Should I disable my ABS when bedding in my new pads

99accent

just replaced the ceramic pads on my 2003 pathfinder 4 wheel DR captive rotors, the rotors had some rough surface yet within specs of thickness however they stopped well and even until I replaced the pads, now the truck has steering wheel shudder , I did bid them in right , I cleaned the rotors real good after I notice about 2 black spots on the rotor after about driving 400 miles around at slow speeds say 50 mph , so I sanded then clean and resprayed with the brake cleaner and it did get a little better. , still the shudder which stops shuddering at a 6 mph . my question, if I disable my ABS will the pads Bid in better and faster? then I can reconnect the fuse for the ABS when all is well or is this just a useless thought.

I don't think so. In general, heavy braking is to be avoided during pad break-in. I think your problem is the old rotors. Sounds like you are getting a "grip-slip,grip-slip" effect because of irregular surfaces on the old rotors, which prevent the new pads from laying down an even transfer film.

I think you're going to have to pull the rotors and turn them or replace them. Before you do that, check the rotors for run-out. Excessive run out might also cause these vibration issues.
