Abstract:
1. A caliper brake comprising: a caliper housing that constitutes an exterior of the caliper brake and has one end on which a fork is formed and is bent; a brake cylinder that is mounted on a side of the caliper housing to face the fork and generates a brake force inside the brake cylinder using an oil pressure of a damping oil transmitted from a brake line; a piston that is mounted within the brake cylinder and pressurizes a brake disc between the piston and the fork using the brake force generated in the brake cylinder during braking; a pressurization rod part that is mounted within the piston on a common axis, extends in an axial direction when abrasion occurs in the fork and a frictional pad of the piston and increases a distance at which the piston pressurizes the brake disc and moves, to compensate for abrasion; and a return spring part that is disposed within the brake cylinder on the common axis to the pressurization rod part, is elastically compressed during brake, is elastically restored when brake is released such that the abrasion compensation rod part is returned to its original position before brake, wherein the return spring part includes: at least one return spring allowing the piston to return to its original position when the oil pressure is released; and a spring cage housing the at least one return spring engaged with the pressurization rod part in a rotating manner by an “L” shape hanging hook formed therein.
