Agree with Boxer on this.
On the 777 with carbon brakes we were told that the same amount of wear was inflicted on each application regardless of the pressure applied. (Not sure about duration of application, but I believe the inference was that this factor was irrelevant also)
Because of this 'fact' the training section encouraged the use of either left or right brake application only to effect retardation during taxi operations. This, they maintained, would reduce brake wear costs.
With conventional brakes none of the above is a factor.
