DEVICE FOR DETECTING ABRASION OF BRAKE FOR VEHICLE

摘要

A device for detecting abrasion of a brake for a vehicle and capable of accurately and surely detecting a time of abrasion. The device comprises a plate (3) engaging an outer gear (2), a disk (4) engaging an inner gear (5), a piston (6) for bringing the plate (3) and the disk (4) into pressure contact with each other to brake a vehicle, a stroke sensor (26) for detecting an amount of displacement of the piston (6), operation detecting means (27) for detecting an operation of a brake, and calculating means (21) for calculating amounts of abrasion of the plate (3) and the disk (4).
