hi my clutch master cylinder located on top of my clutch pedal is leaking fluid. so i decided to take off the clutch master cylinder and try to fix it , i think i just need a repair kit to seal it off. can anyone tell me step by step how to install the repair kit. from what i know i will replace the rubber parts. but my question .. there is a screw located in the middle of the cylinder , if i remove it will i just rescrew it or do i need to do something elso like press the piston then rescrew it. i think the screw is a lock for the piston. anyway just let me know step by step how to install the repair kit thanks
