the problem may be with the rotor surface. Try having them machined. Also be sure that all mating surfaces are clean and all metal parts are not touching.

your brakes squeak because of vibration. if you had pads replaced, not knowing the mileage, the rotors should have been "turned" on a brake lathe if they needed it. The noise is caused by metal to metal contact, with no lubrication, when brakes are applied. This is a common problem and you will hear all kinds of stories about how to fix it. The bottom line is that the shop that did your brakes was unprofessional or didn't know how to do the job. All movimg pats in the brake assembly need to be LIGHTLY lubed with high temp. grease. That will eliminate the squeeks. I do my own brakes and never had a squeek.

Remove the pads from the calipers, clean the metal contact points with a wire brush, apply some "rtv" silicone gasket maker to the metal contacts (not on the friction part of the pad, the metal part that sits on the caliper), and re-assemble. pressurize the brakes, but do not drive the car for about 30 minutes after pumping the brakes up. The squeal should be gone. One other thing that frequently helps is when you have the calipers off, take a cheap screwdriver and score the surfaces of the rotor, front and back, to "de-glaze" them. About 20-30 scratches per side.

New rotors maybe needed. When was the last time you had any maintanance on your rotors? Sometimes your pads will wear down your rotors unevenly. You may not have to replace them if you are still with in the refinishing limits for your rotors. They will need to mic. the rotors, this will measure the wear on the rotors and if it is still possible to refinish them.If they are to thin to refinish then you'll have to get the new rotors. Hope this helped.

If you had the pads changed by a mechanic, he should have checked the rotors, so most likely you won't need new ones. Disc brakes are prone to squeaking from many reasons: if they're wet, have dirt in them, etc. You can try to get some anti-squeak fluid to see if that would stop the squeaking.

I know they make a spray for that
