A brake arrangement for a vehicle adapted for connection to an axle end. The brake arrangement includes a rotor disc adapted, in use, to rotate with the axle end and a stationary housing enclosing the rotor disc with one or more seals. A substantially sealed zone is provided within at least part of the stationary housing such that at least a braking effect region of the rotor disc, in use, passes through the substantially sealed zone. At least one friction pad is located adjacent a braking surface of the rotor disc in the braking effect region so as to operationally engage the braking surface during a vehicle braking operation. The stationary housing contains a liquid medium within at least the substantially sealed zone, the brake arrangement being characterized in that the liquid medium has a viscosity of less than 7 centistokes mm2/sec at 100° C.
