APS BlackSteel Brake Discs   
Improve braking performance


      Unmachined forging


APS BlackSteel brake discs are state-of-the-art CNC machined from a one-piece forging.
When the metal is forged, it creates a directional grain flow that follows the contour of the disc. This allows for a much stronger disc that has a reduced risk of the cracking and catastrophic failures associated with inferior welded designs.


The APS proprietary heat treatment has a two-fold purpose. The heat treatment strengthens the steel by bonding the carbon, oxygen and nitrogen in the top layer of the metal. This is not a coating that can wear off, as the steel itself is transformed. The heat treatment gives the steel its black appearance and provides the surface with a high resistance to the corrosion and oxidation associated with the extreme thermal cycling experienced in aircraft braking systems. This makes it an excellent choice for agricultural aircraft that work in a harsh, chemical environment, as well as for anyone who leaves their aircraft outside most of the time.


Brake liningsrivets and pins also sold separately. Any OEM or PMA linings can be used with APS discs.


One of the most important factors in disc and lining performance and safety margins is proper break-in. In order for any brake system to work optimally, the disc and linings must be properly bedded. Please follow the Lining Break-In Procedures upon installation.


Brake bleed valveswheel bearing cups and cones, and wheel grease seals also available.
