Abstract
Example hydraulic brake apparatus and related methods are described herein. An example apparatus disclosed herein includes a parking brake valve having an inlet fluidly coupled to a pump and an outlet fluidly coupled to a brake. The parking brake valve is operable between an open state and a closed state to allow or block fluid through the parking brake valve. To lock the fluid in the brake in a parking brake mode, the parking brake valve is moved to the closed state by pumping fluid into the inlet.
