So I'm changing calipers and rotors on my truck and find that the backing plates are rotted. None of the local stores have the parts (NAPA and CarQuest). So I go to the dealer (I hate going to the dealer, they rip you off). So the parts guy tells me that they are part of an assembly that comes with the caliper bracket, 4 studs, and all of the parking brake parts for $335 each side. Of course the assembly doesn't include the rubber boot where the cable attaches. Is this true? Can anyone direct me to a place to just get the backing plates? Any other suggestions?
