Hello, new user looking for help with 03 2500HD - 56,000 miles. I've been having some strange problems with the anti-lock brakes. At least I think it's the anti-locks brakes. Under slow, light stops I can feel that anti lock vibration during the last second just before the vehicle stops. It's always during the last foot of a stop and only at slow speeds, under 5 MPH. It's never been a problem during harder, faster stops. Any ideas? Thanks for any help or advice.
