Does anyone have ANY info about how they did this? Right now my plans are to use a modofied version of the Dynatrac caliper bracket, Dana 44 calipers, and I *guess* a 3/4 ton chevy rotor...

I have plans to use 16.5" wheels - any clue ohw much backspacing I can get away with on a setup like this? I want as much bs as possible to keep it narrow and get better turning out of the front end.

If you are running 16.5 wheels, then you don't need to change anything...just use the stock brakes.

I've seen 5" bs 16.5's on Chevy 1 ton brakes and they have tons of clearance

Yeah, I know.... but I may not always run 16.5" wheels, and cost comes into play as well.


The 60 I got is missing both calipers, needs new rotors, and needs one caliper bracket replaced. All of that adds up to over $300 in parts alone.

I figure I can do the 3/4 ton brake swap for under $150 - and replacement parts will be cheaper down the road...

Has anyone actually done this swap, or is everyone just grinding the Dana 60 calipers? :confused:

dude .. stick with the 1 ton shit. i just bought all new stuff and its dirt cheap... and get 16.5 rims .the humvee ones are dirt cheap also...

I think you are going tohave a problem with the backing plate. I know you said modified but you will really have to modify it to make it fit on the 60 knuckle. none of the bolts will match up and the diameter is bigger on the 60. I dont know what dynatrac sell but it cant be cheap and that sounds like alot of work for crappier brakes.

I have a template of the Dynatrac caliper bracket they use when converting to 5 or 6 lug hubs on front Dana 60's - so there should be no problem there. Aside from that, I should just have to find a rotor that has the correct hat depth to place the caliper where it should go in relation to the rotor.

Still planning to try this before I fork over the $$$ to buy Dana 60 calipers with no cores, a new caliper bracket, and new Dana 60 rotors too....

i have some 60 stock rotors and caliper brackets laying around. yours for the taking. fyi they are from a dually front end, not sure if that matters.

I *think* there is a difference, but if not, I may just take you up on that :D

caliper brackets are the same. rotors are too with the exception that the single (non-budd) wheel rotors have a larger hole in them for the lug studs' shoulder. drill them to match and they will be identicle.
The dynatrac caliper bracket is of nearly no use to you. it is only good for the small 5/6 lug rotor the 8 lug rotors are a bigger od, and that bracket won't allow clearance for the caliper "pins" to clear the rotor.

Edit: what you can do, (I did) is use the 60 caliper bracket where it goes over the spindle, and graft it to a chevy 1/2 ton bracket to hold the smaller caliper, spaced exactly where you want it. ie only use the bolt pattern from the 1ton and only use the caliper retaining area from the 1/2 ton. custom built in your garage!

You might ant to check with JB's 4x4. He did my axles and he is making a bracket that will bolt to a 60 and allow you to use 78' chevy 3/4 ton brake calipers and rotors. I clear 15" wheels. His web site is www.jbs4x4.com.
