What Causes the Squeaking Sound When Applying Rear Drum Brakes?
1 Answers
Rear drum brakes making a squeaking sound when applied may indicate severely worn brake pads that need replacement. Below is relevant information about brakes: Drum Brakes: Inside the wheel hub, two semi-circular brake shoes are installed. Using the "lever principle," the brake shoes are pushed to make contact with the inner surface of the hub, creating sufficient friction to reduce the wheel's rotation speed and achieve braking. Disc Brakes: A brake caliper controls two brake pads to clamp onto the brake disc attached to the wheel. When the brake pads grip the disc, friction is generated between them to reduce the wheel's rotation speed, allowing the car to slow down or stop.
