Abs

When I come to a normal stop my ABS starts working. I am not hitting the pedal hard. Can anyone give some advice on whats wrong?

There's a couple of posts in the Sierra forum about ABS problems with a 2000 Sierra, maybe the same problem?

Mine does the same thing and it is getting worse

Most likely one or both of your wheel bearings is worn.

Have it checked out.

Hope this helps.
