What Causes the Abnormal Noise When Braking with Rear Drum Brakes?
1 Answers
Here are the specific reasons for the abnormal noise when braking with rear drum brakes: 1. Oil contamination between the brake shoes and brake drum: Oil contamination between the brake shoes and brake drum of the drum brake causes slipping and produces a sharp sound. Clean the brake drum and brake shoes with alcohol to remove the oil contamination. 2. Overly smooth surface of the brake shoes: An overly smooth surface of the brake shoes in the drum brake causes slipping and produces a sharp sound. Sand the surface of the brake shoes with 800-grit sandpaper to increase their friction. 3. Severe wear of the rear brake drum: If abnormal wear is observed on the brake drum, it is recommended to replace it and then test drive to observe the results.
