Shoe mounted disc brake caliper assembly

A disc brake caliper assembly for braking a rotary disc brake of a vehicle, the disc brake caliper assembly comprising a mounting bracket fixedly securable to the vehicle;

• first and second brake shoes, having integral brake pads of friction lining material, slidably mounted in and retained by the mounting bracket for selective movement relative thereto to bring the brake pads into frictional engagement with the rotary disc brake;
• a caliper housing mounted solely on the brake shoes and comprising a bridge section for extending across the outer periphery of the rotary disc brake, a first leg section extending from the bridge section and having the first brake shoe securably attached thereto by a first retainer spring, and a second leg section extending from the bridge section and having a selectively actuable piston slidably mounted therein, the second brake shoe being securably attached to the piston by a second retainer spring, selective actuation of the piston causing the selective movement of the brake shoes;
• wherein the mounting bracket has shoulders each spaced from a corresponding aperture, each aperture being positioned outwardly of its corresponding shoulders and having a removable pin mounted therein and extending therefrom, the shoulders, apertures and pins extending in a lengthwise direction substantially parallel to the bridge section of the caliper housing;
• wherein the mounting bracket also defines an abutment adjacent each shoulder;
• wherein each brake shoe has a leg portion extending from each end thereof in a lengthwise direction substantially perpendicular to the bridge section of the caliper housing such that each leg portion is retainable between a corresponding shoulder, pin and abutment on the mounting bracket to mount and retain the brake shoes in the mounting bracket, but to allow sliding movement of the brake shoes in a direction parallel to the lengthwise direction of the shoulders;
• and
• an anti-rattle spring for substantially preventing rattle of the caliper housing and brake shoes, said anti-rattle spring being fabricated from a sheet material and is substantially H-shaped with a center portion and first and second legs with the center portion being bent to define first and second abutment portions and a centrally positioned curve portion, the first abutment portion engages the caliper housing and the second abutment portion engages the mounting bracket, and the centrally positioned curved portion engages behind the removable pin to secure the anti-rattle spring.
