After more than 20 years repairing and overhauling brakes for the aviation industry, Hope Aero has extensive experience and hands-on expertise servicing virtually every brake type from every manufacturer, both mineral oil- and Skydrol-based systems.
After being disassembled and cleaned, brake rotors are weighed and measured for minimum weight and thickness. Discs that have become warped from excessive heat are straightened as required to ensure smooth, consistent braking. Rotors are ground to remove high spots. The brake housing, torque tube, pressure plate and stationary discs are media blasted before being extensively inspected by our expert NDT inspection team. Brake housings are painted with epoxy paint and oven-baked to ensure a durable protective finish.
In sub-assembly, the pressure plate, torque tube and stationary discs are re-padded, and the heat stack is checked against minimum height specs. For final assembly, the refinished housing and heat stack are reassembled and torqued to specification, and the adjusters are set, torqued and locked. All brakes are pressure checked for operation and leakage. As with everything we do at Hope Aero, we consider minimum tolerances to be merely a starting point, and we constantly strive to meet tighter specs than the minimums allowed. Finer tolerances translate directly into better performance and a better passenger experience, as well as longer TBO times.
