My 2000 748s had soft rear brakes. I tried bleeding them, but had no luck getting a better pedal. I ended up replacing the master cylinder, brake line and caliper - basically the whole system - with new Ducati parts. I "bench bled" the master cylinder, installed the rear caliper and the new line. Now, despite getting fluid through the system with my power bleed pump, I can't get any pedal at all. I also tried removing the rear caliper from the mount and raising it up above the reservoir, but this didn't do it either. I get fluid bleeding through with the mitivac, but I cannot get any braking action. I've bled dozens of brakes on various bikes before and never encountered this issue. Everything has been replaced, so it should work fine. What am I missing? Thanks!
