My 2003 regular cab long be 4X4 base model 4.8 Silverado has a sticky rear caliper piston at 45K miles. The system has thinner rotors and single piston calipers that comes on non limited slip axles. Thinking about replacing system with the two piston calipers and thicker rotors that come on limited slip axles. It seems it is a bolt on swap requiring new caliper brackets, calipers, pads and rotors. Not sure if the hoses need to be replaced. Due to stuck caliper and parts needed to repair system, it'd be a good time to do it if it is indeed a worthwhile upgrade. I've heard suggestions researching that maybe the master cylinder and proportioning valve are different and may not function properly with these parts from the old system. It may be that ABS takes care of this and the original parts work just fine. Know if this swap is a simple, straightforward, and worthwhile as it seems?
