Replacement of brake drums can be determined based on the following three methods: 1. Observe the thickness of the brake drum: When the thickness of the brake drum is reduced to only one-third, it needs to be replaced. 2. Listen for sounds after lightly applying the brakes: If there are abnormal noises when lightly braking, the brake drum needs to be replaced. 3. Observe the car's response after braking: If braking is delayed and the braking force deteriorates, the brake drum needs to be replaced. The method for replacing brake drums is as follows: 1. Lift the car and remove the tire. 2. Unscrew the fixing screws on the brake caliper and remove the brake caliper. 3. Remove the old brake drum and push back the brake caliper piston. 4. Clean the installation bracket of the brake disc and install the new brake drum.
