A brake for the wheels on one axle (24) of a pushchair or perambulator comprises a series of radially oriented ribs on one side face of each of the wheels and a respective brake member (42, 44) mounted for reciprocating movement parallel to the axle into and out of engagement with the ribs on a corresponding wheel. Each of the brake members (42, 44) has a cam follower (38, 40) on its inboard end engaging with a cam member (30) which is mounted for angular movement about a horizontal axis perpendicular to the axle (24). A foot-operated lever (32) is coupled to the cam member (30) so that downward pressure on one end causes angular movement of the cam member (30) in a first direction and downward pressure on the other end causes angular movement of the cam member (30) in a second direction. <IMAGE>
