleed, I will have a stiff clutch, but then I will slowly lose the clutch, until first I cannot put the car in reverse while it is running, and then I cannot get it into gear while it is running. I've not found that I can alleviate the problem with pumping, I only can regain my clutch by reverse bleeding again. This all started with a leaking master cylinder, which I replaced, for those who want to know.

Yes, this thread has gotten a little weird...

When you say "lose" the clutch you mean its going all the way to the floor without much resistance? I am fairly certain this is what you mean I just want to make sure its not a clutch disc/throwout bearing wear issue.

If you are properly reverse bleeding the system then one of your replacement parts is defective. Id start with the MC first since this is the first thing you had replaced.

Honestly I think your not bleeding it properly. If its a closed system and the plungers are relatively new then that pretty much leaves only one other issue and that air in the system.
