You certainly raised a valid line of enquiry. While I believe there are no issues within 2002 and 2003 swaps, at the moment there is no such tangible evidence for New Age/Old School swaps. We could test this in a number of ways though:
- are people who have done the swap wearing out and replacing rear brake pads at a typical pace?
- after pulling the ABS fuse, try several panic stops, past an outside observer. Look for abnormal front or rear lockup. Ideally compare between stock four wheel disc, stock drum/disc, upgraded 4 wheel disc. Might want to try this on gravel to avoid flat spotting, or use some tires you really hate
