This procedure is called bedding and it is encouraged you follow the steps below upon completion of the installation. Find a safe and open area where you will be able to accelerate and stop safely multiple times. Accelerate to 35mph (55km/h) and aggressively stop to 5mph (8km/h) in rapid successions without letting the brakes cool down and without stopping. Repeat this six times. Accelerate to 35mph (55km/h) and this time, moderately stop to 5mph (8km/h) in rapid successions without letting the brakes cool down and without stopping. Drive around for approximately 6-8 minutes at a moderate speed without excessively using the brakes or coming to a complete stop. Once this is complete, stop the vehicle and allow the brakes to cool down. This should take about 40 minutes or so. This concludes the bedding procedure and you can now use your brakes normally. However, certain restrictions apply. Note on UPS Extended Area Surcharge: This surcharge is levied by UPS. CT, DE, DC, IL, IN, KY, ME, MD, MA, MI, NH, NJ, NY, NC, OH, PA, RI, SC, TN, VT, VA, WV.
