code

Hi, I need to get new rear rotors for my 01 4wd Tahoe LS 5.3L . They have 1 piston caliper and 2 piston caliper types and that determines the rotor size. Can I tell anything from the glovebox sticker RPO codes? Or do I have to take the rear wheel off.............

Hey all, any idea on the “service park assistant†message on the dash, at startup, on a 2008 Chevy Tahoe LTZ?
