What Causes the Squeaking Sound of Brakes?

[DelAriana]

Brake squeaking occurs due to excessive friction between the brake pads and brake discs, issues with the brake pad material, or it might be because the brake pads are newly replaced and require a break-in period for proper adaptation. The working principle of brakes involves converting the kinetic energy of a moving vehicle into frictional heat energy to dissipate it. Common automotive braking systems include drum brakes and disc brakes. Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, and other transport machinery. The general principle of braking involves fixing a wheel or disc on the high-speed shaft of the machine and installing corresponding brake shoes, bands, or discs on the machine base to generate braking torque under external force.
