Is it the pedal pulsating, or is it the body vibrating?
I did brakes on my GTP 25,000 mile ago and still smooth.
I bought the better pads and rotors from Rockauto.com.
They cost a little bit more but are still smooth.
I also agree with aboove, driving style does have a part
to play when it comes to brake wear and tear. Now I am
not totally easy on my brake either, I like to lay into them hard
once and a while to see how they are grabbing if I need the
extra stopping power.
