A pump for anti-lock brake systems which is constructed so that a piston (40), an inlet check valve (100), and an outlet check valve (200) are integrally assembled with each other and are mounted in a bore (3), thus enhancing an assembling efficiency and brake oil suction performance of the pump. In the pump, the piston (40) reciprocates by a motor (2), the inlet check valve (100) is provided at an end of the piston (40), and the outlet check valve (200) is mounted to a plug (50) which closes the bore of a modulator block (1). The piston (40) is set in a sleeve (60,70) while the inlet check valve (100) is mounted to the end of the piston (40), and the sleeve (60,70) is fitted into the plug (50) to which the outlet check valve (200) is mounted, so that the piston (40), the inlet check valve (100), and the outlet check valve (200) are integrally assembled. <IMAGE>
