The offside rear caliper on my Chevy Blazer has seized so I need a replacement. Best price so far is £120 plus vat. I have a spare caliper but it is for the near side. I thought....why not use it on the offside? The only difference is the location of the bleed screw. If I bleed the system with the caliper not mounted so I can hold it up the right way (nipple on top) and block the pads so the piston doesn't come out, it should work, shouldn't it?
