Brake Rotors

300 Below’s cryogenic treatment technology for aerospace brake rotors ensures longer life, enhanced maintenance intervals, and minimal downtime for an aircraft aviation asset.

Just like brakes on a car, aircraft brakes eventually wear out and must be replaced. Aviation brake rotors work in extremely demanding conditions, where Maximum Landing Weight (MLW) must be measured to ensure components can tolerate the high impact of tens of thousands of kilograms of mass landing on a runway to then be rapidly slowed down within a limited confined distance.

Due to landing on a hotter earth surface and then escalating elevation into lower temperature high earth atmospheres, aircraft brake rotors are subjected to far wider variations in temperatures in a shorter period of time than normal vehicle brake rotors. The additional weights and pressure felt upon landing create additional stress on the metal, causing more rapid wear to the braking system. In addition, debris and dust accumulate on aircraft brakes and wear them out. Over time, aircraft brakes become less effective, less stable, and less secure.

If brake rotors are not replaced on a regular maintenance schedule, worn out aircraft brakes can seriously damage all components of the braking system. In these cases, expensive and intensive repairs are inevitable. Worn out aircraft brakes may also cause dangerous situations for a flight crew, cargo and passengers, particularly during flight landing operations, where the aircraft could fail to stop in the provided distance on the runway.

300 Below’s cryogenic treatment process ensures stress relief and stability for metals used in aviation brake rotors while also enhancing the wear resistance and heat transmissivity properties of the material so that friction and temperature concerns found through repetitive stopping are minimized.

Important note for our aviation industry clients:

300 Below does not process components for U.S. commercial aviation (individual major carrier airlines in the United States of America) due to an excess of trial attorneys operating in the commercial aviation sector wanting to sue every supplier for any reason during mechanical failure related aircraft accidents, but we are willing to help with general aviation (privately owned and operated aircraft) parts and components.

We are able to work directly with companies such as GE, Safran, CFM, Rolls Royce, AirBus, and Boeing so long as our treated parts and components do not end up on the end user aircraft in U.S. commercial aviation. We will gladly process components used during the manufacturing process of U.S. based aircraft, but we are not willing to treat brake rotors and other metals that are directly attached to U.S. commercial aircraft carrying civilian passengers.
