While on my way to take car to car wash the clutch pedal crunched to the floor.There was bits of plastic on footwell.I checked and noticed the rod had come out of pedal and plasic stop had snapped. I replaced parts (what a pain of a job!) and once put pedal down the plastic back plate came off again.there seems to be no play in the master cylinder?,it seems to have siezed.Any help would be greatly apreciated before i buy anymore parts.
