D52 Caliper Rear Disc Brake Brackets

[Captainfab]

No I do not. I have not found a 6 lug rotor that will accommodate the D52 caliper and pads.

Here are the 6 lug rear disc brackets that I do offer.

I replied to your PM, but your PM did not state which of my 5 rear disc brackets you were interested in.

Holy Wow! I got my brackets a few days ago, Amazing work Cap! Talk about BEEFY! Sorry for the delayed response but I have been busy with work. I’m gonna get these put on tomorrow and I’ll get some pics posted up when I can. Again, thank you and keep up the good work.

Good morning all, so I have the D-52 brackets going on my 85 this mor and this may sound like a stupid question but is there a specific orientation for them? I put the driver side on for the caliper to the rear of the axle with no problem, then move to the passenger side but the alignment doesn’t work that way. The thicker intermediate bracket only lines up with the outer “c” bracket if it’s mounted forward of the axle. I assumed they both went to the rear. Am I wrong? I’ve tried adjusting the “c” bracket but that doesn’t help. I have pics but not sure if they will load. Thanks.

[Suprmn78]

I found the problem. The intermediate bracket, the thickest one, is 4-1/2 inches wide on one side which allows for play against the back of the axle flange and 4-3/8 inches wide on the other which doesn’t allow for any play. Both brackets are this way. It’s as if the lazer cutter (or whatever was used) was not completely vertical while cutting them. I’ll take the one side to the shop and grind it down evenly and hopefully that works. It should. Just thought I’d give you a heads up Cap.

I also had to grind the inside of the intermediate bracket where it meets the axle flange, in order to get it to fit flush. aligning all the brackets was somewhat tricky. I chalked it up to small discrepancies in my particular axle. Also, had to grind down the “lip” of the outer pad, as it was grinding on the rotor hat.

*Pictures are turned funny, calipers are clocked in the correct position*

[Suprmn78]

Yep, went to the shop and used a micrometer to check it and after about half an hour of grinding, I got it to match the other side and boom! I have to order my calipers and pads tomorrow but hopefully they won’t give me any hassle with fitment. We shall see. I’m just glad in a way that I wasn’t the only one with this issue....I thought I was going crazy. Lol

[Captainfab]

I appreciate the feedback. That's the only wayI know if something isn't fitting correctly. I will check into the dimensional issue with the spacers. Yes they are cut with a 400 amp high def plasma on a Kinetic table. That is why they have a little taper to the cut.

[UATahoe]

Interested in a set of these brackets. Any changes necessary referencing the above?

[Captainfab]

I have started checking the cut taper on the spacers and correcting if needed.

Any thing for 88-98 available??

[Captainfab]

Sorry no, not yet. I still can't get all these local people to leave me alone so that I can work on new products and installation instructions. Which differential and what size of original drum brakes do you have?

Let me see what I can do about determining the brake offset. I haven't been able to find a definitive answer online. I should have it written down at the shop. If nothing else I will have to tear apart the '90 10 bolt I have at the shop.

I mounted my brackets ( awesome by the way ) and I bolted on my D52 Wilwood calipers and I have a question about the Wilwood brake shoes.... the inner shoe goes on with the bolt going through the hole in the shoe and is snug....... the outer shoe just has the tabs that rest on the calipers yet they are loose fitting? Should they be?

I don't have nay brake lines or anything hooked up yet and not sure if that makes a difference or not?? Do they tighten up once there's brake lines and pressure attached???

[Captainfab]

It has been many years since I have had hands on with the Wilwood dual piston calipers but I do not recall the outer shoe being loose. On a stock D52 caliper they are not loose. Have you contacted Wilwood about this issue?

[GMC Guy]

my outside pads aren’t super tight, but they work fine and don’t go anywhere while dragging slightly on the rotors
