A brake adjustment mechanism is provided for a bicycle wheel to allow cantilevered bicycle brakes to be adjusted quickly and easily and without the application of the brakes to the bicycle wheel. The brake adjustment mechanism employs a cable yoke which has a body adapted for connection to the flexible brake cable of a conventional cantilevered bicycle brake. The yoke has a pair of projecting supports that extend outwardly from opposite sides of a yoke body and toward opposite sides of the bicycle wheel. A separate socket is carried by each of the projecting supports. The sockets are movable in rotation relative to the yoke and each socket has a tapped opening facing a separate one of the bicycle brake lever arms. A pair of elongated rigid rods are each secured at one end to separate ones of the bicycle brake lever arms. Both of the elongated rods have externally threaded ends which are threadably engaged in separate ones of the tapped openings of the sockets. Rotation of the sockets relative to the threaded rods varies the overall effective length of the rigid structures formed by the sockets and the rods, thereby varying the initial dispositions of the brake lever arms and the initial positions of the brake pads to be adjusted in the absence of a braking force.
