Abstract
A method and a system for monitoring wear of a braking frictional pad of a motor vehicle, includes stopping the motor vehicle stably on a horizontal or substantially horizontal plane; determining a current fluid level in a brake fluid reservoir; determining a volume difference (ΔVL) of the brake fluid in the brake fluid reservoir by comparing the determined current fluid level with a predetermined reference fluid level; when a thickness loss of a braking frictional pad equipped for a front vehicle wheel or a rear vehicle wheel is known, determining a thickness loss of a braking frictional pad assigned for the other front vehicle wheel or the other rear vehicle wheel based on the volume difference of the brake fluid in the brake fluid reservoir and a diameter of a brake piston of the respective brake device.
