From the BF GOODRICH guide: CARBON BRAKE LIFE IMPROVEMENT Recommendations:
1)Minimize number of taxi brake applications, especially prior to takeoff.
-Anticipate engine spool up and spool down characteristics to avoid overshooting desired taxi speed.
-Combine several short taxi applications into fewer, longer taxi applications.
2)Apply brakes sooner during landing stop.
-Utilize lower levels of thrust reverse.
-Utilize higher autobrake settings or manual braking.
When the BF Goodrich rep came and talked to our group, he said that the majority of the wear was done on the first flight of the day, when the brakes were cold. 300 degrees was about optimun for the least amount of wear.
