ABSTRACT:
A hydraulic caliper disk brake (10) according to the present invention includes a caliper base (46) that is supported by a folding triangular base (14) that generally includes a mounting base (30) and a support arm (54). The caliper base (46) is pinned to the mounting base (30) and the support arm (54) such that the caliper base (46) may pivot about the mounting base (30) when the pin connecting the support arm (54) to the mounting base is removed. The configuration allows the caliper assembly (12) to be pivoted out, away from a brake disk (16) such that the friction pads (142, 242) may be easily replaced. The caliper assembly (12) includes a self-activating wear adjuster (172) that functions to maintain a constant brake gap (174) between an active friction pad (142) and the brake disk (16). The caliper assembly (12) also includes a wear indicator in the form of a spring (134) that provides additional force that is fed back to the user when the friction pad (142) is significantly worn. The caliper assembly (12) further includes a manual adjustment member (220) that allows a user to adjust the position of the passive friction pad (242).
