Abstract
A piston for a brake caliper of a disc brake constructed as a pot which is open at one end, having a longitudinal axis, a wall, and a piston head. The piston is supported in a cylinder of the brake caliper such that it can be moved along the longitudinal direction, and it can be placed against a brake pad in the region of the piston head by an axial contact surface. When the piston is subjected to pressure by a hydraulic fluid, the piston moves in the cylinder and presses the brake pad against a brake disc. A projection having a conical surface is provided on an inner surface of the piston head. A recess is provided, which is substantially at the same distance from the longitudinal axis as the projection on the inner surface of the piston head, on an outer surface of the piston head.
