It was time for new brakes on my 2004 Pontiac Grand Prix GTP after 50,000 miles (not bad for factory issue pads). Here the mistake part: I paid a mechanic to cut all the rotors and install new pads. He used Thermo Quiet pads. DISASTER! I actually went off the road on a panic stop. It was worse than when I took the car in. BAD, VERY BAD. This car had excellent brakes from new, so this was puzzling. I took the rotors off and found some grease on the back rotors. Worse yet, the front rotors weren't cut right and there was a raised portion that I had to hand file down to achieve full contact area. Here's the good part. I put on these pads, which bedded in about 5 stops (as they instruct you to do). Now my car is a weapon once again and can stop by mental telepathy. Much, much better than stock, with no fade on hard driving. YIKES!!! Too soon to tell about dusting, but that's why you wash a car. Too soon to tell if they'll chew the rotors, but the stopping power is well worth both potential drawbacks. End of story.
