Abstract
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.
Claims13
A disc brake assembly comprising:
- a brake caliper having an outboard side;
- a brake pad;
- a pad spring including a spring planar region and a rounded edge;
- and
- a pad retainer including a retainer planar region having a first radius for engagement with said spring planar region of the pad spring to restrain radial movement of the brake pad, wherein the pad retainer is secured to the outboard side of the brake caliper at a second radius that is less than the first radius, the pad retainer further including a crook adjacent to the retainer planar region of the pad retainer and the rounded edge of the pad spring.

A disc brake assembly comprising:
- a brake caliper having an outboard side;
- a brake pad;
- a pad spring including a spring planar region, a rounded edge, radially outwardly curved ends, and an aperture;
- a pad retainer including a retainer planar region having a first radius for engagement with said spring planar region of the pad spring to restrain radial movement of the brake pad, wherein the pad retainer is secured to the outboard side of the brake caliper at a second radius that is less than the first radius, and wherein the pad retainer further has a crook adjacent to the retainer planar region of the pad retainer and the rounded edge of the pad spring;
- and
- a backplate including complementary curved surfaces and a backplate protrusion, wherein the radially outwardly curved ends radially retain the pad spring on the backplate and the complementary curved surfaces abut the radially outwardly curved ends of the pad spring and wherein the backplate protrusion of the backplate is located in the aperture of the pad spring to prevent axial movement between the pad spring and the backplate.
