A wheel and drum brake assembly comprises a wheel with an internal axially-extending cylindrical braking member 11 spaced from the inner periphery of the rim 1 and associated with an annular radially-extending web 10 forming part of the wheel, a non-rotatable torque plate 13 with which are associated non- rotatable brake-applying members 19, and a truncated conical structure 7 integral with the web 10 and forming with the inner periphery of the rim 1 a venturi chamber through which air is directed over the braking surfaces. The brake-applying pistons 19 are mounted in cylinders formed in blocks 16 carried by the torque plate 13 and extending only over a limited arc of contact, the supply of pressurefluid to the cylinders causing friction pads 20, 21 to be forced against the drum surfaces which comprise thin endless metal bands 25, 26, 27, 28 engaging asbestos drum linings as described in Specification 650,499. Those portions of the bands not engaged by the pads 20, 21 move out of contact with the asbestos, thus enabling the cooling air to pass over both sides of the bands. Alternatively the braking surfaces may be of the form described in Specification 674,944. In further constructions two concentric drums such as 11 may be carried by the web, or the brake elements may be mounted on each side of the torque plate, Figs. 3, 4 and 5 (not shown). In the case of the construction embodying two concentric drums, two braking stations may be provided diametrically opposite one another, one set of friction pads engaging the inner drum and the other set the outer drum. The friction pads may be mounted for rocking movement relatively to the operating pistons as described in Specification 665,273, and scoops or deflectors may be provided to divert cooling air through the wheel as in Specification 654,496 or 654,499.
