A disc brake assembly includes a brake pad, a pad retainer, a brake caliper, and a pad spring. The pad retainer has a planar region situated at a first radius that engages a planar region of the pad spring to restrain radial movement of the brake pad. The pad retainer is secured to an outboard side of the caliper at a second radius and has a crook adjacent to the planar region to allow the second radius to be less than the first radius. The pad spring has a rounded edge adjacent to the crook.
