C10 Rear Disc Swap w/ D52's (pt1) 

The install is finished and the video exists, but its a mostly unedited version which has some gaps in it from missing footage over the past summer. I'll put it up eventually, but I don't have much time to edit anymore and the truck is on other phases of the project. My IG has a few more recent updates from the summer which show a little bit more of the disc upgrade.

Wrong bolt pattern

Exactly,, wrong bolt patern,,

Tahoe probably has 6 lugs

My axles were held hostage at a failing machine shop, and after fighting for a couple months to get them back, they were basically destroyed by a hack machinist. I have everything sitting ready to go, but am waiting on my new set of custom Moser axles before I can finish the install.

@@REVJHD Wow! That really sucks. Sorry to hear it.

Hope to see you back soon.

Part 2???

I modified the bracket that held the booster to the firewall. The astro booster is designed to sit at a slight angle on the van firewall, which would make it point down on the c10. There are brackets that are designed for the swap now, but I just modified the face of the old bracket to remove the angle and sit flat. If I did it again I would either make a bracket from scratch, or buy one (mine works fine just isn't a pretty as it should be). I'm using the booster and master from the Astro, with the Wilwood D52's in front, stock d52s out back, a manual prop valve, and custom NiCo lines.

You can still run non-power brakes with front disc (my truck ran that way for a few years), just swap the prop valve so it doesn't lock the rear right away. With the correct non-power master cylinder, it will stop fine. If your using the master cylinder off a power-brakes truck, it will feel a bit low on stopping power (the piston/plunger on the power brake trucks has a different diameter).

@@REVJHD Ok Thanks SO Much, I also have a 2 wheel drive 69 3dr I am using for parts,, which has Disc on front, and it does have the Power Booster, But it looks like someone put it on there, and sure doesnt look like it is suppose to be there, so i did not want to use it, I will switch the Porp Valve once I get the axles switched! Thanks ALOT!!

The brackets only fit 12 bolt truck housings.

Winter, job change, and waiting for axles to be redrilled for oversize studs. I'll have the completion video and other updates on the truck a little further into spring. :)

A huge number of GM cars and trucks, it was the primary default caliper for most of the full-frame car era in the early 70's into the 90's. C10s, Caddy Eldorado's and others. The wilwoods bolt on the existing D52 bracketry, and will fit 15" + wheels (close fit on some 15's).

Captainfab! Guys can use the old 76-78 Eldorado rear caliper if they want e-brake. Cheaper alternative is a brake line lock.

REV J where did u order ur parts from because I couldn't find a captainfab website to order brackets and other parts??

He doesn't have a website, he's just a dude who builds C10 swap parts in his free hours at the machine shop, from what I remember. I've known him for a while, but the best way to find his stuff is to head over to the 67-72chevytrucks forums, and search his username. He's got ~15 products

@@REVJHD look thanks can u see his products on the forms? Idk anything about forms.

I was gonna say no, but I just discovered that CaptainFab actually has a website now (sort of). CustomFab-CDA he has the kit listed on the front page "D52 Rear Disc Brackets"

@@REVJHD thanks

E-brakes are for quitters.

@@REVJHD and your a fool not to have one! Better hope you don't have to have inspected, you would fail, then have to park it till you set up an E-brake. Willwood makes a kit to do just that, yes a few bucks but what is your life worth? Or there are GM rear calipers that have an E-brake that would bolt onto the brackets you are using.

E-brakes are for quitters? Yeah right! The E-brake was the ONLY way that I was able to stop my vehicle while doing 45 in traffic. I'm keeping my E-brakes.

I have the capt. Fab brackets and Gm calibers with e-brake , can’t get the 1.25 rotor to fit.Is there a 1 inch rotor with the big top hat that will work

CaptainFab. I don't have any current contact for him but I believe he still sells on the chevy truck forums and a few other places.

It was def. cheaper for me in this case, since I already had the D52 calipers from the front of the truck. I only had to buy the bracket, rotors, and hoses.
