My SMC had developed a small fluid weep from around the boot/clevis area, not major but enough to dribble down the bracket and a few droplets on the leading edge of the fairing. I happened to have a spare piston assembly, so I pulled the circlip out, removed the old parts, visually checked the bore for marks and found none, and proceeded to reinstall the new/old piston, circlip, boot and clevis. So far so good, but bleeding hasn't been fun. I have followed the manual, and bled the front centres first, then the PCV, the rear centre and finally the rear outer. Problem is the SMC does not seem to hold any pressure; when the bike is parked I can stroke the SMC fully with little resistance. With the pedal pressed, there is SMC pressure. While riding, the pedal itself is inconsistent, will feel firm on one application, then needs a little pump up for the next. Is this a bleeding problem? I have been working on my own so not able to simultaneously press the pedal, SMC and bleeder (although I do have a speed-bleeder which has been good). Suggestions welcome.
