A bicycle brake mechanism is provided that protects a bicycle brake lever axle from bending. The bicycle brake mechanism of the invention employs a conventional brake mounting base, brake axle, and brake lever arm on a conventional bicycle frame. However, the invention employs a brake adapter of special construction which is interposed between each brake lever arm and the brake axle upon which it is mounted to isolate the brake axle from forces tending to bend the brake axle out of axial alignment. The adapter is rigidly connected to the brake mounting base and to a retaining structure which allows the brake lever arm mounted on the brake axle to rotate and apply the bicycle brakes in a conventional manner. The structure and location of the adapter isolate the brake axle or brake boss from forces that would otherwise bend the brake axle in a plane passing through the axis of rotation of the brake lever arm.
