1. A vehicle axle beam and brake assembly comprising an internal shoe drum brake having brake shoes operated by a brake camshaft (22) supported for rotation by two spaced, first and second, bearing assemblies (16, 21) carried by an axle beam (1), the first bearing assembly (16) being supported on the axle beam by a brake anchor bracket (8;

  • 37), having opposite first and second sides, and the brake camshaft having adjacent and remote ends respectively near to and remote from the brake anchor bracket and a cam (23) at said adjacent end by means of which the brake shoes are caused to be actuated upon rotation of the brake camshaft, the first bearing assembly (16) being releasably mounted on a first mounting at the brake anchor bracket having an aperture (13;

    38) of a shape to allow the cam (23) to be passed therethrough and through which the brake camshaft (22) extends so that the cam is adjacent said first side of the brake anchor bracket and the brake camshaft extends from said second side to the second bearing assembly, the second bearing assembly (21) being releasably secured to the axle beam (1) at a second mounting (9) also having an aperture (10) through which the brake camshaft extends, and the aperture (10;

    38) of at least one of the mountings being open or openable laterally of the brake camshaft to enable the brake camshaft, the construction and arrangement being such that when the bearing assemblies have been released from the mountings the apertures enable the brake camshaft, with both of the bearing assemblies thereon, to be manoeuvred to pass the cam from said first side to said second side of the brake anchor bracket and withdraw the brake camshaft and the bearing assemblies from the mountings.
