i'm regular, 85 mile route, 630 boxes and put on brakes/rotors twice a year.You say you just put brakes on 2x per year? Are you regular? If so you must have a VERY short route, as I put brakes and rotors on every 3 and or at most 4 months.
most of my roads are dirt/gravel and i don't go faster than 15 - 20 miles an hour on them. approaching a box, i ease off the gas and let the vehicle slow down "naturally".
that was a parting tip to me as an rca from an old reg...because i used to go thru brakes like water.
