Default Disc brake conversion, Am I missing something?

So I scored myself an 8.25 with a locker already in it. After having to deal with drum brakes once, and breaking almost every piece, i decided never again and wanted to convert to disc. When i got the axle, it came with backing plates for discs already. Im unsure what they came off of, but i picked up some new calipers, rotors, pads and e-brake pads for the project. The parts were for a 95zj. Here's my conundrum.





....they don't line up at all. Am I missing something?
as a side not the backing plates don't slide right on the axle either. I figured after doing some research before hand i might need to grind the hole a little.

heres the plate if it helps


Ideas?

I'd change the backing plates since you have no idea what they came off.

The backing plate looks correct. Flip the caliper. I'll get you a pic.

Default Discs and Calipers

I did the conversion using the Liberty parts. Your calipers don't look right, at least from what mine were. The floating pin/bushings bolted directly to the backing plate bosses and the tabs on the brake pads rested on the ears of the backing plate. The backing plates look correct though.

Pretty sure it is a illusion. Put a set of pads in there. The caliper bolts go thru the calipers & thread into the backing plate.

At 1:45 he removes the caliper. 8:35 reinstalled it. Only thing to add is make sure you match the pads up. There are tabs that engage in the backing plate. One end has a tab missing. Make sure it goes in last.

David,

I see what your saying. OP are you trying to thread the gold bolt into the backing plate? That is what should mount the caliper to the backing plate, and another like it in the other slider. The holes that show in the picture that are closer together are used to locate the brake pad on that side.

Just glad that you got it figured out. Also, make sure to get the pads right. I come across ALOT in the jy that are put on wrong.

And Liberty Backing Plate Bolts on, ZJ Backing Plate you need to grind out just a bit to slide on.
