PCT No. PCT/JP97/00844 Sec. 371 Date Sep. 18, 1998 Sec. 102(e) Date Sep. 18, 1998 PCT Filed Mar. 17, 1997 PCT Pub. No. WO97/35122 PCT Pub. Date Sep. 25, 1997The present invention is a device for detecting abrasion of a brake for a vehicle, and is capable of accurately and surely detecting a time of abrasion. For this purpose, the device includes plates (3) engaged in an outer gear (2); discs (4), engaged in an inner gear (5); a piston (6), for bringing the plates (3) and the discs (4) into pressure contact to thereby brake a vehicle, a stroke sensor (26), for detecting an amount of displacement of the piston (6); an operation detecting device (27), for detecting an operation of a brake; and a computing unit (21), for computing amounts of abrasion of the plates (3) and the discs (4) based on detection signals from the operation detecting device (27) and the stroke sensor (26).
