Abstract
An electric brake has a master cylinder () including pistons () for rear and front brake circuits and an electric motor () for actuating the rear brake piston (). A feedback circuit provides a signal indicative of the fluid pressure supplied to the rear brake circuit and is operable in response to driver commanded braking force () to supply fluid pressure to the rear wheel brake circuit. A mechanical coupling () between the second piston and a brake pedal is responsive to driver applied brake pedal force to supply fluid pressure to the front wheel brake circuit. A fluid circuit () utilizes the fluid pressure supplied to the rear wheel brake circuit to augment driver applied brake pedal force thereby supplying power boosted fluid pressure to the front wheel brake circuit.
