Bill, try the porterfield brake pads,and the frozen treated rotors they WILL fix the problem I have used the porterfield brakes on most all of my cars including my ex 911 turbo cause the factory rotors would CRACK I drive very HARD!!!!! and i installed a treated set from porterfield and no more cracks or pulsating pedal PROBLEM SOLVED one quick note do you change the brake fluid every year?also buy only ate or the factory rotors cause sometines the aftermarket rotors are well JUNK

good luck
