Help?! How do I remove clutch master cylinder? Options

[GriffGirl]

It appears my clutch master cylinder went out. I've replaced the slave cylinder already, so that leaves the MC which I believe is back-bleeding; can somebody point me in the direction of where I might find removal instructions? Or give me a rundown on how to remove the MC? I'm picking up a new one today and intend/hope to install it tomorrow.

Thanks!

If you pump the pedal or don't hold the clutch in for longer than you need to everything works like normal, right?

The RPMs dropping and vibrations is the hydraulic system not holding pressure and slowly disengaging the clutch. That sounds entirely like a clutch hydraulic system problem to me. I had the same issues before, I replaced both the slave and master at the same time.

You could try bleeding the system again, but if the pedal pressure seems fine that probably isn't the issue. It's just like bleeding brakes, open the bleeder at the slave cylinder and either 1. use a mighty vac to suck out the fluid while you add to the master cyl or 2. have someone pump the pedal and add to the master cyl until there are no bubbles and tighten the bleeder.

Did you use OEM parts? Aftermarket rebuilds could cause problems. I have an aftermarket rebuilt master cyl and slave and it's always felt a little wrong to me. Maybe you got a defective master cylinder? Start the car, hold the clutch in, and have someone watch the slave cyl to see if it starts to push the fork out slowly. If it does then you know the problem is somewhere between the pedal and slave cyl, which has to be within the hydraulic system.
