Re: D52 Caliper Rear Disc Brake Brackets
 
Is this 'pad knockback' something you have experienced with your rear disc brakes? Did you purchase a set of these D52 brackets from me?

The D52 calipers are not solidly bolted to the caliper bracket. They do slide on the 'bolts' that connect them to the caliper bracket. Yes the axles in a semi floating differential do have some lateral movement. In a differential that is in good condition, that movement should be minimal. I have not had one complaint regarding 'pad knockback' from any of my 100+ customers that have bought any of my rear disc brackets.

http://www.stoptech.com/technical-su.../pad-knockback

On full-floating rears this isn't an issue, but with our 12 bolts there's some axle endplay that causes pad knockback. Floating calipers get around this with the ability to move with the hub. Fixed calipers like these do not. An alternative solution although not 100% effective is to use c-clip eliminators which hold the axle in place to a much greater degree.

So I guess the answer is that these calipers are ok if you are running c-clip eliminators.

My bad, I saw the first brake pic and it looks like the willwoods have front and back pistons which would make it a fixed caliper! Since these are floating I surmise that they'd work well without the c-clip eliminators.

Will the 1985 Cadillac Eldorado calipers fit? They ave e-brake as well.

Re: D52 Caliper Rear Disc Brake Brackets
 
No. Those are the smaller Metric calipers. Only the '76-'79 calipers as stated in this thread.

You wouldn't happen to have any pics of someone using this kit with a porterbuilt rear 4 link would you? I'm wanting to get a set of brackets but think I'm gonna have issues with the panhard bar bracket interfering with the caliper with my differential being narrowed 8.50 inches

Captainfab 02-22-2016 12:01 AM

Re: D52 Caliper Rear Disc Brake Brackets
 
Sorry but no I do not. No one sends me pictures. All there are, are what you see in this thread.

What about moving the caliper to the front of the differential?

No worries. I can modify the bracket if push comes to shove. I could do that more than likely but the bars aren't much further inboard than the panhard bar bracket

The inside surface of the caliper bracket will be 1-5/8" inside from the outside of the backing plate flange.

Re: D52 Caliper Rear Disc Brake Brackets
 
Ok thanks! Will do some measuring next time I'm out and I'll let you know. I think the brackets will fit but I'm. Pre worried about the calipers. I guess it all depends on how they will be clocked. I looked at the pics in the thread but it's hard to tell.

Re: D52 Caliper Rear Disc Brake Brackets
 
Got my "CaptainFab" brackets for my 69' stepside the other day. Machine work was excellent. I did not have any issues with fitment, everything lined up and went together perfect. Only issue I had was the pads were a little thick for the new rotors, I sanded the pads a little and caliper dropped in place then. Here is a couple of picks.....I put a coat of "POR" on the brackets....

Photobucket!!!!! Don't know what happened. anyway kit was great, Good Job Captain. Also, about the same time we had a 1963 c/10 at my repair shop for boost/mc add-on. We needed the bracket that mounts this set-up to the firewall. "CaptainFab" to the rescue once again. Bracket showed up couple days later and worked perfect......Casey

Captainfab: I've got the d52 kit on my 72 c10. My issue is the outer brake pads are dragging the circumference of the rotor on the horizontal surface (hub?? Between the rotor face and the wheel.). Is there a certain set of brake pads you reccomend? Or did I install something wrong?

How long ago did you purchase the D52 brackets? That issue arose quite some time ago, but I made a change to the caliper bracket to correct that.

Captainfab 05-19-2016 12:44 AM

Re: D52 Caliper Rear Disc Brake Brackets
 
I will confirm the date of the latest revision tomorrow, but I believe your brackets were before that. The interference issue is due to manufacturing tolerance differences in the aftermarket replacement rotors. Did you purchase the brackets in bare steel or satin black powder coat?

Bare steel, they were assembled on the truck then painted with the rest of the frame. I am running Napa rotors, is there a preferable brand that doesnt cause the interference?

Captainfab 05-20-2016 12:11 AM

Re: D52 Caliper Rear Disc Brake Brackets
 
I do not know of any specific rotors that are any different than others and no customers have let me know of any.

My latest revision of the caliper brackets was in October of 2014. So you do not have the revised brackets. If you will send me your shipping info, I will send you a set of the newest caliper brackets.

I think I solved the problem: popped the calipers off and bent the upper "fingers" on the outer pads downward and it seems to have solved the issue thus far. It pulled the pad up of the rotor hat. And there's about a 1/16th -1/8th inch clearance now. If the issue persists I may take you up on that offer. Thanks again!

Captainfab 05-20-2016 12:37 AM

Re: D52 Caliper Rear Disc Brake Brackets
 
OK. Hopefully those pads will stay in place up off of the rotor hat. If not let me know.

Re: D52 Caliper Rear Disc Brake Brackets
 
I have made a fatal mistake on my truck and cannot use your rear brake kit. My truck is a standard with a borg warner R10 overdrive which means my truck freewheels even with the truck in reverse and off. In other words I HAVE TO HAVE an e brake or my truck roles away in gear. I highly apologize and understand if you take some of the refund out for your troubles and fees. Please let me know if a refund is an issue. Again this is my fault and a public apology!

You apparently did not read page 1 of this for sale thread where the e-brake style of calipers are talked about.

Yes I read that but i do not want to use the caddie brakes. I have already purchased the D52's and now have to send the rears back as well. I dont want the mismatched brakes. To be honest it was more about looks than function for me.

He sells brackets for Camaro calipers as well which have e-brake.

Anything in the works for this same setup on a Ford 9"?

Captainfab 07-16-2016 11:31 PM

Re: D52 Caliper Rear Disc Brake Brackets
 
Sorry but no. If you are running stock Ford housing ends, just about everyone runs the Explorer rear disc assembly. If you are running a narrowed 9" with the correct Impala/truck housing ends, I have the correct base brackets that will retain the axle bearings and allow you to be able to run these D52 brackets.
