Seems like all the kits use old chevy or cadillac calipers. I looked under my employers '06 Dodge Cummins and that brake set-up looks promising. I'm sure the boss wouldn't let me pull his apart to take measurements. Has anyone looked into this or are the parts too expensive?

 

I have a 3rd gen AAM 11.5 that I gathered up a while ago, if it does end up in one of my 1st gen's I will have to go to a 17" wheel or bigger as a 16" wheel won't clear the calipers.

 

That 06 has the AAM axle. Most likely not much bolt on there.

Some of the later 2nd gens had 70 axles with disks on them. The problem there is the mounting flange for the drum and disks have different bolt patterns. Here is a pic of the drum backing plate deside a disk mounting plate.

 

I plan on getting new 17x9 wheels so clearance won't be an issue.
Gee, since it's just sitting around you may want to do some disassembly, you know, to clean it up and get it up to snuff for the swap. While yur at it, take some measurements and pictures to post for all our enlightenment!

 

Thanks for the picture Philip. Would an adapter be possible? The picture is showing the 2nd gen mounting plate? I ask because it looks like the 3rd gen I looked at yesterday.

 

I used the caliper and disk from a 1st gen 2wd truck on my conversion. I made my own mounting bracket and turned the hub down to fit the center of the 2wd disk. I don't have a parking brake currently but that is in the works in the from of a driveshaft brake. I could try and get some pics later if you need.

Here is a pretty good set up

andyt it would be interesting to see what you have done. 2nd or 3rd gen hardware would take care of the p. brake issue if it could be made to work. From what application are you sourcing the driveline brake?

longshot, the TSM kit is another chevy/cadillac set-up. The caddy calipers need to be removed to bleed because the bleed screw winds up on the low end of the caliper when attached to the mount.

 

Some 3rd gen guys I have read about ground on their calipers to fit 16s.

 

This is the kit I run, works well.

They also have the ability to do a parking brake on the NP 205 transfer case rear output, they used my truck as the prototype for a kit, you would probably have to call them since they don't list the specific kit for our trucks.

 

Although I have no experience with it, these guys make a plug-and-play kit as well:

That EGR kit has been around for years. The issue with that kit is it doesn't address the EMG brake cable hookup. It uses GM calipers. Those calipers need the Ebrake to function to keep the calipers adjusted properly.

Those GM calipers have issues if you live in the rust belt.

A friend used a EGR kit about 10 years ago. It was on his truck for 2 years. He went back to the orginal drums.

 

I have a set of brackets and new Eldorado calipers with ebrake waiting to go on (for like three years now) but just haven't made the time or spent the money for the brake lines and such. I like the idea of not having to pull my axles to do my rear brakes, but I don't want to end up with something inferior.

 

I installed the egr kit, with E-brake a year and a half ago and I could not be happier...Mark

 

I just need to man up and git-er dun.
