Brake Pad
A friction material that presses against the rotor to slow the vehicle.

Brake pads are made of composite materials designed to generate friction while withstanding high temperatures. When hydraulic pressure pushes caliper pistons, pads clamp the rotor to reduce speed. Over time, pads wear down and must be replaced to maintain safety. Symptoms of wear include squealing, grinding, or longer stopping distances. Using quality pads matched to vehicle type ensures optimal braking performance and minimal dust. Regular inspection prevents rotor damage and maintains effective braking.
