Are front calipers on the front of YJ side specific?

Just picked up my new calipers from Autozone and they are both the same caliper but just packaged in different numbered boxes (C252 and C253). This is the second time I have gone back and this time they were shipped unopened from their warehouse. Am I missing something here? Are the calipers side specific? If I use these new ones the bleeder and hose connection will be upside down on one side. Is it possible Jeep put the wrong caliper on one side or are they just a universal part for both sides like Autozone keeps giving me?

Yes they are side specific and the bleeders need to be at the top. It will not work if they aren't you can't get the air out when bleeding.

Ahhh. So the parts are packaged wrong. Packaged wrong twice I might add. When you say the bleeder needs to be on top do you mean slightly higher than the hose inlet? I noticed on the caliper that the casting has the bleeder valve cast just slightly higher that the hose inlet. Or do you mean the entire caliper should be installed with the hose connection and bleeder valve being toward the top of the caliper and not the bottom. I have both off the jeep so I really have no basis of comparison. My dumb mistake at being overly anxious.

X2. They should be a mirror image of each other. Also the shape of the contact points are different top and bottom. I can't recall which side the calipers rest on the straight edge (top or bottom) but I think it was the top. The caliper locks into place as you pivot it into its bolt up position. That edge is a critical part of its effectiveness to be able to stop the vehicle. This way, the caliper is not pushing against the mounting bolts whilst the brakes are applied. The mount takes most of the force. The bolts prevent the caliper from pivoting out.

1) or you are installing them on the wrong side....

2) it needs to be on the top so the air in the caliper is the first thing to escape when you are bleeding your brakes, brake fluid does not float on air...

I took the calipers back to Autozone. They gave me 2 drivers side calipers. The ones they gave me are not a mirror image of each other and are exactly the same. They did not have them in stock so rather than take another chance with the wrong parts I ordered from Advance Auto this time and they were actually a little cheaper.
