Carbon Brakes
The use of Autobrake results in a constant deceleration rate during the landing roll which is achieved by modulating the brake pressure within a single application. A single application means reduced brake wear. It is also a means of brake temperature optimisation. To increase carbon brake life brakes should be operated either cold or hot but not at intermediate warm temperatures. Brake wear is highest at temperatures between 80 and 250 degrees centigrade (indicated).
P.S. If the brake fans are running then the limiting temperature of 300 degrees is equivalent to 150 degrees indicated (not 250!).
