Clutch Master Cylinder question. 1989 Supra.
 

1989 Mk III non-turbo Toyota Supra. 180,000 miles.

The cylinder is leaking a lot of fluid, the clutch started to make grinding sounds, and it wouldn't start with the clutch pushed in; the car rolled forward. Somebody told me it was the clutch, but when I pumped the cylinder, the car moves forward and can do burnouts, and can be driven. When you start the car and try to put it in gear, it grinds, until you pump the clutch pedal.

Can anyone help me out, or give me some advice? Thanks in advance.

If it's leaking fluid, then you're getting air in the lines and losing fluid. These car's have hydraulic clutches, like your brakes.... Low fluid and/or air means it won't work right. Fix the problem you know of and see if that does it (sounds like it should).

I suggest you replace both the master and slave together. They work totally together, and wear together. If one is bad, the other is not far behind. This way, you don't have to worry or hassle with with the other later.

I replaced the clutch master and slave cylinder on my 1988 Supra. I was losing fluid, and the floor mats were getting wet. The slave cylinder was a snap. The master was a BEE-YOTCH. The master was held in by studs, and the nuts are under the dashboard, high-up, and in a corner. I had to do the outside nut totally by feel. I could not even see a glimmer of it. I'm glad I probably will never have to do this again.

I would suggest you give driftmotion a call, they seem to have decent stuff, they can get you master and slave cylinders, and the also have a nice stainless clutch line.

Good luck.

lol, sounds like me, when I put the 5spd in my Ranger the master cylinder was a pita, it didn't line up with the clutch pedal, which was another battle it self. I had to fab up a adapter so it would work. After that I said, never again!

Thanks a lot everyone, so far replacing the master cylinder has worked, though I'll definitely look into the slave as well. Thanks again!
