My 04 HERITAGE has recently been having the front brakes anti locks coming on when stopping sometimes on dry pavement. Not every time I stop but it seems to be doing it more lately. What do you guys think is the problem. By the way it a 4WD SC if it matters. Thanks

The ABS was kicking in just before coming to a stop on my 2002 4x4. I first changed the rear speed sensor, but the problem wasn't fixed. Then I changed both front wheel bearing / hub assemblies and problem solved. I did not know if the speed sensors were bad, or if something in the assembly was causing an incorrect reading. The bearing/hub assembly included new speed sensors so I changed the whole thing.

Pull the speed sensors and clean them. If the problem persists you have bad hub bearings.

I agree. Pull the front speed sensors and clean the hub surfaces. The sensor to exciter gap is excessive on one of them and causing the abs to not read correctly at lower speeds usually less than 10 mph. Chevy recalled their trucks for this, in salt belt states. Get this, MN isn't one of them.

Huh my truck used to do the same thing and now that I'm thinking about it after I changed the front wheel bearings it hasn't done it
