A wheel brake mechanism for a pushchair which is foldable about axes X, Y, comprises primary brake means 8, 9 engageable with a first wheel 6; at least one subsidiary brake means 8, 9 engageable with a respective at least one other wheel 6; and coupling means 20, 50a, 50b which operatively couple the primary brake means to the or each subsidiary brake means. The coupling means are constructed and arranged such that the operative coupling is permanent and unaffected by the folded state of the chair. In one embodiment, two Bowden cables 50a, 50b, are interconnected by a rack and pinion device 20; whilst in another embodiment, the primary brake means is connected to a subsidiary brake means by two Bowden cables (61, 62, Fig. 5). The use of Bowden cables permits folding of the chair without affecting the braking operation of the mechanism. <IMAGE>
