  • Patent number: 11959522
    Abstract: A brake assembly having a brake carrier, a caliper, first and second brake pads, a pad retraction spring, and a first stop surface. The pad retraction spring urges the first and second brake pads in a direction away from a rotor plane. A first supporting portion of the pad retraction spring is configured to abut the first stop surface to inhibit the pad retraction spring from entering a partially enclosed volume.
    Type: Grant

  • Patent number: 11879511
    Abstract: A disc brake assembly having brake pads, a brake carrier, a caliper, and an actuating arrangement. The caliper is slidable with respect to the brake carrier for clamping and release of a rotor by the brake pads. The actuating arrangement is configured to selectively move the caliper and the brake carrier relative to each other generally transverse to a first longitudinal axis so as to lock or inhibit sliding of the caliper relative to the carrier.

  • Publication number: 20230105818
    Abstract: A drum brake assembly that includes a brake drum, first and second brake shoes, a cam shaft, a first tappet, a second tappet, and a wear adjuster mechanism. The wear adjuster mechanism has a cross shaft and a sensor. The sensor is configured to detect rotation of the cross shaft about a longitudinal axis to monitor wear of the first and second brake shoes and a braking surface of the brake drum.

  • Patent number: 11603896
    Abstract: A caliper guide assembly and a method of manufacture. The guide assembly may include a guide pin, a guide bore arranged to receive the guide pin and permit relative axial sliding thereof, a bush arranged to define at least part of the guide bore, and a sensor arrangement configured to provide an output indicative of a state of wear of the bush.
