Abstract
Braking system includes a brake, first valve that actuates the brake based on user input, second valve configured to selectively actuate the brake, and valve actuation system including a user input device moveable between first and second positions. A brake sensor provides a signal indicative of actuation of the first valve. The valve actuation system activates the second valve if the user input device is in the first position and the first valve engaged, retaining the second valve in active state if the first valve is disengaged, deactivating the second valve if the user input device is in the second position.
