My rear 8 lug Ford d60ff is gettig disc'd. What rotors do I want, standard late 70's Ford front d60 units? Or is there a "wiser" solution?

cm "mmm, 4 piston calipers" k

Most people use 3/4 ton Dana 44 front rotors and corresponding calipers... I know I am :)

On mine I tried the method of grinding the hub down around the lugs to fit a particular Dodge 8lug disc "over" the hub instead of "behind" the hub, but it didnt appear to mount quite flush w/hub. So I tried my D60 front rotors which I think would have been the best offset because I wanted to mount the caliper plates to the stock "flange". BUT I couldnt exactly verify because the D60 rotor is much thicker than the 3/4ton type & couldnt fit the caliper over it without machining the rotor down or the pads themselves. This was all bescause I didnt want to just weld the bracket to the housing, I wanted to bolt it on as well, but I had to make a spacer too so I can feel comfortable using Ebrake calipers.:D

I've already cut the tubes down to get the WMS-WMS dimension I want, so mounting them outboard of the hubs is out of question. They'll be going inboard of the hubs, like stock.

Since I'll be going with racecar 4 piston calipers hanging from weld on mounts, the calipers will be chosen/sized to fit the rotors.

So far, 3/4 ton d44 8 lug rotors seem to be the way to go.

Anyone else?

Is there any advantage to using Chevy or Ford 3/4 ton rotors?

There was a big thread a while back on rotor differences - hat offsets and stuff. What I remember was the above.

I was the one who posted the dimensions between the Chevy and Ford rotors. Search for "3/4 ton rotors Chevy vs Ford vs Dodge" or something like that under my user name.

Basically you need which ever rotors you think will fit your bracket location. The Ford rotors have 0.4" more offset than the Chevy. Since you are welding on your brackets, I would use the cheapest rotor. However, the more offset you have the farther inward your calipers will be which makes more clearance for your rims and calipers.

If I remember correct most guys were using eldorado calipers? anyone know the PN or year of eldo was most commonly used
(I guess I could use the search.......Ill try that now) :flipoff2:

76-78 calipers had the 7-1/16" pin spacing.

Thanks Eric, I found the thread.

I think for the smallest package size, I'll go with the Chevy's with the shorter offset. Caliper clearance shouldn't be an issue with 17" wheels.

These guys have the caliper brackets you will need to weld to the housing: http://www.aa-mfg.com/

I used 3/4 ton 75 chevy 4x4 front rotors on my hybrid rear axle. inboard of the 14 bolt hubs, and used the existing wheel studs (used steel wheels, not aluminum so the depth taken off by the thickness of the rotor is not an issue as compared to using thicker hubbed aluminum wheels)

I am using 79 Ford 4x4 front 60 rotors

with part #'s.

I used 82 Ford 1 ton front rotors and 81 Corvette front 4 piston calipers.
I drilled the rotors to 11/16 and the hubs to 5/8 and pressed in 5/8 studs from an 83 Dodge 1 ton w'SRW.
I'm in the process of machining a set of bolt on brackets.
If I knew how to re-size pictures, I have a few shots that I could post up. :mad:
I have all the P/N's if you need them.

Are the demansions the same and the parts going to work the same on a dana 70?

Ok, here is the recipe for disc brakes, with pull off rotors for easy brake changes. This works for D60s with the big inner bearings and D70s.

Use the hubs off of late model Ford Econoline Vans (2002), along with the rotors and calipers.
All brand new, easy to find parts, 8 on 6.5", slide off rotors, one ton brakes.:flipoff2:
