In an internal drum brake, friction material contacting the drum is called what?

Explanation:
In an internal drum brake, the surface that actually makes contact and creates the stopping friction with the drum is the brake lining. This is the friction material bonded to the brake shoe. The brake shoe itself is the backing structure that carries this lining and presses it against the drum when the brake is applied. Brake pads are used in disc brakes, not drum brakes, and while “friction material” describes the material itself, the standard term for the component that contacts the drum is brake lining.
