D52 Caliper Rear Disc Brake Brackets

[68 TT]

I have seen some newer AWD Astro vans with six lug wheels (the same wheels that came on my 03 Tahoe) so I am assuming they are a 2003 model year or so. Have you looked into using the D52 brackets with these rotors on a 4x4 application?

They are 1.14" thick and 12" diameter so I don't know if the D52 caliper can handle that for sure. You would think that 1/10th of an inch smaller would be OK.

I guess I haven't paid much attention to the newer Astros. I'll have to check into those and see what style of parts are used. I do already have something in mind for a 6 lug rear disc, but I'm reluctant as I'm not sure how well they would sell. Thanks for the info....

I will be your guinea pig on the 6-lug rear disc if you want.

My 67 is sitting on a square body 4x4 half ton chassis so it is 6-lug and I have a set of the El Dorado rear calipers.

I was thinking that the 88-98 new body style 4x4 slip on front rotors might work for this. I keep meaning to grab a set from Pull & Save to test out but always run out of time when I am out there. I will look them up on NAPA's site and get some idea of the offset and thickness to see if it is even worth picking up a set to test out.

Yeah I was planning on using the '88-'98 K1500 rotors. I've already got the dimensions on them and the brackets will be this style, just a different spacer. I might see about ordering some spacers cut for these this week.

The rear rotors on my 03 Tahoe might be an option too if your wheels can clear 13" rotors. They have more rotor offset so they might push the caliper out of the wheel far enough to make them work with 15" wheels.

Yeah I've found similar ones from the Savanaha vans. The only problem with putting say a 13" rotor on the back is that you really should run one on the front as big or bigger. That is where it becomes a little more involved and $$. Those Tahoe rotors are really deep.....about 1/2" deeper than the Astro rotors.

The matched front rotors on the Tahoe are only 12.0" diameter. I wonder why they are not bigger than the rear or at least the same size?

Turns out the rotors on the front of the 03 Tahoe are the exact same ones on the Astro van of the same year. Makes them a whole lot more common and easier to find.

got my brackets, i need the years for the parts that i need. like rotors, calipers and things of that nature

I've been cruising Autozone checking for parts and I'm a little confused. I keep reading the d52's are on 71-87 trucks but the parts differ on AZ's website. I did run across a note on the 84' calipers that says it is for J5 brake system. Is this what we would use?

Or will the ones they show for my truck work, I have a 78?

Do you offer a bracket for Dana 60's from 72 C20 using caddy Eldorado calipers? Thanks. Jim
