    About two months ago, I replaced my front rotors and pads, as well as rear pads. Ended up using pagid rotors and brembo pads for the front and I bedded them in after install. Recently I've started getting an ugly groaning/squealing noise at really low speeds, right before coming to a complete stop. Then, when I slowly release the brake pedal to roll forward, same noise right as the truck starts moving again. Do I need to re-bed the pads or is there something else going on? Car brakes fine otherwise, no vibrations. Any ideas?

    I'm curious about the bedding process you used, but separately, have you inspected the pads since that sound began? I recall a thread here where someone picked up a small stone or foreign object and it made a horrendous sound.

    The noise after releasing is not good. Check the pins to see they are clean and non binding. Also check the piston is not stuck. Reassemble and see if that eliminates it.

    Sounds like the calipers are sticking. Assuming that happens consistently. I'd use the brakes a bit and then stop the car and see if any one wheel seems hotter than the others.

    Thanks guys. My brakes do need a flush and bleed so calipers sticking might be it(or its sliding pins). As far as bedding, I warm them up, do 6-8 50-10mph sudden stops on a clear road and then drive around without stopping. I'll check it out.

    Did you cle3an and grease the pins when you replaced the pads?
