Darius, in case you are still following this thread:
with a light a/c like a C560, a few kts over Vref won't make the brakes only last half their lifetime, unless you always land with max. tailwind component.
Your POH or AOM will give you an idea about the preferred landing technique for your aircraft.
Depending on the type of brakes, your guys might be using the brakes not enough. On the ERJ145 (carbon brakes) the preferred procedure is to apply very positive braking after touchdown, in order to get heat into the brakes. The brake wear is largely due to the number of brake applications. According to Embraer, ERJs equipped with thrust reverse wear down the brakes faster than those without. This is due to the crews not getting enough heat into the brakes. We have some Captains on our fleet, that have previously flown B735 or A340 (as F/O) and have tried to teach our F/Os the wrong braking technique. Now we have to hammer the Embraer way into their heads again.
