Abstract: A brake housing assembly including a brake housing and a bearing support. The brake housing may have a recess defining a recess axis, the recess having a base and a recess wall, the base defining a base contour. The bearing support may have a projection defining a bearing support axis, the projection having an end and a projection wall, the end defining an end contour corresponding to the base contour such that with the end in engagement with the base the end contour and base contour cooperate to align the bearing support axis with the recess axis.

Abstract: An adjuster mechanism for a disc brake. The adjuster mechanism may include an outer piston and an inner piston. The outer piston may define a bore having a female thread, a non-threaded region, and a transition region. The non-threaded region may have a greater diameter than a minor diameter of the female thread. The minor diameter of the female thread in the transition region may progressively increase until it meets a major diameter of the female thread.

Abstract: A brake pad, a disc brake, and a method of fitting a brake pad. At least one of a first brake pad and a second brake pad and corresponding support structures may have complementary profiles on circumferential faces thereof arranged so as to permit the brake pad to be inserted into a corresponding support structure in a transverse direction of the brake pad and at an angle to a circumferential direction of the support structure.
