System and method for monitoring wear of braking frictional pad of motor vehicle

A system for monitoring wear of a braking frictional pad of a motor vehicle, the motor vehicle comprising a hydraulic brake device acting on a vehicle wheel thereof, the hydraulic brake device having a brake disc rotatable together with the vehicle wheel and a braking frictional pad configured to be non-rotatable relative to the vehicle wheel and be linearly movable parallel to a rotational axis of the vehicle wheel, the system comprising:

• a record module configured to record a time required by the hydraulic brake device for establishing a brake hydraulic pressure when the motor vehicle is parked;
• and
• an electrical control unit in data communication with the record module and configured to compare the time required by the hydraulic brake device for establishing the brake hydraulic pressure with a time required by the same hydraulic brake device for establishing the brake hydraulic pressure and recorded when the braking frictional pad is a brand new one, so as to determine the wear state of the braking frictional pad.
