My brakes pulse lightly when stopping. It happened after a high speed stop to stop at a red light when coming off the highway. I should have let the car lightly roll ahead after stopping to let the rotor cool and not bake under the pad, but oh well. If you are looking for a good upgrade, purchasing C6 Z51 brake rotors, new pads and C6 Z51 caliper brackets is a really good (And cheap!!! except for the caliper brackets) brake upgrade for our cars.
However, if you want to just replace rotors and pads, check out Corvette Central or Rock Auto.
