Non G related, for my daily driver truck, 2005 GMC Sierra Crew Cab JF3 brake option. Getting parts ready for a front brake job. Calipers and rotors are not original.
Looking at Rock Auto and all what they have to offer for calipers, AC Delco Gold Professional calipers, it doesn't say if the pistons are plastic, Phenolic, or steel. Did the originals come with Steel? I would rather rebuild them and save a lot of money but I'm not sure what is in there now or the condition of the bores and pistons, they are dragging now. When I take it down it has to be ready the same day.
