    wierd grind noise when braking

    like the title says this noise started a few days ago on my truck. coming from the front, noticed that the left front brake was low, so i replaced it. this is also where the noise is coming from.

    brake pad was un even and lower than the other side on the front. the calipers airnt sticking that bad. but when i spun the wheel while jacked up it did make a light grind sound.

    ever since i replaced the pads its worse, i was also making a u turn and it made this sound with out touching the brake.

    i do have dual calipers so maybe one is out. or maybe a bad wheel bearing. ??

    could be a stuck caliber or bad bearing.


    with the truck on jack stand, have someone press the breaks while you look at them. You should be able to see the caliber clamp together equally.

    If looks ok with the break off, spin the rotor listen for grinding noise, see if the pads are rubbing.

    You can pull and shake the wheel hub side to side, any movement = bad hub.
