my clutch peddle is on the floor. The cable is fine, I followed the cable to this arm and I can move the arm up and down. When I do this the peddle goes back to the up postion. After reading some of the other posts i decided to take off the green end cap. The spring and everything else looks fine. Behind the green end cap there is a metal lever, this lever moves up and down when I pull on the cable. There is a piston or cylinder that looks like it is supposed to move this lever up and down. This piston is stuck in the down postion. My question is what is this piston or cylinder called, and how do I replace it?
Thanks
