Abstract: A wear detector in a brake pad is disclosed including a projection on the face of the detector extending substantially perpendicular thereto. A U-shaped signal wire is bent around the projection and spaced apart therefrom so that, when the wire is rendered discontinuous by abrasion of the brake pad, the detector body is not damaged and a signal is activated, thereby indicating that a replacement of the brake pad is required.

Abstract: The invention relates to an assembly comprising a friction pad (A), a spring (B) and a wear indicator (C) for a motor vehicle disc brake. The friction pad (A) includes a carrier plate (10) received with anchorage and sliding in a torque-withstanding member (16) of the disc brake, a friction lining (12) being fixed to a part of the surface of a first face of the carrier plate (10) to enter into frictional contact with a rotating disc (22) when a force is applied to a second face of the carrier plate (10) opposite the first face. A through-opening (24) is formed in the carrier plate (10) for fixing a helical part (30) of the spring (B), this part being formed of at least one turn of metal wire and of a fitting part (46) of the wear indicator (C) of the friction lining (12) passing through the helical part (30) of the spring (B). According to the invention, the spring (B) includes end parts (32, 34) situated on either side of the carrier plate (10), the helical part (30) of the spring (B) being received in the opening (24) of the carrier plate (10), and the fitting part (46) of the wear indicator (C) being formed with a screw thread interacting with the helical part (30) of the spring (B).

Abstract: A wear-detection probe for a brake lining material comprises: a detection conductor which-extends a given length toward the rotor from the side of the brake lining material facing away from the rotor; a probe body housing supporting the detection conductor; a probe connector housing detachably connected to tile probe body housing; and a pair of terminals supported in the probe connector housing, the terminals contacting the detection conductor when the probe connector housing is connected to the probe body housing. The conductor either contacts the rotor or is cut off by the rotor when a predetermined thickness remains in the brake lining material due to wear. Since it is possible to exchange probes without exchanging harnesses, the cost for replacing the probe is greatly reduced.

Abstract: A brake apparatus having a friction pad riveted to a brake shoe and a light conductor extending through the pad within its working thickness. As the pad is worn away, the light conductor is severed by the abrasive action of a rotatable member causing a remote indicator, responsive to the interruption of light transmission through the conduit, to signal the need to replace the pad. The configuration of the light conduit insures that the signal will be given at the appropriate time despite misalignment between the pad and the rotatable member.

Abstract: An electrical contact is embedded in an insulator which, in turn, is fitted onto the disk side of the backing plate on a disk pad. When the pad wears excessively the insulator is worn away and the contact abuts the disk so that an alarm signal may be generated. Further wear will cause the disk to abrade and break the contact. The contact assembly is compact and enters the brake assembly through a vent hole which is typically provided therein.

Abstract: Herein disclosed is a resilient structure for use in a disc brake of the type including an electric wire having its looped end extending in the brake lining from the rear side thereof with a predetermined distance, and detecting means feeding an electric current to the electric wire for detecting disconnection at the looped end to indicate that the brake lining is worn out to exceed the working limit of the disc brake. The resilient structure includes a guide member pressor extending circumferentially of the brake disc and resiliently engaged with the guide member of the disc brake for applying a thrust to the latter, and a resilient arm extending from the guide member pressor and engaged with the electric wire for applying a tension to the same to ensure said disconnection. The resilient structure may be made of a simple spring wire, and biases the friction pad so as to prevent undesirable noises which might otherwise be produced at the frictional engagement between the friction pad and the brake disc.

Abstract: A probe carried in a brake shoe is responsive to the temperature of the lining material and is also responsive to wear of the lining material in excess of a predetermined amount. The probe includes a housing in thermal communication with the lining material and in electrical communication with the rounded brake shoe backing plate. A loop of wire is carried in the probe and is connected to an indicating device in the operator''s compartment of the vehicle through an appropriate control device. When the friction material has worn a predetermined amount, the wire loop is brought into engagement with the member to be braked, thereby actuating the indicating device only while the brake is applied. Subsequent wear of the lining material severs the wire loop to actuate the indicating device at all times while the vehicle''s ignition is on. One end of a bi-metallic metal strip is secured to the housing and the other end of the bi-metallic strip is spaced a predetermined distance from a terminal affixed to the wire loop. As the temperature of the brake lining increases, the other end of the bi-metallic strip is brought into engagement with the terminal, thereby providing an electrical circuit between the wire loop and the grounded brake shoe backing plate, thereby actuating the indicating device.
