APS Brake Linings

Metallic and Semi-Metallic Brake Linings
Two types of brake linings are available: semi-metallic/organic (abrasive) and metallic (adherent). The part number of the brake assembly as determined by the OEM dictates which type of lining is to be used.

The semi-metallic linings are made with Kevlar fibers integrated into the material, providing the greatest stopping power and long lining life. The optimal operating temperature of the semi-metallic linings is 600-900 deg F.

The main ingredient in the metallic linings is iron. In an adherent system, a thin layer of lining material transfers and adheres to the disc during break-in. The optimal operating temperature range of the metallic linings is 950-1200 deg F.

Brake discs, rivets and pins also sold separately. APS linings can be used with any OEM or PMA discs.

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.

Break-In Procedures:

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.
