A: To remove the rear brake drum, lift the car's rear, support with jackstands, remove the wheel, ensure parking brake is off, and adjust the brake if needed. If stuck, tap the drum with a hammer. To install, reverse the removal steps and adjust brakes afterward. Check the drum for cracks or scores. Light scores can be smoothed with emery cloth; if deep, turn the drum but not beyond 0.060 in. (1.5mm).
