Disclosed is an invention for a vehicle brake apparatus. The disclosed vehicle brake apparatus comprises: a brake pad pressing a brake disc; a screw bar positioned inside a caliper body and rotated by receiving a power from a motor unit; a spindle unit which is linearly moved by rotation of the screw bar and is coupled to the brake pad; a piston unit coupled to the spindle unit in a shape surrounding the outside of the spindle unit, made of a material having a hardness lower than the same of the spindle unit, and moving together with the spindle unit; and a sealing unit installed on the caliper body and in contact with the piston unit. An objective of the present invention is to provide the vehicle brake apparatus capable of preventing drag torque from being induced.
