DAMN those are good prices I just whipped out ecklers and that's half what they want

MSHax · 10-17-2013, 04:06 AM

damn cheap!

**steelhorse** · 10-17-2013, 08:06 AM

Good price.

chopnchaneled · 10-17-2013, 10:48 AM

Didn't say if their 5 or 6 lug, totaly different part # for either one on the next brake page?

**leddzepp** · 10-17-2013, 11:17 AM

I have heard nothing but good things about the eBay kit. It is complete with e brake too. A lot of these kits sold have calipers that have an e brake built in...BUT you are on your own when it comes to figuring out how to get the proper cables and route them to actually make the e brake WORK.

70blackfish · 10-17-2013, 11:33 AM

hummmmmm.......i need these

chopnchaneled · 10-18-2013, 09:14 AM

LeddZedd.......... Do you know if they are 6 lug or 5 lug?
Thanks

Picture shows 5 lug

eBay one says 5 on 5 rotors.

FLEET72 · 10-18-2013, 10:15 AM

Looking closer at the Classic Discount Parts kit is for 64-72 A Body, 67-69 F Body, 68-74 X Body. Not sure it will work for a Truck 12 bolt.

Andy4639 · 10-18-2013, 11:27 AM

E-bay add is 5 lug

Quote:

1963 - 1972 C10 rear disc brake conversion new 5 lug
5 lug 5 on 5 drilled and slotted rotors

This kit includes:

2- 5 lug rotors (5 on 5)

2- loaded calipers with emergency brake built in and semi metallic pads.

2- brake hoses, banjo bolts, and required copper washers

complete emergency brake kit- 3 cables and new hardware.

complete caliper mounting hardware kit. brackets and bolts.

I think I'm going with the ebay kit and this booster. http://www.ebay.com/itm/330948170536...536%26_rdc%3D1

davepl · 10-18-2013, 02:25 PM

Never done it on a truck, but adding rear discs to B-Bodies has been nothing but grief for me. Even with floating calipers the amount of slop allowed by a C-clip setup seems to really compromise the rear discs so that your brake effort first has to align the rotors within the calipers (or slide the calipers) before it does any actual braking.

That's the part I hate.

Anyhow, unless you're building for a road course, towing, or show points, rear drums are all you'd ever need.

But rear disks looks so much cooler than drums

Andy4639 · 10-18-2013, 03:51 PM

Well I haven't decided yet but after the 6.0 install I'm either doing a disc swap are a posi unit in the 71.

MSHax · 10-18-2013, 06:29 PM

Make sure to get a disc/disc proportioning valve.

This one comes with the booster.

MSHax · 10-18-2013, 06:45 PM

Cool deal. $200 for booster/master/prop seems cheap

Syndrome · 10-18-2013, 09:31 PM

You can get 5 or 6 lug from the ebay seller, he also has complete front+rear+boost kits for 1050+ shipping, or 1130 for the nickle plated booster.

I haven't tried them yet but a member by the name ' Pick ' said he ordered the 4 disc kit last week and is going to review them if anyone is interested.

Here's some pictures from his build thread.

Agent915 · 10-19-2013, 04:24 PM

What about sourcing the rear disc set up from a donor truck? Would that be a less expensive option? I don't recall what year model GM vehicles will interchange, but seems like I remember someone posting about it. Anyway, just a thought.

joel.e · 10-19-2013, 05:22 PM

here is a link to a rear set similar to ebay

http://www.autocityclassic.com/index...mart&Itemid=66

I got these at the Carlisle show. They bolt up fine but, as mentioned above, the ebrake doesn't come close to fitting even though they give you another ebrake cable. I also had to move the ebrake cable bracket on the trailing arm backwards to a pre-existing hole. 5 lug only I think.

I think others have found the front brake setup off an Astro/Safari van fits the rear of our trucks.

Yes, I have them and my initial impression is positive but I haven't started putting things together yet. I'm still trying to chip my way through the years of gunk and trying to make sure the stuff that stays is in good shape and ready for the new parts. At the moment it is just shiny stuff in boxes in my garage.
