Am I the only one who thinks this is way more trouble than it's worth?
I know that the first-gen rear calipers have a bad reputation, but it's not deserved in my (admittedly limited) experience. I know that on my '92 and '93 Luminas, the rear calipers haven't given me excessive trouble--at least, not more than any other calipers, and less than typical aluminum-bodied calipers. I have had them apart for cleaning and inspection; and even replaced them with "rebuilt" calipers in desperation, trying to fix a "hard pedal, poor braking power" situation a long time ago.
The poor braking was due to failing vacuum power boosters on both vehicles, not the calipers/rotors/pads in front or in back.
