What colour was the brake fluid that was bled out? Master cylinder
finally failed due to old fluid ?? Did you see bubbles at each
bleeder? On my bus, one caliper bleeder screw will allow air in
between threads; it appears as if there's a bunch of air in system
when there is not.
long shot:
someone pushed the brake pedal while callipers were off knuckle during
bearing job? Brake pedal traveled further than normal and internal
seal(s) was damaged?
I"m not trying to blame the mechanic here but in my limited
experience, with the callipers removed from steering knuckles, the
pistons shouldn't move. i.e. doing just bearings, when reinstalling
the caliper, the pads should slip right over the rotor.
