A brake caliper includes an actuator, a moveable brake pad including a brake pad backplate having a generally planar portion, and a friction material secured to the brake pad backplate. The brake pad backplate is being generally arcuate in shape and defines a friction material outer radius and has a friction face for engagement with a brake disc. The brake pad defines a wear limit of the friction material at a wear limit plane that is parallel to the friction face. The brake pad backplate includes a first pad abutment to limit rotation of the brake pad in a first direction. The first pad abutment is defined on a first lug surface of a first lug projecting from the generally planar portion, and the first lug surface is at a radius larger than the friction material outer radius and is positioned on the friction face side of the wear limit plane. The brake caliper also includes a stationary brake pad and a frame having a housing region for receiving the actuator, a reaction side portion for receiving the stationary brake pad in an axially static manner, and a first bridge arm connecting the housing region to the reaction side portion. The actuator is operable to move the moveable brake pad towards the stationary brake pad. The first pad abutment engages a first bridge abutment on the first bridge arm to limit rotation of the brake pad in the first direction.
