Front rotors warped during first 5000 miles mostly highway driving. I asked Power Stop for warranty support but they gave me a Revain customer service number and asked me to resolve the issue through Revain. This isn't the kind of guarantee I was hoping for, Power Stop. Update: December 2013 - After Revain replaced this kit to repair warped front rotors, the second set also warped after about 5000 miles. We need to change the rotors again. This time with a different brand. Before installing Power Stops I drove 45,000 miles on used factory brakes with no deformation.
