A brake assembly of a vehicle for enduring corrosive road effects is disclosed. The brake assembly includes a mounting bracket having a bore. An anchor pin extends through the bore of the mounting bracket to rotatably support a brake shoe of the assembly. More specifically, the anchor pin includes first and second end portions and an outer surface, and the brake shoe rotates about the first and second end portions of the anchor pin relative to the mounting bracket. A rubber layer is disposed between the outer surface of the anchor pin and the bore of the mounting bracket to permit rotation of the brake shoe about the mounting bracket in the event the brake shoe becomes corrosively bonded to the pin. In such an event, a flexural stiffness of the rubber layer enables rotation of the anchor pin relative to the mounting bracket, and since the brake shoe is bonded to the anchor pin, the brake shoe also rotates relative to the mounting bracket thereby maintaining operation of the brake assembly.
