<p>A lining wear sensor comprises a discrete multi-layered strip (9) of electrically conductive material which is stuck to the edge (6) of a friction pad (2) so that it wears with the pad with a consequent change in electrical resistance of its layer (11) of resistive material. This can be measured by suitable contacts to indicate the wear condition of the pad. When the resistive material has a large temperature coefficient of resistance, temperature changes in the strip (9), and in the friction material itself, can be monitored to provide an indication of the operating characteristics of the brake, for example whether the pad (2) is being applied evenly to the disc, or whether it is in permanent rubbing contact with the disc.</p> |
