So, here's what I "think" is suppose to happen.
I believe my problem with bleeding the system with the new cup shaped seal is that with air in the system there would not be enough hydraullic suction to fold the cup over and draw fresh fluied from the reservoir. The only logical (to me) way to fill the entire system with fluied is to open the bleeder screw then push fluied down from the reservoir side thus folding the cup down allowing fluied to pass the seal. What I tried, unsuccessfully, was to pressure feed fluied up the system from the caliper bleeder towards the master, this would only "lock" the cup in place this preventing fluied from passing.,
Anyone? Anyone? Bueller?
