Disc Brake Mount Facing Tool

The DT-1.2 has been discontinued and replaced by the DT-5.

In order to ensure disc brakes function smoothly and accurately, the frame’s mounting tabs must be parallel with the brake pads and rotor. The DT-1.2 is designed to perfectly machine the face of each tab, removing paint and material to create a flat surface.
