Well noted on the small to zero cost difference between the junkyard pieces + rebuild cost and re-manufactured ones. I can't seem to find a new or Re-manufactured set of 82-83 200sx or 86-87 Maxima calipers. It seems there are plenty of Right rear re-maned calipers, but no Lefts to be found, they are out of stock everywhere I look. you can however find both rears for the model year 1988.
I didn't want to be out the full re-manufactured price on a "might work" situation, so did end up going to the junkyard and picked them up 😁. Total for both with brackets and hardware was $88. The plan is of course to rebuild if they end up working with some other Rotor. Should i measure the distance on the bracket from the hub mounting point to the caliper mounting point to compare to the 86-87 measurement? I would think this would give the rotor size difference, no?
I figured it was a small price to pay even if they didn't end up working we'd learn something new. If they do end up working with a different rotor, then we all have a new option. it will be a while before i can get an answer as i don't have any of the custom mounting brackets. when I do I'll update here. Thanks all for helping a 510 newb.
