I haven't bought the Eldorado calipers myself, but I have read that they don't come with the arms for the e-brake. Some guys have made their own using the correct size wrench. If you get a set of the Eldorado calipers and they don't come with the arms, and you can't get the issue solved, let me know and I'll get you taken care of.

BTW, your brackets shipped today. You should see them Saturday or Monday at the latest. Thanks again.

Are there parts that will ultimately have to be found used or in a junkyard? I was planning on not running an e-brake, but it hadn't occurred to me that it was necessary for the state safety inspection, so I'll have to go with the Caddy calipers it looks like. Anyone had an experience with finding the Caddy calipers new with the e-brake setup? I don't actually think that for the safety inspection that they usually even check the e-brake, but I'd rather be safe than sorry and not be able to pass inspection sometime down the road.

I got the shipping info today, I appreciate it. As far as the calipers go, I haven't taken a look at any yet in person, so I'm not familiar with them. If anyone has any photos of what they look like in stock form and with a fabbed e-brake set up, that would be awesome. When you say with the correct size wrench, what exactly are you referring to? Sorry for being so in the dark about it all, like I said, I haven't had the calipers in my hands to see for myself yet.

I have a set of the Eldorado calipers at home. I will dig them out and post some pics of them this weekend.

That would be fantastic! And if you'd care to sell them...I know a guy in Texas that would probably take them off your hands.

I have three projects of my own fighting over which one will get the Eldorado calipers I have. I will let you know if I come across any more.

I completely understand that. I will be more than thankful just to get some good pictures of them. May head over to the junkyard in a bit and see if I can get lucky enough to find a set.

capt. fab,

i have assembled my rear disc brake kit(d-52 style) and noticed the outer pad is dragging on the rotor hat. is this normal, or should i be concerned? looking at your post of the installed pads it looks like yours are touching as well. is this going to create a singing noise or a vibration in the braking system? thanks again.

Can you post some other angles of that? Particularly the e-brake bracket...many thanks!

Re: D52 Caliper Rear Disc Brake Brackets
 
Did you also put longer wheel studs in?

Captainfab 10-31-2010 10:19 PM

Re: D52 Caliper Rear Disc Brake Brackets
 
The assembled brackets shown in the pics were the prototype's. And yes the pads were touching the 'hat' of the rotor. After seeing that issue, I made the caliper brackets 1/16" longer to move the caliper farther from center. This is the first that I've heard of anyone having the pads touching the 'hat of the rotor. I suppose there is a certain amount of variances with different pad manufacturers. I don't know if this would create any noises or issues. Do you have a way to grind down the flange on the pads where they touch?

Re: D52 Caliper Rear Disc Brake Brackets
 
i resolved the issue by clearancing the contact area of the pad on the caliper itself. i think by grinding the pad i was not resolving the issue. by clearancing the caliper i now can replace the pads without any issue in the future. i only have about .040 clearance. since this is a floating caliper i think it will be fine. i tweaked the mounting tabs of the pads to pull it tight against the caliper not not let is float as much. seems to look o.k. i used a napa brand semi metalic pad.

Re: D52 Caliper Rear Disc Brake Brackets
 
These look awesome and I will be getting a set in the future. I just want to make sure of one thing. I can use my stock master cylinder and just add an adjustable proportioning valve and they should work fine, correct?

Captainfab 12-03-2010 12:50 AM

Re: D52 Caliper Rear Disc Brake Brackets
 
Some guys get away with doing that, but it isn't the correct master cylinder to use. Since you're replacing the rear wheel cylinders with calipers, you need more volume to the rear. So the best master cylinder to use is one designed for a disc/disc brake system. Then you can either install a disc/disc proportioning valve, or install an adjustable proportioning valve in the rear line. The Wilwood unit I posted a pic of above is a nice all in one unit.

Anyone ever come up with any more e-brake solutions other than the Caddy calipers?

Captainfab 01-07-2011 12:36 AM

Re: D52 Caliper Rear Disc Brake Brackets
 
I've been looking into the possibility of adding another caliper to the assembly that is mechanically operated.

Greetings Captain,

Is there any problem with redrilling the disc to retain the 6 bolt pattern? I want to keep my truck pattern on my '70.

Thanks,

Greywolf200 01-30-2011 11:23 AM

Re: D52 Caliper Rear Disc Brake Brackets
 
I just ran across an article that said that the rear disc for a 14 bolt diff has the ebrake and the same fit as the Eldorado. Do you know anything about this?

Thanks'

Captainfab 01-31-2011 12:07 AM

Re: D52 Caliper Rear Disc Brake Brackets
 
Redrilling a 5 hole rotor to a 6 hole rotor may be a little tricky. One of the holes for the 6 x 5.5" hole pattern overlaps one of the 5 x5 holes. So at least that one hole will need to be filled.

Just bare with me a few days and I should have something for you later this week on a 6 hole rear disc conversion.

I've not heard this about the rear calipers for the later model 14 bolts. I'll check into that. Do you have a link to this article?

Re: D52 Caliper Rear Disc Brake Brackets
 
Rule #1----Don't believe everything you read on the internet!

I checked into the story about the Eldorado caliper on the 14 bolt axle. It seems he needed a caliper on the front of his truck and tried it and it fit(apparently an older truck) and there you go....... He published it on the internet, I guess because Eldorado rear calipers are so easy to find when you need a caliper for your truck.

Sorry for the goose,

captinfab, i plan on ordering your brackes soon and will be using the wilwood calipers on all four corners. I am going to be running 15x6 stock steel wheels. Will they clear the calipers with no rubbing issues??

Captainfab 02-12-2011 05:47 PM

Re: D52 Caliper Rear Disc Brake Brackets
 
The only wheel I have fit up on this rear disc conversion is a 15 x 8 Rally wheel. As long as your wheels are disc brake compatable, I don't see why they wouldn't clear the calipers.

Hello Captain,

I did a little brousing and it looks like a '96 K1500 6 bolt rotor will work with your set up if you make the spacer 5/8" thinner.

I replied to your post in the 6 lug rotor thread.

so is the application on the rotors for the front or rear???

Captainfab 03-06-2011 12:15 AM

Re: D52 Caliper Rear Disc Brake Brackets
 
They are the fronts for the AWD Astro/Safari's. They didn't come with 4 wheel discs until 2003-2005. At which time they were a 6x5.5" wheel bolt pattern.

If you need a E-brake these can be found under the application of rear calipers for the '76-'78 Cadillac Eldorado. The A1 Cardone part numbers for these are 16-4116 and 16-4117. Those are loaded calipers.

that right there is what i want on my truck the 76 78 eddorado calipers with e brake cables so i need these brackets in order to fit the caddilac calipers right? once agian rewally sorry for how man questions i am askin
