13" disc brakes for AMC's

I'm going to wait on the rebuild of my 77 AMX until I have my new bigger garage. I don't want to fill up my current garage with the AMX all apart before I finish the detail work on my Javelin. Having only 1 workable garage stall sucks. Having a 17" option for the front wheels does make the 13" brake option very viable. I just hope Rousch doesn't run out of them before I buy another set.

There is no drop on my setup since I already have an AirRide front suspension. The truck Hemi oil pan is pretty low and any more drop than I already have will be too low. There is no reason that if you use a thicker plate that you can't just make an all in one drop/ caliper mount. My bracket simply replaces the factory caliper mounting bracket but with a drum spindle. I am considering using my removed disc spindles on my next conversion since they have bigger bearings. Bigger bearings means a stronger set up with a slightly larger spindle.

The very first pic on this thread shows how I removed a small amount of material around the hub center to let the Ford disc fit over it. Ford have a slightly smaller centric than AMC but only by a very small amount. I removed the studs to clear the grinding wheel that was chucked into a bench top drill press. I bolted a spindle to the plate on the press but left the plate slightly loose so I could feed the hub into the sanding stone gradually so it would remain perfectly round. You really need a drill press to keep everything square and round. A machine shop could do this for you but it is such a small difference in diameter that it only took a few minutes to reduce the diameter the needed amount. I had consider using a hole saw with the correct inner diameter to cut some metal off but this method worked pretty fast and accurate and I already had the drill press. The grinding stone is just a cheap one but worked great. Now a replacement Ford disc will fit with no extra work. I did a short video but can't seem to find it in my Photobucket albums. If you still need it I can repost it since I saved it on my phone I think.
I have added over 15,000 miles on this car since the conversion with no braking issues at all other than breaking the pad off my modified brake pedal during a pretty hard panic stop. The car still stopped great. All the bolts and spacers have held up with no issues. I still hit over 100 mph on a pretty regular basis but the Hemi limits me to 108 with some sort of factory rev limiter.
There are more pics of the brake swap in my hemi Javelin folder on Photobucket. Just do a search there.

sweet thank you

well i got the plates made and installed. ( had the fab shop make a set for 13in brakes at the same time so down the line i can upgrade). but my delema was when the caliper is inslalled the rotor rubs the back of it even before the pads are on. was wondering if you had any issue like this or what i may have gone wrong. i only have a few pics at my disposl but none that show the rubbing.  https://www.flickr.com/photos/19975275@N05/14516782946/ - https://www.flickr.com/photos/19975275@N05/14516782946/
