Clutch Pedal Goes To The Floor With No Pressure

Clutch Pedal Fell To Floor, Then Fine?

It's a possible theory, of course, no way of really knowing - I personally wouldn't risk it - I hate being stuck somewhere for a $100 game. Incidentally, the parts guy Niello said this was the third cylinder he sold last week - he said this always happens in hot weather (it's been 102 in Sacramento and 100 at my house the last few days - maybe even warmer in my garage!)! By the way, the fluid was really dark and after siphoning off most of it with the turkey baster, there was a lot of black gunk at the bottom of the tank. It's so cramped working next to the firewall - every step was tricky - getting the clevis pin out; the nut on the cylinder closest to the steering column; the fluid line in the top of the master cylinder - every one of them is mean! Couldn't get a socket on anything other than the bottom MC nut - everything else was socket wrench with minimal turn each time. Going back up isn't much fun either - trying to get the fluid line back on was no joy so had to get the woman to push on the cylinder (with all her might, bless her) so I could start the nut inside!

Clutch Randomly Goes To The Floor Sometimes.

About a week ago I noticed that I had to depress my clutch pedal fully to change gears, when normally I only depress halfway to change gears. I felt the clutch pedal pressure coming back and it was easier to shift gears until last night. I was hauling *** trying to catch up to my buddy's RX-8 (that's another story) and noticed that at high speeds and revs I was losing pressure on my clutch pedal and I couldn't shift any gears until I slowed down.

The slave is a sealed unit, so the sudden loss of pressure due to fluid loss may be a remote, and if you don't see any fluid specks... most likely not. Remove the slave from the bell housing, take a look at the shift fork inside. with your palm on the push rod on the slave, providing counter pressure, have someone depress the clutch slightly, can you feel any resistance? while the slave is out, take the end of a socket wrench or extension bar, anything long and round, and place it in the cup on the shift fork ( where the slave would push) push forward on the fork...should be a ton of resistance...that means the clutch diaphragm fingers are still there. A throw bearing, if completely frozen, will squeal and rattle when the clutch is depressed, then be silent as a mouse when the clutch is released. My money is on the slave having a bad internal seal, and can't squeeze. BUT...there's a chance that when you went 8000rpm, you messed up a synch gear in your trans, and its little bits are screwing up other syncros. Without synchromesh you can shift but you have to have the right revs and it's still a little big to get it going

I hope this can help.
