A brake for bicycles includes a pair of levers each having a holding arm for a brake shoe. The first lever is articulated about a first pivot pin secured to the bicycle frame. A linking element is secured to the pivot pin and carries a second pivot pin parallel to the first pivot pin for articulating the second lever. A spring tends to hold the arms of the two levers apart and a device is provided for adjusting the spacing of the arms of the levers. This adjustment device includes a rocking member articulated about the second pivot pin and engaging one of the pair of levers and an adjustable threaded member on the other of the pair of levers.
