How can I tell if my 02 Deville DHS has "Heavy Duty" brakes or if they are "standard" ?? I have the TPMS and auto load leveling. Want to order some new rotors and pads but need to know what I have first.

Check the RPO codes under the spare tire cover then go to the Tech Tips section. I think there is a "sticky" there that has all GM RPO codes.

I was under the impression that only Caddys ordered for transportation services had the heavy duty brakes. And that all of the dealer stock cars had standard fare brakes.

I was just going to say HD was not to likely unless it was a limo.
