A piston pump for a brake may include: a piston moved by rotation of a motor cam, and movably installed in a piston housing; a sleeve installed in a shape to cover an end of the piston, and having an inner space for storing brake oil moved from the piston; an airtight mounting part coupled to the end of the piston, and blocking brake oil from moving between the piston and the sleeve; a return spring having both sides contacted with the sleeve and the airtight mounting part, and elastically pressing the airtight mounting part toward the motor cam; an inlet ball pressed toward the piston by an inlet spring, and installed in contact with the airtight mounting part; and a check valve installed at a position facing the sleeve, and discharging brake oil to the outside of the sleeve when the pressure of the brake oil rises.
