15. Take a look at the other side of the bike where the stock H-D rotor would have been; nice and clean. Once we started to test out the Brakester, we had to be careful on the first ride. The rotor needed time to break in, then after about 10 miles of on and off the pedal to get the pads good and hot we started to notice the biting power. It didn't take long to get the rear wheel to lock up (not that we want it, but it was there).
