Brake Lining conditioning
New Brake Lining is required to be Conditioned before release the aircraft for flying. Brake lining conditioning procedure as per Cessna 172R MM A. Non-asbestos organic lining: (1) Taxi airplane for 1500 feet (457.2 m) with engine at 1700 RPM, applying brake pedal force as needed to develop a 5 to 9 knots (9.3 to 16.7 km/hr) taxi speed. (2) Allow brakes to cool for 10 to 15 minutes. (3) Apply brakes and check to see if a high throttle static run up may be held with normal pedal force. If so, burn-in is completed. (4) If static run up cannot be held, allow brakes to completely cool then repeat steps 1 through 3 as needed to successfully hold. B. Iron-based metallic lining: (1) Perform two consecutive full stop braking applications from 30 to 35 knots (55.6 to 64.8 km/hr). Do not allow the brake discs to cool substantially between stops. NOTE: Light brake usage can cause the glaze to wear off, resulting in reduced brake performance. In such cases, the lining may be ...
