I got in my car yesterday, went to dip the clutch (my drive way slopes upwards so i usually leave the car in first) and i couldn't push the pedal down...tried again with more force and it went down. I was in a bit of a rush so i started the car, rolled out back out of the drive, push the clutch down hard so i could get it into first and then it was fine after that. No problem at all while driving.
Later on i went to start her up again, same problem but it seams to be worse now. You cant push the clutch down with the usual amount of force, you have to push reeeaally hard.
It seams that its only limited to when the car is stopped or moving very slowly (first and reverse). You cant use clutch control now as the clutch is so stiff to push down, but when you're on the move gear changes are fine and the clutch feels normal.
Anybody have any idea what could be causing this? Any help will be very much appreciated.
