My Dana 70 disc brake conversion (W/ Pics & Questions)

[Gravel Maker]

The force isn't coming downward......

Yes, the 14 bolt and D70HD flange is the same. The only real diff between the two is the D70HD uses studs and nut whereas the 14 bolt is threaded.

Gravel Maker, if you went with a greater bend would it be necessary to gusset it?

The force is from the lateral direction with the entire width of the 3/8" bracket, a gusset should not be needed. The real question is can we bend it clean enough and I think we can, our 3 legged links are 3/8" and bent at a 90 degree angle just fine. I will look into it.

How many are using D70's, I am not seeing too many on the trails yet?

Gravel Maker,
I'm new here, but I just picked up a D70 and was looking into disc for it.

Thanks

Kert at DIY4x has brackets for the 52's so that you do not need to move your upper shackle mount in the frame. I think they are like $150 for the pair, but it saves you a lot of work.

Yep, you don't need to move the shackle hanger in the frame. We've also done tapped flanges for the d70 axle for the disc conversion.

I would like to put discs on my Ford DRW D70 when the drum brakes quit working.

We will be testing the prototype this week....

If it works fine the first try they will be available within 2 weeks.

Thats still an 1 1/2" more in the bend... thats alot of steel to leave unsupported in a BRAKE system...

I think you need to consider the direction the force is coming from.....

The force is not coming down on the bracket where the bend would be at risk, the force is coming with the bracket where the thickness is the width of the bracket itself......Also, the bend needed turned out to be much smaller than anticipated, only a hair over 50 degrees and they are still 3/8" thick. Detroit and Toyko do alot more with a lot less.
