Hey guys, just jumped over here recently from the "other" site. I have a few questions about the calipers on the GMT360 platform. Are the calipers themselves the same on both the 4.2L SWB and EXT versions of these trucks? I seem to remember reading somewhere that the difference is only the rotors and caliper brackets, but not the calipers themselves. Is this correct? If the difference is only the brackets and rotors, do most people here replace the brackets when they swap out a sticky caliper or is it not necessary? Thanks in advance for any information.
