Abstract
The present invention relates to a bicycle brake arm 1 used in a brake caliper apparatus. The brake arm 1 mounted to a bicycle frame F for pivotal movement about an axis X. A brake shoe mounting bracket 4 is likewise coupled to the bicycle frame F for pivotal movement about the axis X. In one embodiment, the brake arm 1 is formed with an arcuate recess 12 whose arcuate center coincides with the axis X. The brake shoe mounting bracket 4 has a first portion 4a formed with an arcuate contour, conforming to the contour of the recess 12, and the first portion 4a is slidably disposed within the recess 12. A bolt 9 extends through an elongated arcuate screw hole 8 formed in the first portion 4a and an aperture 4g formed in the brake arm 1. A brake shoe 5 is mounted to a position adjusting mechanism formed on the second portion 4b of the bracket 4. Loosening of the bolt 9 allows for easy adjustment of the clearance between the brake shoe 5 and a bicycle tire rim 6 independent of position adjustments of the shoe via the position adjusting mechanism formed on the second portion 4b of the bracket 4.
