6 Lug Rear Disc with 15" Wheels and an E-Brake
 

This set of brackets will allow you to have rear disc brakes on your 6 x 5.5 bolt pattern ’64-’87 GM truck 10 and 12 bolt rear differentials, and be able to run 15" wheels and also have an e-brake. This rear disc conversion is completely bolt on with one exception. The drum/wheel register will need machined down to approximately 3.06”. I do recommend upgrading to ½” wheel studs at this time, but it isn’t absolutely necessary for the installation.The rotors used with these brackets as well as the calipers are easily found at your local auto parts supplier. The basic application for the rotors is '88-'91 K1500 Silverado front rotors without F44 suspension. The calipers used on this conversion are the rear calipers used on the '79-'85 Eldorado, Riveria and Toronado as well as the 3rd gen F-bodies (I will get more specifics on those later). A complete parts list with part numbers is included with the brackets.

The cost on this set of brackets with installation hardware is $179.50. Satin black powder coating is an additional $28.00. Shipping within the USA is a flat $16.25. This pricing is always current and up to date. If you are outside of the USA, contact me for a shipping cost. For payments I accept PayPal and money orders. Credit card payments can be made thru PayPal. To place an order, post in this thread, send me a PM or send an email to captainfab454@hotmail.com, and I will give you the ordering and payment instructions and current lead time.

Here are some assembled pics. These 3 pics are with a typical '78+ metric front caliper.

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

These pics are with the '79-'85 Eldorado, Riveria, Toronado rear caliper. This particular one is the wrong one for that side, but it was all I had at the moment to check for fitment

I want a set. Do I paypal you the $161.65?

Yes, PayPal works. I replied to your PM :)

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

Nice! I'd love a set. My question is- would this rear disc setup pair well with stock 71-87 front discs? Or do I need to upgrade? Do I need to swap master cylinders or proportioning valves?

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

This rear disc conversion will work fine with a stock type '71-'87 front disc conversion, but you will have 5 lug on the front and 6 on the rear. Yes you need to change the master cylinder to a disc/disc master and the proportioning valve needs to be either a fixed disc/disc valve or an adjustable valve in the rear circuit.

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

i'm down for a pair, sign me up ;)

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

Very nice. Do stock e brake cables work or how does the e brake set up work. Sorry for dumb questions. Thanks.

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

Sorry, 2 more. Does this alter the track of the rear wheels or the pitch between them and does the std 4" backspacing that are on 8 inch 6 lug rims like 15x8" steelies or ralleys fit.
Thanks again.

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

I haven't installed any of these, so I do not have an exact answer to that question. I doubt that the stock drum brake cables will work, but I imagine it might be possible. Typically a custom length cable needs to be made, unless someone knows of an OEM application that works.

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

Yes this disc brake conversion will increase your track width aprox 3/8-1/2". As long as you are using disc brake compatable wheels I do not see a problem. I have not checked fitment of any wheels yet. I can do that in the next couple days.

I will send you a PM with payment info.

Here is a link to the correct calipers on Speedway.

Keep in mind that you will need a left and a right.

I tried to add a pic to post #1 but I am past the time limit to edit. So here is a pic of what I am selling in this thread.

And how they look installed on the truck.

Capitanfab -- very interested in a set of these. Especially since Im within the first 6 to respond.

***The first 6 members to post here in this thread will pay only $150.00 for bare steel brackets plus shipping of $11.65***

How would you like payment? Also looking for a hydraulic clutch bracket for my 1970. Will the 60-62 with clutch work for me?

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

I will send you a PM with payment info.

No the booster bracket hydraulic clutch for the '60-'62 will not work for a '67-'72. As I posted in your thread, I make a booster bracket with a hydraulic clutch conversion specifically for the '67-'72 trucks.

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

I would love to get a set for my 1961 stepside. I Posting here to get the

" ***The first 6 members to post here in this thread will pay only $150.00 for bare steel brackets plus shipping of $11.65*** " deal

Still in effect correct? Do you have any custom e-brake cable kits you recommend?

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

I am assuming that you have changed out your original differential for a 12 bolt or a 8.5" 10 bolt?

I'm not sure who is making custom e-brake cables since Inlinetube quit making them a few months ago.

I will send you a PM with ordering and payment info.

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

The first 6 sets at a discount have been sold.

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

So these will work with the 15" steelie disc brake wheels (4 nub) or no? If so I am interested in a set

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

I don't see a problem with fitment. PM sent

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

New to this forum, but I'm interested in a set of these. I've got a '69 with a 12-bolt, 6 lug rear- running factory steel rims. I've seen others suggest that you could simply purchase new axles that would be ready to go with the rotors required with this system- does anyone have the associated P/N's for those or know where to get them? Also, has anyone discovered what sort of E-brake cables are required with this setup?

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

You can get 6 lug replacement axles from any vendor that specializes in differentials such as Randy's Ring and Pinion, or Toms Differentials, or from Summit Racing. Before purchasing axles just to have the correct flange OD for the rotors, I would verify the dimension of the axles being purchased.

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

Hey captain happy Easter
The rotors for this install are 88-91 k1500 they show 2 kinds. 1" and 1.29" version I haven't seen anything on the f44 version.
Do you happen to have part numbers and info like you have in your other post? I just want to get the info right and I will be ordering ASAP.
Can you help me out?
Thanks Scott

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

I don't have that parts list here on my home computer. The part numbers are on the list of parts that come with the brackets.

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

Ok I want to see the cost for me to go the rear disc route.

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake

Can you tell me the vehicle that the rotors are from?

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

The same application I state in post #1. They are for a '88-'91 K1500 without the F44 suspension.

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

Captainfab, kit came in yesterday. I will post pictures when installed. Thank you

Re: 6 Lug Rear Disc with 15" Wheels and an E-Brake
 

This was mocked up. Looks good way better than any drum. Will be a while before I get to test them out.
Thanks captain fab.
