APS BlackSteel Brake Discs and Linings

Improve braking performance!

BlackSteel Brake Discs
The high quality APS BlackSteel brake discs are one piece forgings, eliminating weld failures. BlackSteel forged discs are machined and then put through a proprietary heat treating process that strengthens the steel by bonding the carbon, oxygen, and nitrogen in the top layer of the metal. The process is not a coating, but a transformation of the top layer of the metal, providing corrosion resistance. The reduction of corrosion, pitting, rusting and longer service life result in enhanced safety, durability and value, while providing optimum braking performance and strength.

Metallic and Semi-Metallic Brake Linings
The metallic (adherent) and semi-metallic/organic (abrasive) brake linings utilize the latest in friction material technology, using Kevlar fibers for bonding, which increases service life and durability without changing the coefficient of friction required for proper braking performance.

Rivets and Pins
Lining retaining pins are used on various metallic brake linings and rivets are used on various organic brake linings.

Please note:
Eligibility depends on the wheel, brake, and aircraft make, model, and serial number. Please see the current catalog information or click "View Eligible Aircraft" and read any applicable comments to verify and/or determine eligibility.

Warning:
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 break-in procedures upon installation.
