Using reverse IDLE down to normal taxy speed has a significant effect on the amount of braking required and therefore on both brake life and temperatures
BOAC. Point well taken. I misinterpreted your meaning when you mentioned redeployment of the thrust reversers. I thought you meant that by redeployng you were intending to apply full reverse again. Of course you are correct for the reasons offered when advising use of idle reverse until at taxi speed.
