1. Worn brake pads: Brake pads are designed to wear down over time, and when they get too thin, they can start to make a thumping noise when you brake. This is because the brake pads are no longer able to absorb the impact of the brake caliper against the rotor, and the noise is caused by the metal-on-metal contact.
2. Loose or damaged brake caliper: If the brake caliper is loose or damaged, it can cause the brake pads to move around and make a thumping noise. This can also be caused by a bent or damaged brake rotor.
3. Faulty brake booster: The brake booster is a vacuum-powered device that helps to amplify the force you apply to the brake pedal. If the brake booster is faulty, it can cause the brakes to make a thumping noise.
4. Damaged wheel bearing: A damaged wheel bearing can also cause a thumping noise, especially when you turn the steering wheel. This is because the wheel bearing is responsible for keeping the wheel hub in place, and when it is damaged, it can cause the wheel to move around and make a thumping noise.
