Another thing that anyone bleeding brakes should be aware of is NOT to stroke the pedal such that the piston bottoms-out in the MC.
Bench bleeding has NOTHING to do with brake shoes. The process is intended ONLY to completely void the circuitry within the MC of any air.

How much pressure is being is being exerted on the wheel cylinder when the bleeder is open and the brake pedal goes to the floor?
