Losing my patience with this. Had a seized front right caliper, have done the following.
Replaced both front calipers with remanned units. New pads, hardware, everything.
Tried pedal bleed, didn't work.
Replaced brake master cylinder after the pedal bleed didn't work and I figured it was worth replacing after reading about how that can kill an older BMC. Unit was bench bled.
Borrowed motive power bleeder, left at 15PSI for 30 min, no leaks in system.
I've bled this system three times with the motive at 25PSI, have gone through 3 12oz bottles of DOT4. No bubbles anywhere. Pedal will seem ok in driveway, but as soon as I test on a back road, it goes to the floor and will still allow the car to roll a bit. Needed to engage the parking brake to get it to stop completely.
I know even if the booster was shot I'd still have working brakes, just without the assist. This feels like there's still massive air somewhere, just don't know what else to do to get it out...
