Abstract: A low cost brake sensor incorporates a sensor portion extending through one of the rivet holes in the backing plate of the brake pad. A locking sleeve snaps onto the sensor portion and secures the sensor to the backing plate. Preferably, the locking sleeve has a lip which snaps into a groove in an outer periphery of a sensor portion. The present invention thus provides a relatively low cost and secure way for attaching the sensor to the brake pad. No modification of the lining or the backing plate is necessary.

Abstract: The shape of a lead wire for detecting the wear of a brake pad is improved to detect the limit height of a rib on a disk rotor, and wear limit of a lining of the brake pad. A probe is engaged in the outer peripheral portion of each of back plates of brake pads provided on both sides of a disk rotor and has a lead wire buried in the probe. The wire is curved to protrude a predetermined distance toward the disk rotor. The predetermined distance is larger than a predetermined maximum allowable height of an annular rib on the disk rotor at its outer peripheral portion.

Abstract: The invention relates to a brake pad (1) having a wear indicator (5). The brake pad (1) has a first bore (20) opening out into the braking face (4) of the friction lining (2), a second bore (22) opening out into the first bore (20) and into the edge (23) of the lining, and a slot (24) which extends between the first bore (20), the second bore (22), the edge (23), and the braking face (4). The indicator (5) comprises a pellet (6) adapted to the first bore (20), a sleeve (14) slidably mounted on the conductors (12a, 12b) of the indicator (5) and urged against the pellet (6) by a resilient sheath (16) that bears against the connection terminal (15) of the indicator (5). The diameter of the sleeve (14) is substantially equal to the diameter of the second bore (22). The slot (24) serves to pass the conductor wires (12a, 12b) during installation of the indicator (5) on the brake pad (1), after the sleeve (14) has been moved away from the pellet (6).

Abstract: A brake lining wear sensor includes a metal contact secured to a grounded brake lining support plate through a semiconductive ceramic bushing containing silicon carbide and silicon nitride which establishes an electrical resistance between the contact and the support plate so that the contact has a resistance to ground when the brake lining is not worn, but when the brake lining is worn and the contact touches a grounded brake rotor or drum, a short to ground occurs. The sensor is coupled by a lead wire to an indicator circuit which senses the resistance value in the circuit path to ground to determine whether the contact is connected to the indicator circuit and whether it is electrically grounded to the rotor. An indicator lamp comprises a tri-color LED to emit different colors signifying a normal condition, an open circuit, or a worn brake lining condition.

Abstract: A friction lining wear indicator for shoe-drum brakes comprising a sensor mounted on a brake shoe, which actuates an indicator when the thickness of a friction lining carried by a platform of the shoe for engagement with a drum is less than a predetermined value. In order to locate the sensor at the most effective position without machining the lining or fastening the sensor permanently to the shoe, the sensor is located by a mounting device located in a depression in an edge of the platform, and co-operates with the shoe to retain the sensor adjacent the lining. The mounting device comprises a plastics plug, or a resilient clip, and the retaining device is releasable. The sensor comprises a wire loop or a pressed insulation-coated metal strip, and may be integral with the mounting device. The sensor and the drum are connected in a circuit with the indicator which is actuated when the sensor touches the drum.

Abstract: A disc brake pad having an integral backing plate on its rear surface is provided with a removable wear indicator. An insertion hole for the indicator extends through the backing plate and into the pad for a distance equal to the length of the wear indicator. To prevent the wear indicator from being forced backward out of the hole during operation of the brake, a thin plate is placed over the backing plate and firmly clamped thereto, thereby blocking rearward movement of the indicator.
