Braking lining wear system

摘要

A braking system (10; 50) comprises a braking member (12; 52) mounted so that an engagement surface (12c) of the braking member can engage a braked member (14) to apply a braking force thereto. The braking system also comprises a wear sensor (20; 60) operable to detect wear of the braking member in service. The wear sensor comprises a sensor head (22) mounted so that a wear surface (22c) of the sensor head is substantially flush with the engagement surface (12c) of the braking member (12) and engages the braked member (14) when said engagement surface does so that said engagement and wear surfaces are subject to substantially equal wear. The wear sensor also comprises detecting means (30) operable to detect wear of said sensor head (22).
