A rear brake unit for a cargo dolly includes a left and a right brake that each have a leaf spring with an eye end and a loop end. The eye end of the leaf spring is fixed but can rotate about its pin and the loop end of the leaf spring can slide in relation to a loop end pin when the brake shoe is in a braking position. The movement of the leaf spring allows the brake shoe to accommodate uneven tire wear between the pair of tires and apply effective braking force to each tire. The brakes are also connected to one another by a bar arranged to pivot about a center point of the brake unit, thereby allowing the brake unit to accommodate uneven tire wear between the left and right pair of rear tires.
