Abstract:
A disc brake for engaging a rotor, comprising:a support member defining a pair of guide sleeves;a caliper moveable with respect to the support member;a main guide pin and a sub-guide pin attached to the caliper and inserted into respective ones of the guide sleeves to guide the caliper with respect to the support member;an outer pad having a back plate, the back plate in contact with the caliper; andfirst and second protrusions defined in a surface of one of the caliper and the back plate to respectively engage first and second recesses defined in a surface of the other one of the caliper and the back plate, the first protrusion and the first recess being disposed on a run-out side of the disc brake, wherein a brake torque applied to the outer pad is transmitted by the first protrusion and the first recess,wherein the main guide pin, the sub-guide pin, and the guide sleeves are astride the rotor such that portions of each of the main guide pin, the sub-guide pin and the guide sleeves each cross a plane defined by a surface of the rotor facing the outer pad, andwherein a contact portion of the main guide pin in contact with the respective one of the guide sleeves is astride the rotor such that the contact portion crosses the plane defined by the surface of the rotor facing the outer pad.
