Abstract
A brake apparatus and method utilize an electric power brake booster for operating a push rod actuated hydraulic master cylinder. The existing vehicle electrical system provides electric power for the power brake booster, thus eliminating the need for engine driven or auxiliary pressure/vacuum sources. The electric power brake booster includes an electrically powered actuator having an output shaft adapted for operative connection to the master cylinder, and an input for receipt of a signal indicative of force applied to the push rod. The electrically powered actuator augments the force applied to the push rod in response to the signal indicative of the force applied to the push rod. The booster may include a sensor for sensing force applied to the push rod and generating the signal indicative of the force applied to the push rod.
