Claim 0:
1. An electro-hydraulic brake assembly comprising:
a hydraulic control unit (HCU) body including a top surface, a bottom surface opposite the top surface, a side surface, and a front surface, with the side surface and the front surface extending perpendicular to the top surface, the bottom surface, and to one another, the HCU body defining a pressure supply bore and a master cylinder bore;
a fluid reservoir disposed on the top surface of the HCU body;
an electronic control unit coupled to the front surface;
a primary piston slidably disposed in the master cylinder bore and configured to supply brake fluid to a wheel brake in response to pressing of a brake pedal; and
a pressure supply unit including a pressure supply piston disposed within the pressure supply bore, and a motor having a motor shaft configured to cause the pressure supply piston to translate linearly through the pressure supply bore;
wherein the master cylinder bore is defined in the side surface; and
wherein the motor is located on the bottom surface of the HCU body,
wherein the HCU body includes a generally rectangular portion defining the top surface, the bottom surface, the side surface, the front surface, and a rear surface disposed opposite the front surface;
wherein the HCU body further includes a protrusion extending outwardly from the rear surface and upwardly from the bottom surface; and
wherein the pressure supply bore is formed within the protrusion.
