The old rotor was heavily scored as were the pads after about ten hours with the new metallic brake pads and maybe 60 landing and taxi cycles (see 1-Old Rotor & 2-Wear on Old Rotor). I decided to consult with my good friend and International racing driver Amos Johnson. One look at the old rotor and his comment was that the pads were too aggressive for the rotor! Amos decided to bring two close associates into the discussion, one an expert on brakes and especially pad material and his former machinist that worked for his company building & racing cars for GM, AMC, & Mazda. Our discussions settled on two approaches, first slotting the rotors to vent the pads and second the possibility of changing to some formulation of Carbon-Metallic brake pads. I decided to go one step at a time to test the improvements. Since the original rotors we in poor condition I decided to order a new set of rotors.
