So I went to leave work last night and went to start the car, only when I pushed the clutch in, the pedal stayed on the floor. I pulled it out, popped the hood looked at the clutch master, just to realize that is was low. I topped it up then pumped the pedal and got some of it back. Now, the clutch is working, but the pedal doesn't rebound all the way like it did before. Could I have a blown clutch master and or slave? if so how difficult is it to fix?
