Park Tool Disc Brake Mount Facing Tool DT-1.2 (new, in box)

New in box, never used. Outside of box is dirty from years of shop drawer storage

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.
