ABSTRACT:
A hybrid brake apparatus for a vehicle includes a hydraulic brake circuit having a first fluid circuit and a second fluid circuit connected to a master cylinder for generating hydraulic pressure in the first and a second fluid circuits, and electrically actuated brake elements controllable as a function of the hydraulic pressure in one or the other of the first and second fluid circuits. The apparatus may include a pedal feel emulator in one of the fluid circuits. The apparatus may also include a booster for amplifying pressure in the fluid circuits, a sensor for determining that the booster has failed, and control elements providing compensation for the failed booster during operation of the electrically actuated brakes while the booster is inoperative.
