A brake piston provided in a brake system of a vehicle and pressing a brake pad to a disc by braking hydraulic pressure, the brake piston comprising:
- a body portion installed in a cylinder provided in a caliper housing, being in a shape of a pillar, and configured to be movable forward and backward,
- wherein the body portion comprises:
- a first body portion provided at an outer side of the body portion in a radial direction of the disc;
- and
- a second body portion provided at an inner side of the body portion in the radial direction of the disc and having a coefficient of elasticity that is different from a coefficient of elasticity of the first body portion.
A brake system comprising:
- a carrier in which a pair of brake pads are installed to be movable forward and backward;
- a caliper housing slidably installed in the carrier, wherein a cylinder is provided in the caliper housing;
- and
- a piston installed in the cylinder and configured to be movable forward and backward,
- wherein the piston comprises a body portion being in a shape of a pillar, and
- the body portion comprises:
- a first body portion provided at an outer side of the body portion in a radial direction of the disc;
- and
- a second body portion provided at an inner side of the body portion in the radial direction of the disc and having a coefficient of elasticity that is different from a coefficient of elasticity of the first body portion.
