If ones warped, The rest are probably as well. Replace all pads, rotors and brake fluid as well. use synthetic, I'm sure it's black and has never been changed. You can do this yourself, no need to pay someone $160 for it. <_< Paint your calipers while you're in there and clean up everything with a heavy duty cleaner. I've also found the aristo strut bar, ebay, helps a little with minor shaking while braking.
