A braking system 10 includes: a supply line 12 which is adapted to be connected to a source of pressurised fluid; and a parking/service brake actuation assembly 23 including a brake actuator 23a, 23b, the parking/service brake actuator assembly 23 being operable such that the supply of pressurised fluid to the parking/service brake actuation assembly 23 causes the brake actuator 23a, 23b to move to a brake release position and the release of pressurised fluid from the parking/service brake actuation assembly 23 causes the brake actuator 23a, 23b to move to a brake apply position. The braking system further includes an emergency apply valve 20 which has a first inlet 20a which is connected to the supply line 12, a second inlet 20e which is connected to the service braking actuation assembly, an exhaust port which vents to a low pressure region, and an outlet 20a which is connected to the parking/service brake actuator assembly 23. The emergency apply valve 20 is movable between a first position in which the first inlet 20a is connected to the outlet 20b whilst the second inlet 20e is closed, a second position in which the outlet 20b is connected to the exhaust port whilst the first inlet 20a and second inlet 20e are closed, and a third position in which the second inlet 20e is connected to the outlet 20b whilst the first inlet 20a is closed.
