Abstract
A vehicle brake assembly of the kind comprises actuating means (6) for applying the brake linings (4, 5) to a brake rotor (1), adjusting means (13) adapted to be driven by the actuating means (6) for the purpose of maintaining the brake linings (4, 5) in close proximity to the brake rotor (1), and wear sensing means (60) responsive to actuation movement of the brake in a brake-applying direction. The wear sensing means (60) comprises a sensor (101) adapted to be operated by movement of an operating member (102) in a linear direction, a rotatable follower member (106) responsive to movement of the adjusting means (6), and a transmission mechanism (104) for translating rotary movement of the follower member (106) into linear movement of the operating member (102). The brake includes re-set means for resetting the relationship between a datum for the sensing means (60) and the brake during servicing of the brake. The re-set means may comprise means for adjusting the effective length of the operating member (107).
