Replace with 94+ rears and you'll be set and never have this problem again. I just spent a little over $500 to do front and rear rotors, calipers & pads on my lumina - and within the first couple hundred miles the pedal got its vibration back. I didn't have 15" wheels so I couldn't do the 94+ upgrade. I was planning on fixing hte car and selling it, but htat didn't happen so I'm stuck with the crappy brakes.
