A pushchair brake comprises a lever 12 pivotally mounted on a hub 20 on which a wheel, and sprocket(s) 15, are rotatably mounted, the lever having a locking bar 14 arranged to engage with the sprocket(s) so as to the lock the wheel. The lever is connected via a pair of cables to another lever on another wheel of the pushchair so that raising the first lever 12 causes the other lever on the other wheel to be raised, thus unlocking the wheels. Lowering the first lever 12 causes the other lever on the other wheel to be lowered, thus locking the wheels. <IMAGE>
