Abstract
A method and a system for monitoring wear of a braking frictional pad of a motor vehicle, the motor vehicle including a brake device acting on a vehicle wheel, the brake device including a braking frictional pad that is non-rotatable relative to the vehicle wheel and is linearly movable parallel to a rotational axis of the vehicle wheel; a brake piston configured to drive the braking frictional pad; and an electric parking brake or an electric mechanical brake, the electric parking brake or the electric mechanical brake having a drive motor and a piston driving part driven by the drive motor to be linearly movable, the piston driving part being configured to, when the motor vehicle is braking, drive the brake piston to contact the braking frictional pad and in turn drive the braking frictional pad to move.
