What Causes the Squeaking Sound in Brakes?

[StellaAnn]

The reasons for squeaking sounds in brakes include: 1. Running-in of a new car, where the brake pads' break-in is a crucial part; 2. Newly replaced brake pads also require a break-in period to better integrate with the old disc, and the brakes may feel harder initially; 3. Tiny sand particles entering between the brake pads, causing noise due to friction; 4. Missing or damaged fixing screws of the brake disc; 5. Malfunction in the brake system. Brakes are mechanical devices that slow down the vehicle, also known as decelerators. The car's brake pedal is located under the steering wheel. Pressing the brake pedal activates the brake lever linkage, which transmits pressure to the brake shoes on the brake drum, clamping the brake disc to slow down or stop the vehicle.
