The rear calipers on a wagon have a slightly larger bore but use the same pads. This gives the heavier rear end of the wagon a little more braking power. I would not mix with a sedan caliper. I would not hesitate to use different brands caliper on either side though. The bores of the different brands are the same as are the pads.

The fsm is written for a dealer so makes recommendations in order for a business to make money and avoid any potential problem. A hobbiest 40 years later has different needs.
