There are times when free play happens within the caliper, a part of the disc brake. This is a result of rapid vibration taking place on the brake pad which will eventually make the pad produce a screeching sound that can be irritating to the ear.
Contact between Two Brake Disc Parts
The scraping noise also happens when the rotor disc comes in contact with the caliper. Like with rapid vibration, the reason for this contact is due to the extreme wearing out of the brake pads. Sometimes, the rotor is affected by the pad's wear and tear which makes the noise even louder than usual.
Rear Drums and Drum Brakes Pressing Each other
A thumping noise made by the vehicle when brake is applied can result from when the drum brakes press inside the metal drum.
