Although they look very cool I haven't noticed any difference in braking distance yet. The pads are definitely not ceramic and leave behind an incredible amount of dust. My old pads were almost gone and the rotors weren't far behind and I 100% believe they stopped the truck just as well. Let's see how long they last. UPDATE: 8 months and 15,000 miles and the rotors are BIG! Pads are still 70-80%. Although my calipers were sticking, no, they weren't. These brakes are junk. Absolute Chinese junk.
