The break-in procedure is critical to brake performance. Perform 5 moderate to aggressive stops from 40mph down to 10mph in rapid succession without letting the brakes cool and do not come to a complete stop. Then perform 5 mod­erate stops from 35mph to 5mph in rapid succession without letting the brakes cool. The reason for a proper break-in is to establish an even layer of friction material deposited on the rotors from the brake pads. It is very important that this initial layer of friction ma
