Rear Brake Disc Conversion

[diplo 10]

Hi, I have been on this board for quite a while and just recently I finally got the 69 fastback I have been looking for the last 10 years. It came with a partial 4 disc brake conversion from Stainless Steel Brake Company. I am in the process of finishing up the backs and have a couple of questions. First, how do you remove the parking brake cable form the drum housing?? My second question is about the brake lines. The kit came with pre bent stainless brake line that was supposed to fit like the old lines. When I went to put the back line on between the 2 rear discs it seemed to be way to long. Does anyone have pictures of how thier brake lines are routed that they can post? Thanks for your help!

It's been my observation that pre-fadded brake lines, more often than not, do not fit well. The best way to get lines that actually fit is to simply make them yourself.

 

The hard line pictured on this '80 Monarch 9-inch rear with Cobra rear brakes started out as a straight 60" length of 3/16" brake line tubing. I cut, bent, and double flared the tubing to fit the housing and the rear discs I added.

Hi Diplo,

 

I started with a straight 60" stick of 3/16" brake line tubing, and made the brake line across the 9-inch rear end housing to connect to the Cobra rear discs I have on it.

 

I installed new 7/16"-24 inverted flare fittings on the ends of the tubing.

For some reason, MOST parts stores do not carry the 7/16"-24 brake line fittings for 3/16" brake tubing. This pretty much forces you to use adapters. The bad part with that is it doesn't make for clean looking installations, but even more, every connection point in the bake system is just another point for a potential leak to occur.

 

If you cannot locate the correct line fittings locally, I have brand new fittings available through my website.

Hey Steve, I had planned on buying some SN95 braided lines for the caliper to hard line connection using your brackets I bought and GT calipers. I assume this would work the same as the factory lines but guess I'll need the adapters as well?

 

Diplo,

You can shorten the existing lines with a low cost tube cutter and a double flaring tool. I understand stainless is a lot harder to bend but you might be able to loop up the extra line to make a nice transition and make it look cool at the same time.

 

Also I just used a screwdriver and some channel locks to get the spring holder that locks the ebrake cable into the drum to release. It's not too bad with the shoes, etc removed from the drum.

The braided lines should have the same 7/16"-24 female threads as the stock factory hoses. If that is the case, then you would need the male 7/16"-24 inverted flare nut fittings.

 

Bending stainless lines isn't so much a problem as trying to double flare them without cracking the flare.

 

An easy way I've found to remove the parking brake cable from the hole in the drum's backing plate is to put a small diameter hose clamp around the barbs, and compress the barbs just enough to pull the cable through the hole.
