Hongyu Break Pads

The brake pads convert the kinetic energy of the car into heat by friction. The brake calipers contain two brake pads whose friction surfaces face the rotor. When the brake is hydraulically applied, the caliper clamps or squeezes the two gaskets into the rotary rotor to slow down / stop the vehicle. When the brakes are heated by contact with the rotor, it transfers a small amount of friction material onto the disc to make it gray. Brake pads and discs then “stick” to each other to provide friction to prevent the vehicle.
