Just when I think I've finally fettered a plain old Combat new show stopper show up.
Trixie once had as good a factory brake as any, having to be careful how hard I pulled level rolling into garage or locked up on smooth cement to slide.
Fixed a master cylinder leak but not sure how. Bore shows a nick but not in path of pressure seal. Piston pitted by not where seals seal. Had greyish sludge under the outer seal like Al dust but could see obvious source of that much rubbing raw. Cleaned the bore and piston parts and dadded some Hylomar around the outer seal inner and outter contact areas and stuck it back and topped off and bleed till no hint of bubbles. Then tied lever back for couple hours. Got on it but still no whoa.
Last fling out was too much work not to speed up just going down steeps then it went away almost completely on panic grip. Thought it was old hose swelling under pressure. Indeed the new hose feels firmer in lever and hose not felt bulging but won't slow a walk pace up short. Brake clearner sprayed disc and pads in place w/o effect.
Caliper was flushed just before Empire rally when it had adequate brake but not good brake as prior. Lever must be pulled carefully or it squirts way up over tank. Ain't been in caliper in a few years but put in SS and new O-rings and would expect a stuck caliper to not release rather than not grip. That next place to open again.
No fork leaks to contaminate pad but 's next step before I run out of ideas. Have lever tired back for over night venting so will see if I can ride Labor day or not.
