1. A hydraulic braking arrangement for controlling rear brakes of an off-road vehicle, the hydraulic braking arrangement comprising:
a hydro-mechanical service brake system fluidly connecting the rear brakes to a first source of fluid in pressure in response to a mechanical input imparted by a driver of the off-road vehicle;
a remote controlled service brake system fluidly connecting the rear brakes to a second source of fluid in pressure in response to a first remote input; and
a remote controlled park brake system fluidly connecting the rear brakes to a third source of fluid in pressure in response to a second remote input;
wherein the third source is an accumulator and the remote controlled park brake system comprises a valve fluidly interposed between the accumulator and the rear brakes, the valve being configured to allow or deny passage of fluid from the accumulator to the rear brakes in response to the second remote input, wherein the valve is a three-way, two-position valve.
