Quoting Rausch:
So, no fluid leaks? If it was sudden, I'd suspect the hydraulic system first. (Leaking slave, etc). If you pump the pedal a few times, do the symptoms change? Fluid level still where it's supposed to be?
Mine was all of a sudden, I drove in town 2 days before I loaded it on a trailer and moved out here. Drove it once in town here no problems but it was when I was leaving a friends that it acted up on me.... I replaced the slave bled the clutch... it was all fluid never was I getting any air out of it while bleeding it up here..... I need this fixed so I can actually drive it for a bit this year instead of 2 days like all last year....
