anyone have pictures of how the e-brake cables mount to these calipers and what cables to use?

[BIGJOEGS]

I received my brackets today and they look great. Also I told John I needed these brackets as soon as possible because I had my truck on stands waiting to finish the install and he went out of his way to get the to me asap.

Thanks again John I really appreciate the great service and product.

Bob. The brackets I made for you do not utilize D52 calipers. They use D154 calipers which are similar but smaller. Did your calipers come with the levers, cable brackets and springs? The cable housing attaches to the cable bracket with a clip and the cable itself goes up thru thru spring and connects to the notch in the lever.

Thank you for the purchase Joe

Thanks Capt, I'll email you a pic of what I have.

Capt, looking for a set of brackets for a 68 C10, purchased the 5 on 5 axle conversion from summit, would like to upgrade with these at the same time. Let me know how to pay

Won't these brakes cause pad knockback on the 12-bolt?

[Captainfab]

What do you mean by "pad knockback"?

This is when the rotor deflects slightly, pushing the pad and piston in with it -- the result is less braking power until the brakes are actuated again. This site does a good job explaining but seems to be missing illustrations:
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.

[Captainfab]

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.

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.

[Captainfab]

No. Those are the smaller Metric calipers. Only the '76-'79 calipers as stated in this thread.

Hey capt I'm interested in a set of your brackets can you send me an incoice. Are these in stock ready to ship? Thanx

[Captainfab]

No I do not have a set ready to ship. I do have the parts for them, that will have to be cleaned up and finished. I will send you a PM with ordering and payment info.

Hey captin I just paid through paypal. Can you let me know when you ship them so I can look out for them thanx. Jose

[Captainfab]

If you have your PayPal settings turned on, you will receive an automatic shipped notice along with the tracking number. I should be able to ship your D52 brackets tomorrow.

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]

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

[Captainfab]

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