The clutch on my '97 m3 with 80k miles engauges just off the floor. I thought it's supposed to release shortly after it's pressed, towards the top. Is this correct? There doesn't appear to be any leakage from the master or slave cylinder and the clutch isn't slipping so I don't think it's worn down that much. Is there a relatively common problem with the system or suggestions on what to replace? Thanks.
