Abstract
A vehicle brake shoe assembly having a brake shoe platform incorporating a plurality of extensions which project through the brake friction material matrix to the outer friction surface of the brake shoe assembly. Each extension is configured to cooperate with the brake friction material matrix to engage a surface of an opposing friction element, increasing the static and dynamic friction performance of the assembly beyond that achieved from the engagement of the brake friction material matrix and the surface of the opposing friction element alone.
Claims9
An improved brake shoe assembly having a cylindrically curved brake shoe platform defining a portion of a cylinder, an inner supporting surface and an outer supporting surface and a brake friction material matrix disposed on the outer supporting surface of the brake shoe platform, the brake friction material matrix defining a friction surface, wherein the improvement comprises:
- a plurality of extensions projecting from said brake shoe platform outer supporting surface through said brake friction material to said friction surface, and wherein each of said plurality of extensions terminates above said friction surface.
