I often read about replacing calipers in pairs. I have a sheared off bleeder on a caliper and one of the bolts for the ball joint mount is sheared off, so i got a donor srutspindlecaliper and will rebuild with new inner outer tie rods ball joints struts etc.. My question is will the two used calipers, my original, and the new donor cause any problems they both have about the same wear and tear. I should have pulled both sides but i didn't have the cash with me to get both. Went back today to get the pass. side and the crusher got to it first.Should i try to remove the busted bleeder off my original. Thanks.
