Now go to what the manufacurer says about reverse thrust usage...read all.
I have 'read all' thanks very much. The FCTM states the following:

Full reverse thrust should be used when stopping distance is limited or when runway conditions significantly affect braking action. Idle reverse thrust may be used when conditions permit.
The FCTM makes lots of other statements regarding brake temperature, brake life, etc, some of which are contradictory. However, nowhere does it recommend the technique you described.

Greetings,

The Airbus FCTM, adresses the brakes wear, efficiency, and temperature stating that max brake temp before takeoff must be max 300 deg C (explaining that it is a protection against igniting hydraulic fluid that might leak) then explains that brake wear is minimum and efficiency is best when brakes are hot 9above 150 deg C), but further Airbus specifies that if the brakes are 300 deg C, then a reject takeoff may not be successfull if high energy is required
Furthermore loss of braking is a memory item meaning he brakes are not that flawless
BTW I know that the subject was B777
