A wheel assembly 10 for a rail vehicle 600, wherein the wheel assembly 10 is centred on a rotational axis 12. The wheel assembly 10 comprises a shaft 14 which is non-rotatable about the rotational axis 12, and a wheel 16 configured for use on railway track which is carried on the shaft 14 and rotatable relative to the shaft 14 about the rotational axis 12. The wheel assembly further comprises a brake assembly 18 comprising a brake drum 20 coupled to the wheel 16 and defining a cylindrical inner bearing surface 22. There is also provided a first brake arm 140 comprising a first brake surface 142, the first brake arm 140 pivotably mounted such that: the first brake surface 142 is operable to engage with the drum bearing surface 22 in a first configuration of the brake assembly 18; and the first brake surface 142 is operable to be spaced apart from the drum bearing surface 22 in a second configuration of the brake assembly 18.
