Abstract

A brake caliper comprises a cylinder body, a base, a piston, an intermediate element, a ball body and a brake element. The base is disposed onto the cylinder body via a movable form. The piston is disposed onto the cylinder body via a movable form and comprises a positioning portion. The intermediate element is disposed between the base and the piston via a movable form and comprises a threaded portion. The ball body is disposed between the positioning portion of the piston and the threaded portion of the intermediate element via a movable form, and further, the intermediate element and the piston can move relatively via the ball body. The brake element is driven by the piston to lead a disk to be braked. When the intermediate element is driven to move by the base, the intermediate element and the piston move relatively via the ball body so as to lead the piston to move towards the brake element, thereby driving the brake element so as to lead the disk to be braked. The brake caliper is simple in structure and easy in manufacturing, and reduces production cost.
