AMC 20 Disc brake conversion

I'm at the end of a very long axle re-build so I'm a bit frustrated. New ring and pinion, new one piece axles, TRUSSED (thanx BESRK) all new seals and bearings, so I'm down to the disc brakes. (BTW, I got the calliper mounting brackets from BESRK too, talented man.....shameless plug for my man BESRK! )

I bought the 96 maxima calipers, the 97 geo tracker 2 door front rotors. All the write ups i've read say this set up will work. Well, they look pretty but the caliper is too thick, or so it seems.

I've compressed the piston all the way and still....missed it by THAT much. SO, is my only option to have the rotors turned down a 1/4 in or so? can I even do that? I mean will a shop shave that much off? Shall I just shave down the pads a bit? or is that just stupid talking? MAN I WANTED THIS THING RUNNIONG THIS WEEKEND.

Are the 96 and 97 tracker rotors the same? IIRC it was 96 rotors, and rear calipers from 95-2001.

Can't really tell what you have from the pics.
I did this too. Didn't have any trouble getting them to fit over the rotors. The rotors are only 8mm/.315 thick.
The only thing I had to do was use washers(pic 2 & 5) to center the caliper over the rotor.
These have since been changed out with spacers of equal thicknesses.
Posting some pics.
Don't think they will help you. But, ya never know.
300 ZX calipers/Samauri rotors.

Good luck

Did you buy the caliper bracket or just the caliper. Something does not look right. You need the caliper, caliper and the mount to attach to thr axle. It looks like you have the caliper attached directly to the axle bracket.

I have the 97 nissan maxima calipers, the caliper bracket and the fabbed bracket on the axle housing. I havent attached the caliper to the bracket yet, i was just dry fitting it. It seems like the pads are too thick, they wont press in any more than they are.

And that is one beautiful set up you have, kudos. Yea, i have spacers but i'm not even that far yet. I'm not worried about the spacing between the bracket and the rotor yet, the pads just wont fit around the caliper. Thanks for the replies.

IDK if you can tell from this pic. but i'm not connected to the axle housing caliper bracket. I'm just dry fitting to see if the pads fit around the rotor.

I used a mallet and gave it a few wraps and it fit on TIGHTLY, but I know that's gona cause issues. Just shave the rotor? can I ? It seems like the piston should be more compressed, but both stick out the same distance and don't compress any more, even with a c clamp

IIRC, you have to screw the pistons back into the calipers. A C-clamp won't do it.
Need a tool like this.

That worked on a '96 Maxima, at least....

I've never heard of SCREWING them in. The link says page can not be found. But there is a TOOL to SCREW in the piston? Man, I've done maybe 50 brake jobs and have always been able to losen the bleed nipple and compress the piston with a c-clamp. So I'll google the tool. Don't want anyone saying "have you googled it?" jk, thanks guys.

I was thinking I bought the wrong rotors, turns out, I"M JUST AN IDIOT. FITS PERFECTLY NOW. (i snuck out to the garage while my wife was in bed ITS 11 PM, I could get my balls cut off for that!) Thanks again. I will sleep soundly tonight...... oh, yall know what i'm saying, trying to sleep, "Whats wrong with the jeeP"
