Abstract
A ball bearing brake has a spindle with a central axis. Each member of a pair of caliper members has a lever and a brake pad arm. The members are fitted on the spindle for rotation around the axis, and for limited axial movement during assembly and adjustment. Each brake pad arm carries a brake pad to be pressed against a bicycle wheel. An end member mountable to the bicycle structure includes means to engage the spindle and to compress a stack between itself and a head on the spindle. Four sets of bearing balls are formed around the spindle, respectively confined (1) by a race adjustment to the head of the spindle and one of the lever arms (2) by a race on the first lever arm and on an intermediate race member (3) by another race on the intermediate race member and on the other lever arm, and (4) between a race on the said other lever arm and a race adjacent to the end member.
