Automobile Brakes :: Friction Material

Two main types of friction materials are disc brake pads and drum brake lining. Braking force of every brake depends on the coefficient of friction (which in turn depends on friction material properties), and the force with which it is pressed against the friction surface.

Brake Lining

Brake Lining is the friction part of Drum Brake which will push the inside surface on brake drum to slow down or stop the car. The shape of the Lining is curve to meet the surface of the brake drum.

Disc Pad

Brake pads convert the kinetic energy of the car to thermal energy by friction. Two brake pads are assembled to the brake caliper with their friction surfaces facing the rotor.
