connector 14 for an electronic and or fluid pressure signal from a sensor 28 connected to a vehicle brake pedal 30 the sensor 28 senses a deflection of the pedal 30 into a first deflection zone 32 caused by a force 34 on the pedal 30 and provides a signal 36 to the controller 12 regarding the deflection the controller 12 uses the signal 36 from the vehicle brake pedal sensor 28 and the signal 26 from the accelerator sensor 18 to generate at least one signal 38 to at least one service brake valve 40 typically the signal 38 leaves the controller 12 through one of the output connectors 16 by way of example only the controller 12 can also provide one or more signals to other braking devices and or the engine not shown the signal s can be communicated to the service brake valve 40 and or anywhere else electronically and or through fluid pressure means the service brake valve 40 is in fluid communication with a supply reservoir 42 of brake fluid 44 a pump 46 draws the brake fluid from the supply reservoir 42 and pressurizes it within a brake line 48 a brake fluid pressure regulator 50 is located within the brake line 48 for electronically and or mechanically regulating the brake fluid pressure as needed a first accumulator 52 is in fluid communication with the brake line 48 to receive and store brake fluid under pressure a one way valve 54 upstream from the first accumulator 52 prevents brake fluid from returning to the fluid supply 42 and maintains fluid pressure downstream.
