I'll take a set and just found you do brackets for the six lug disc brakes for the rear using 15" tires and would like a set also.

Do you want 2 sets of rear disc brackets, or just one?

CapitanFab -- Installing in the next few weeks :) Are these the calipers you recommended in your previous post?

Those look identical to the ones I put on my truck using this kit. I don't know that company, so it may be a cheap chinese knockoff. They may be great quality. The ones I ordered were actually not assembled properly, so I kept blowing out the seal in the right rear. It was missing a copper washer inside the caliper.

Those appear to be the correct calipers. You might contact them prior to purchasing and inquire about the country of origin and or warranties.

wanting a set of brackets powder coated. Has anyone actually finished the conversion? any input/response? I would prefer disc/disc valve so I dont have to worry about adjusting the pressure and having my rear tires stop sooner or slower than the front... does anyone have a disc/disc valve that was basically plug and play for our trucks?

Captainfab 09-01-2015 11:51 PM

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 
I'll send you a PM with ordering info.

If you don't get a response here regarding the proportioning valve, you might try the for sale threads for the other 4 rear disc brackets that I make.

EDIT: I tried to send you a PM but your inbox is full.

In your first post you mention that 3rd gen F-body calipers will also work. Which ones are those? The 1985 -1992 ones like ACDELCO 18FR972 ?

Captainfab 01-17-2018 12:12 AM

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 
The 1985-92 F-Bodies are the third Gen, and the 18FR972 is what comes up when searching for those rear calipers, but the picture is not correct. The picture looks like the '93-'97 F-body rear calipers. I will have to do some more searching and get back to you.

OK, in that case it is probably the caliper ACDELCO 18FR790 used from 1982-88.

Captainfab 01-18-2018 12:13 AM

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 
Yes that is the correct caliper.

Would these work on a 1960? or could they be modified to work? I think I need to get rid of my rear drums...

Captainfab 03-21-2018 10:55 PM

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 
None of my rear disc brackets are a direct bolt on to the Eaton HO32/33 differential. I imagine they could be made to work if you want to spend the time and money to do so. Personally if you want rear disc brakes I would replace the Eaton with a '64-'82 truck 12 bolt with a better gear ratio and then add your rear disc brakes.

I guess I don't understand how they attach, Is it just modifying the mounting or is the axle whats going to cause the issue?

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 
All of my rear disc conversion brackets attach using the original backing plate flange. The Eaton HO32/33 has a different flange that the truck 12 bolt. Plus I do not know of the brake offset is the same. If they are not the same offset, the caliper will not line up with the rotor.

I picked up a 12 bolt out of a 70 Chevelle, would this kit fit? I am special ordering the axles and will have the flange cut down.

I'm not even going to pretend that I can answer your question..

however I was just reading this recently and it may be useful to you..

good luck!

12 bolt truck rear end vs 12 bolt car

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 
The car 12 bolt has a different backing plate flange shape size and hole pattern than the truck/Impala backing plate flange. I do happen to have a couple car 12 bolt base plates that I could substitute. So you are having axles made for a car 12 bolt with the 6 x 5.5" wheel stud pattern? I would think that a '70 Chevelle 12 bolt would bring a premium price.

Are you going to need a set of trailing arm mounts also?

Yes, I am having Moser make a pair of somewhat custom axles for it.

I am halfway thru removing the Chevelle mounts and will absolutely need a trailing arm mounts.

I picked it up a Super Chevy for $600, it's open with 2.73? gears. I think it's a good deal.
