Please help with my clutch
 

Okay so all of a sudden I start my car this morning and the clutch pedal is all loose... I pushed it down and it goes down like nothing. It wont cone back up wither so it wont let me put it in gear because it's fully depresses... the clutch fluid is fine, so I don't know what else it can be its a 88long supra 5 speed

check ur clutch master cylinder for a leak or air bubbles

yep, master cyl or slave. im thinking slave if the fluid is still topped up.

Jay, the clutch pedal will sit on the floor anytime it gets no pressure build-up. I've noticed this in many makes and models. You'll need to reach down and pull it back up.

If the system is sound, and it was just expelling an air bubble, the pedal should now be firm.

If there is still no pressure, try bleeding the clutch system. If that doesn't work, you probably have a bad master cylinder that cannot transfer pressure to the slave cylinder. This is based on your mention of plenty of fluid and no obvious leaks.

at the same time, ive had the slaves fill up the weather protection boot with fluid, and not leak. visually i couldnt tell anything was wrong, but had no pedal and still had enough fluid in the res. this happened on my 93 nissan altima.

The fluid level may also appear fine if you check it while the master cylinder is still pressed in. Prop the clutch pedal up and then check the fluid level. While you're on the floor check if the floor or the firewall (coming down from the cylinder) feel wet or oily.

agreed, +1

Thanks so much guys well it ended it up being a faulty slave cylinder I believe but the master was already old too so I replaced both now its good to go......... on a side note I have a question. Will my supra be able to pass smog with custom three inch exhaust if I put the cats back on?

The diameter of pipe doesn't affect the volume of air moving through the pipe at any given RPM (just pressure and velocity) and has nothing to do with the contents of the exhaust.

With that being said the I should pas as long as long as the cats are good
