    Can anyone tell me if a sticky brake caliper can cause a low reverberating howl from the rear of a 2002 2500 4WD Siverado just after stopping,releasing the brakes and then pulling forward or backwards. It does not seem to appear at higher speeds. I have also noticed it on uneven situations like pulling into an inclined driveway that puts the frame into a twisting situation. Applying the brakes seems to eliminate the low howl.
    Any ideas would be helpful.

    It could be the calipers, but it could also be many other things. Bearings come to mind for me after reading your description. Only way to know is to check it out. If it is the calipers, I would think there will be signs of it. Color changes on the rotor, warpage of the rotor, lack of material on one pad or the other, grooving in the rotor.

    Pop the wheel off and check the rotor and pads. If they're good, take the rotor itself off and have a look at the emergency brake shoe behind it. I've seen many of them inexplicably get stuck and grind right down to the metal.
