6 Lug Rear Discs With 15" Wheels

[TypeSL2]

I would like to be considered for one of the first sets. Gotta get the truck back on the ground before the HOA says anything. Trying to build this truck without getting any fines. I have cash in hand.

Also, will the e-brake caliper still be the 93-97 f-body caliper as in your previous adapter plates?

[Captainfab]

No they will not use those calipers

Captain, do you still have these brackets available? Did I understand your descripton correct, I will be able to use my stock 15s and have rear disc brakes?

I was reading several different posts on front disc brake conversions, do you have any suggestions on ways to convert to disc in the front using parts found at my local auto parts supplier?

By the way, big props on your contributions to us fellow forum members!

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-'98 K1500 Silverado or Suburban front rotors. The calipers used on this conversion are referred to as the D369 calipers. These are also found on the '88-'98 K1500's as well as the C1500's. A complete parts list with part numbers is included with the brackets.


The cost on this set of brackets with installation hardware is $177.50. Satin black powder coating is an additional $28.00. Shipping within the USA is a flat $11.65. 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, you can send me a PM here on the forum or you can email me at captainfab454 at hotmail dot com.

Yes these brackets are still available. Would you like a set in bare steel or satin black powder coat? These will work with 15" disc brake compatible wheels.

Aside from the spindles and aftermarket 6 lug rotors, you can convert to front disc brakes by using '73-'87 components.

There are a few disc brake conversion threads in the '60-'66 FAQ index.

Captain, that's part of my problem...I was trying to find a way to make disc brakes work with my factory wheels. I've found (2) wheels that are from 88-98, but they won't work on the rear. They will only work on the front once I covert to disc brakes. I'm guessing I will need to have the wheel centers machined to fit the larger center hub.

what is the outside diameter of the smallest rear 6 lug disc setup you have?
weather it be E-brake on non E-brake.
My rear rims are 12 inches and have 7 inches of backspace.....

thanks CAPT.

[Captainfab]

I will have to get you a measurement tomorrow night after I get home from the shop. They both work with 15" diameter disc brake compatible wheels.

Captain,
would it be possibly to purchase only the main caliper bracket as to be used in a weld on configuration? Understandable if not. I just prefer welded on caliper brackets.

Thanks!

I am currently out of the caliper brackets for this set, but I do have a couple sets that were used during R&D and were not quite what I was wanting. You could likely make those work since you will be welding them on. Let me know.

I will be on vacation from 08-08-16 thru 08-25-16. If you wish to make a purchase you can post here in this for sale thread, send me a PM or an email to captainfab454@hotmail.com. I will reply to your inquiry when I return on the 25th. I do currently have a list of orders to build and ship when I return but I will add your name to the list in order of when received. Thanks for your understanding.

any modifications necessary to a hydroboost setup? All I did was replace the booster and master cylinder on my '72 4x4. Will it run your kit?

[Captainfab]

Whether you run a vacuum booster or hydroboost, it has no affect on the operation of two calipers and two wheel cylinders, or four calipers. You do need the correct master cylinder and proportioning valve, or an adjustable proportioning valve for either a disc/drum or disc/disc brake system.

[mister.freeze]

how can I tell which proportioning valve I have? (The more I think about it, pretty sure I just changed the booster & kept the master cylinder.)

[Captainfab]

I have no idea how to tell just by looking at one. The difference is internal. If it is the original to your truck it will be a disc/drum proportioning valve. You can try using that and then installing an adjustable valve in the rear line and see if you can dial in the braking bias that way. Some guys prefer to do it that way.

Hi captainfab did you ever make a rear disc brake bracket with e-brake that will work with 15in wheels

[Captainfab]

Yes I did a while ago. Here is the for sale thread.

Hi,

I'm fairly new to the forum. I have a 71 C30 and while it has factory disc, I wanted to upgrade to larger discs. It has 8 lugs of course. I am upgrading to 18 inch wheels. I have a set of 4 piston brembos I took off of a new Camaro SS that was upgrading to 6 piston. I would like to use these up front with either 13 or 14 in rotors

Do you have anything like that?

Thanks

[Captainfab]

Sorry but no I do not make anything like that. I don't think you will be able to find an 8 lug rotor thin enough to use those Brembo calipers on.

Bought your setup and machined axles down and rotors work great. With the 7/16 studs there is a lot of space on the wheel stud openings. At the start of post you suggested 1/2 studs. Any idea on application or part #.

Bracket setup is nice!!

I am officially notifying everyone that I will be on vacation from 02-05-18 thru 02-13-18. I will do my best to get all orders built and shipped before I leave, if placed by 01-31-18. Orders placed while I am gone will be built and shipped in order of receipt of payment once I return. Thanks for understanding.

Will adding these breaks change the track width?
