Re: Check for fluid leaks
Could be one of the cylinders (clutch master or slave) has gone bad. Not a terribly expensive job. I think some folks neglect to flush the clutch system when doing on the brakes, and the seals can't handle the rusted cylinder bores. Just bled tons of rust flakes and air bubbles from our M3's clutch line last week. Prev. owner probably never had it done.
