ABSTRACT:
A brake shoe for bicycles having a shoe holder provided with a connecting rod on its back, and a shoe block held at its base portion to the shoe holder. The braking face of the shoe block is formed with a projection serving as a gauge for positioning the braking face at an appropriate angle with the rim surface of the wheel. When the brake shoe is to be attached to a brake arm, the brake shoe is so positioned that two points of the shoe block, i.e., one point of the braking face and the projection, are in contact with the rim surface, and the brake shoe in this state is fixed to the brake arm. The brake shoe thus positioned is operable optimally as contemplated by the designer. When the brake is actuated, the projection is readily collapsed without producing any adverse effect on the braking function and removed early by friction.
