ABSTRACT:
A brake pad wear probe contains a plurality of terminals turned or bent into a U-shape with their tip positions offset from each other. The terminals are cut in stages according to the wear development degree of the brake pad. The terminals define energization routes to electro-magnetic coils at relays, and the broken line state of the terminal can be detected at the respective relay by detection of a break in its corresponding energization route. As a result, electro-magnetic switches work in response to the wear development degree, turning on predetermined indicator lamps of a display to inform a driver of the brake wear condition.
