For the rear alot of companys make a bracket so you can use 73+ K20 front caliper and disc. Only problem is you will lose you e-brake. Not sure if there is anything you can do on your front. The best option would be to go with a D60 the ford and chevy calipers are huge.

 

You can use 78' Eldarado calipers along with the above mentioned parts and retain your e-brake on the rear. As to the front get a D60. That D44 will not hold up if you wheel any. You have any pic's?

 

I already know about the rear. And you can retain your e-brake even with the K20 front brakes. I've done it b4.

The D44 holds up pretty well to the 39.5s. It has upgraded shafts and u-joints and a HD LSD diff. Never had a problem out of it. I'm going to upgrade to a D60 just for the brakes.

I just wasn't sure if there were any big brake kits for the D44 or D60.

Here are some pics.

 

D60 rotors are the same size as the D44. About the only "extra" performance you'll get is to use calipers from a F*rd D60. They use a dual piston caliper as opposed to GM's single piston, or you could order an aftermarket axle.....:muahaha:

 

I had asked this question once before and got that nobody make bigger brakes for a D60 front axle. I even called around and the general consensus was that the stock brakes do a good job.

I got to thinking, wouldn't all you needed was a different mounting bracket? So buy a good set of calipers and roters(that match your bolt pattern) and get a machining company to fab a bracket for the calipers? Or would this be out of the question because their is something that I am not seeing here?

I've never seen where someone upgraded it other than the Ford dual piston calipers. I assume it could be done with the appropriate amount of money.

For our application, it's not that a better rotor isn't ideal, it just won't fit. Part of the equation for better braking is that you need a rotor that's larger in diameter, and guys that tow or four wheel usually stick to the same size wheels as were offered. You do have a few that upgrade to a size larger wheel, but they are the minority, so brake companies never saw it as a profitable venture.

With a hydroboost system, good brake pads, and 44" Super Swampers, those factory rotors do rather well from what I've seen.

 

I'm thinking its the D44 that is giving me problems. My last truck was a '94 Suburban 2500 w/ 454 and it had a D60/14BFF combo with 44" swampers and would stop very very quickly.

I think I'm just gona try the D60/14BFF combo with discs front/rear and hope that the braking improves. If not then it looks like I'm going to figure something else out.

And besides, these wheels are only temporary. I've got 20s going on it very soon.

 

Good luck with it bud! Let us know if you find anything out. I know some crawlin guys, myself included, that would be interested in knowing.

 

I have a trooper(~5.5K loaded) with a D60/14b and 38.5sx on steel rims(heavier than 39.5 Iroks). I have stock 60 brakes, k20 caliper/disking the rear, and a 1 1/4" bore master and small single diaphram vacuum booster. I have no problem locking up all four, but work perfect for normal stoping, too. I would think that this set up would work well for you.

There are 2 different size wheel cyls[piston dia.] for the 14 bolt FF, can't recall the exact sizes offhand. Have your parts house look it up for you. The larger cyls might be what you need for the big tires.

P.S. I had an ex glass truck that had an "H" rack and was loaded all the time, had to go with the smaller cyls 'cause the brakes wanted to lock up with no load after the rack was removed.

 

My 67' Truggy has a D60/Eaton with 4wheel disc's and it will slide all 4 tires when I get in the brakes hard. I'm very pleased with the rear disc's. BTW cool truck.
