767-300's have carbon brakes. They are very good brakes, but good for only 1 stop. Using auto brakes will actually elevate your brake temps over later manual braking, regardless of what TK says. Brake wear is different than brake temps.

If you want less brake wear, use auto brakes, but you will have higher temps, because it brakes earlier in the landing roll=more energy dissapated through braking.

If you want lower temps, don't use auto brakes, use more reverse, and longer roll with later light manual braking. Fewer number of applications and lighter manual braking will dramatically lower temps.

Hard to do both. If you do it the TK way and maximize the use of autobrakes, you will have higher temps.
