A modulator (30) comprising an inlet (31), an exhaust (33) and an outlet (32), the modulator (30) comprising a piston (34) moveable in response to a control pressure in a control chamber (35) to vary to supply of fluid under pressure to the outlet (32), wherein the modulator (30) comprises a first end face (30a) and a second end face (30b) wherein the exhaust (33) and the inlet (31) are provided in the first end face (30a) and the outlet (32) is provided in the second end face (30b). The modulator (30) further comprising a hold solenoid (46) connected between the inlet (31) and the control chamber (35), and a dump solenoid (48) connected between the control chamber (35) and the exhaust (33), wherein the connections between the hold solenoid (46), the exhaust (33) and the control chamber (35) and the connections between the dump solenoid (48), the control chamber (35) and the inlet (31) do not cross the plane of the piston (34). <IMAGE> |
