How to Remove a Car Brake Drum?

Steps for removing a car brake drum: 1. Before removal, use a screwdriver to press the wedge upward through the wheel's bolt hole to retract the brake shoes; 2. Use a specialized tool to remove the hub cover, pull out the cotter pin, and remove the crown nut retaining ring; 3. Remove the hub bearing preload adjustment nut, washer, and bearing, then take off the brake drum. Drum brakes consist of rotating parts, fixed parts, actuating parts, and positioning adjustment devices. Drum brakes have a shape similar to a cast iron hand drum, known as the brake drum. Disc brakes offer better responsiveness, stability, and heat dissipation.
Remember when I changed the rear brakes last time, it wasn't as complicated as imagined. First, fully release the handbrake, otherwise the drum won't come off. Use a jack to securely lift the car, remove the wheel, and you'll see the round drum cover. Some cars have a small screw in the middle securing it, which needs to be removed with the right screwdriver. If it's badly rusted, don't force it; gently tap around the edges with a rubber mallet to loosen it. For particularly stubborn ones, spray rust remover on the seams and wait ten minutes, then pull firmly from both sides. When removing, it's best to lay a cloth under the chassis to catch falling brake dust, as inhaling it isn't good for your health. Before installing the new drum, don't forget to clean out the brake pad debris inside.
