Friction coefficient definition

Friction coefficient means the ratio between the tangential force and the normal force acting between the brake pad and the disc or the brake shoe and the drum. For a disc brake, the apparent friction coefficient value from the brake under testing is a function of braking torque, effective brake radius, and the piston area. The apparent coefficient of friction is a calculated (mathematical) value and is not directly measurable. Also referred to as "Brake effectiveness".
