ABSTRACT:
The present invention provides disc brake caliper assembly for braking a rotary disc brake of a vehicle, the disc brake caliper assembly having a mounting bracket, first and second brake shoes, and 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, wherein the mounting bracket has shoulders each spaced from a corresponding aperture, each aperture being positioned outwardly of its corresponding shoulder 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, and 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. The invention also provides an arrangement in which the pins are not subjected to the weight of the caliper housing or shoes, and reduces the size of the caliper assembly.
