Yesterday after driving for 10 minutes and stopped at an off-ramp, my clutch pedal was stuck in the up position. I managed to re-start the car in 1st and make it home that way. The reservoir is very low and I find that the release fork snapped off, too. I don't know if the seized hydraulics or the fork came first. I rebuilt the master cylinder about a year ago. Any thoughts on the cause of seizing & the broken fork? I'm guessing I should rebuild the slave. How tough is it to get into the pressure plate area?
