ABS Problem?

[doverarjim]

Help???  First problem with truck, got into truck today ABS light on dash came on and would not go off.  When I turned truck off I had a loud noise coming from under the truck right below the drivers seat, I looked at it and the brake lines ran to it and it was buzzing very loudly, the only way to get it to stip was to disconnect battery.  Its going to shop first thing in morning.  35596 miles on truck and this happens???
