ok ok . so to recap. i c clamp the cylinder. and then bleed the brakes? or do i c clamp the cylinder and put the brake shoes on, then bleed the brakes? i don't see how i can have the c clamps on after i put the shoes on? and is this recompressing the cylinder essential? what exactly does this do?, and the rubber nipple thing. is it at the top, left, bottom, right? is it pretty hard to miss?
