I was driving to bring my friend home and my Clutch pedal loses a lot of pressure. I have to press the clutch all the way to the floor for I to engage. What the hell cause this? Drive a 94 rs

 

check to see if your topped off with brake fluid, that happened to me and that was the problem

 

I'd start by inspecting for leaks and bleeding the system with new fluid since it'll only put you out a few bucks.

If that doesn't work, it could be a bad master cylinder, slave cylinder, maybe pressure plate?

 

Check for any leaks from your slave cylinder and clutch master cylinder. Typically, the clutch/brake fluid for the clutch reservoir wouldn't go down unless there is a leak somewhere. Make sure your clutch reservoir (or whatever it's called) is full.
