Jumped in the car this afternoon to head into town for lunch and today something strange happened, the bite point of the clutch which is normally near the middle was almost at the bottom of the pedal near the floor. The car still drives fine, but this has happened a few times and especially when pumped and engaged, like you would in moving traffic the pedal stays near the floor. However it will return with help from a foot behind the pedal. And then it works normally. Any ideas?
