why did you even ask if the squealing stop if I touch the brake pedal?, If you read my response, of course the noise didn't stop. I said in the post that it squeals when I brake, and so therefore it doesn't stop if I touch the brake, it only squeals when I brake.
Disk brakes usually have a small amount of contact between the pads & rotors even when there's no pressure on the brake pedal, this light contact can cause a squeal (or squeak if the rotor isn't perfectly symmetrical in alignment and thickness). When you press the pedal momentarily, that pressure change on the pad/rotor assembly can be enough to momentarily stop the squeal or squeak. That's the reason for that type of question.

Another condition can cause the squeak/ squeal when you step on the brake pedal - I'm assuming this is what you have.

Not knowing what your mechanic saw and how he "repaired" the brakes on your car makes it hard to give you a definitive diagnosis on what your current problem is, but here are some things I'd look for:

  • Physical condition of the rotor - is it grooved, straight, etc.?
  • Was the glaze removed? The old pads would have left a layer of glaze on your rotors that could cause this noise if the glaze wasn't removed.
  • What brand & quality of parts were used? Some pads are notorious for causing a squeal even though there's nothing physically wrong with the installation or any components.
  • Were all the moving parts of the caliper properly lubricated. Some calipers (like Hyundai's) are notorious for seizing partially causing asymmetrical brake clamping - this can cause a squeal because there is no clamping but only a push by the "piston pad" on one side of the rotor.
