An electro-hydraulic control unit for a vehicle brake system includes a hydraulic control unit including an HCU block (32) defining a motor bore (40) containing an electric motor (42) and an eccentric chamber (50) containing a rotating eccentric (52) driven by the electric motor. The HCU block also defines a pump bore (66) containing a piston pump (68) including a piston rod (80) having a generally cylindrical shape with a smooth exterior surface extending substantially its entire length. An end cap (86) is press fit around an end of the piston rod (80) and includes a flange portion (108) extending annularly outwardly for engaging a return spring (94). A piston guide (90) includes a tubular portion (96) guiding the piston rod and a shoulder (92) for engaging the return spring (94). A throat (112) of the piston guide (90) holds a gland seal (120) surrounding the piston rod. An outlet valve housing (130) includes a tubular protrusion (138) extending into the throat (112) of the piston guide to hold the gland seal (120).
