Rear brakes, because the rear carries more braking load
Front brakes, because the front brakes do most of the braking work
They wear evenly, because of the proportioning valve

Caliper piston seized
Parking brake out of adjustment
Faulty power booster
A car with 4 wheel disc brakes has a brake squeal
