Abstract
A disc brake having an actuation mechanism, a disc brake rotor, first and second brake pad mounting structures, and first and second brake pads. The first and second mounting structures may have formations that affect fitting of the first and second pads.
Claims20
A disc brake comprising:
- an actuation mechanism;
- a brake rotor arranged to rotate about a rotational axis;
- inboard and outboard brake pad mounting structures to be located, in use, adjacent opposing inboard and outboard faces, respectively, of the brake rotor;
- and
- first and second brake pads located by the inboard and outboard brake pad mounting structures, respectively, wherein upon application of the actuation mechanism the first and second brake pads clamp the brake rotor and brake torque is reacted by the inboard and outboard brake pad mounting structures, wherein the inboard and outboard brake pad mounting structures comprise inboard and outboard abutment surfaces, respectively, that support the first and second brake pads in a radial direction;
- wherein to prevent or inhibit fitting of the first and second brake pads, individually or in combination with friction material facing away from the brake rotor, the inboard and outboard brake pad mounting structures include first and second protrusions, respectively, on radially inner faces thereof, wherein the first protrusion protrudes outboard and protrudes radially outward from the inboard brake pad mounting structure, and the second protrusion protrudes inboard and protrudes radially outward from the outboard brake pad mounting structure, and wherein the first and second protrusions do not have mirror symmetry about a plane defined by a center of the brake rotor and normal to the rotational axis of the brake rotor, and wherein the first and second protrusions are remote from the inboard and outboard abutment surfaces, respectively;
- wherein the first brake pad in a fully worn condition is successfully fittable on the inboard brake pad mounting structure with its friction material facing the brake rotor when the first protrusion is received in a first complimentary recess on the first brake pad;
- and
- wherein there is a spacing axially between the brake rotor and an outboard face of the first protrusion when the brake rotor is in a fully worn condition, and wherein the first brake pad in the fully worn condition is not insertable between the first protrusion and the brake rotor in the fully worn condition.
