Whhat type of clip is used to attach PM piston to brake pedal? Is it a C-clip or is it like one of those round type clips that connects the throttle cable. I can't see the clip but can feel it, it's round/concave do you slip a screw driver under it between the pedal and clip and work it out,or use a pair of needle nose pliers and grab , twist and pull. Never have taken one of these off, can't see it know it's there though. Any help or suggestions would be much appreciated. TIA
