Abstract
A caliper brake is disclosed. According to an aspect of the present disclosure, the caliper brake may include: a carrier installed so that a pair of pad plates are movable toward and away from a disk side; a caliper housing slidably provided on the carrier and including a cylinder, a first piston installed in the cylinder and provided to be movable toward and away from the pad plates by hydraulic brake pressure; a second piston installed in the first piston and provided to be movable toward and away from the pad plates by hydraulic brake pressure; and a power-conversion unit installed through the cylinder and pressurizing the second piston by receiving driving power from an actuator.

A caliper brake, comprising:
- a carrier on which a pair of pad plates are installed to be movable toward or away from a disc;
- a caliper housing that is slidably installed in the carrier and is provided with a cylinder;
- a first piston that is installed in the cylinder and provided to be movable toward or away from the pad plates by hydraulic brake pressure;
- a second piston that is installed in the first piston and provided to be movable toward or away from the pad plates by the hydraulic brake pressure;
- and
- a power conversion unit that is installed to penetrate through the cylinder and receives driving force from an actuator to move the second piston forward and backward.
A caliper brake, comprising:

- a caliper housing that is slidably installed in the carrier and is provided with a cylinder;
- a piston that is installed in the cylinder and provided to be movable toward or away from the pad plates by hydraulic brake pressure;
- a power conversion unit that is installed to penetrate through the cylinder and receives driving force from an actuator to move the piston forward and backward;
- and
- a hydraulic supply unit that is provided with the cylinder and a passage so that a fluid inside the cylinder flows in and out, generates the hydraulic brake pressure inside a hydraulic chamber of the cylinder during a parking brake, and releases the hydraulic brake pressure inside the hydraulic chamber when the parking brake is released,
- wherein the hydraulic supply unit blocks a transmission of hydraulic pressure through the passage so that additional hydraulic brake pressure is generated inside the hydraulic chamber for a preset time when the parking brake is released.
