I can just imagine the pax reaction if they were told the truth... "Good Morning L&G, on this B767 we have 8 brake assemblies, this morning two of them are not working, we are still going to fly you to FRA on time, however, just after takeoff we are going to leave the wheels down for two minutes to allow them to spin to a stop! Dont worry about it!!!!!!!"
This MEL procedure is permitted on the B747/757/767/777 and is probably a lot more common than people realize.
