Abstract
A hydraulic braking pressure control apparatus for an automotive vehicle includes a master cylinder mounted on a brake booster for applying a braking force, a master cylinder reservoir provided on the master cylinder for supplying hydraulic fluid to the master cylinder, and a solenoid valve body mounted on the master cylinder. The solenoid valve body includes a plurality of solenoid valves and a fluid circuit operatively connected to the master cylinder for generating a braking pressure to be supplied to wheel brake cylinders. A pump body is mounted on the master cylinder and includes a pump device for returning hydraulic fluid to the master cylinder and the solenoid valve body. A pump motor drives the pump device, with the pump motor being mounted on the master cylinder and being symmetrically disposed with respect to the solenoid valve body.
