1. A system for controlling one or more brakes of a vehicle comprising:
a processor; and
a memory in communication with the processor and having a brake control module, the brake control module having instructions that, when executed by the processor, cause the processor to:
control the one or more brakes of the vehicle when the vehicle is in a first mode using a brake-by-wire system by selectively providing a first pressure to the one or more brakes from the brake-by-wire system via a shuttle valve, and
control the brake-by-wire system such that the one or more brakes of the vehicle are controlled using a mechanical braking system when the vehicle is in a second mode by reducing the first pressure such that a second pressure is provided via the shuttle valve to the one or more brakes from a master cylinder that is in mechanical communication with a brake pedal.
