1983 Camaro Z28 with transplanted 87 IROC 305 TPI. The original 83 drum brake rear end was swapped for a disc brake axle. From best guess its from a 86 GTA.
Trying to install the rear brakes. I have the passenger side brake hose bracket and the bracket to the "T" hose for the line that runs from the front. By what I have, I am missing some kind of bracket on the drivers side for the brake hose. My references (GM 82-92 Parts Manual, several online parts stores) show that the drivers rear brake line goes directly to the caliper. However, by what I got with the rear axle, this is not the case. See Photos.
The inlet hole on the caliper is on the bottom, with the arm for the emergency brake being in the way. I looked at several places that sell pre-bent lines, each show a direct straight connection to the caliper. Anyone have any information regarding this missing bracket. I thought about making my own lines, but staying close to original (?) is kind of my goal. I do want to go with stainless steel due to being in northeastern Ohio and the winter weather we get. The "T" block is bubble flair, so if I make my own lines, I think I would need 4mm stainless steel line instead of 3/16. Am I correct in this belief?

Any insight to this issue would be a great help \

Drivers Rear Brake Caliper

 

For some reason the, one of the photos does not show up in my original post.

 

I believe the earlier cars the hard line went to the caliper but the later cars had flex hoses on both sides. Just heads up, the 82-84(ish) cars use standard thread fittings and 84 1/2 and up were metric. So you'll need to get a little creative.

 

The driver's side iron caliper on 82-88 disc brake axles, 9-bolt and 10-bolt, came from the factory with a hard line from the T that goes directly into the caliper, like the picture I've attached below; no rubber hose, no bracket like the passenger side has. The passenger side has a hard line from the T to a rubber hose that join at a bracket that attaches where the hole is that you're showing. The driver's side aluminum caliper 89+ rear disc axles used a bracket and rubber hose like the passenger side.

If your disc brake axle came from an 86 TA (no GTA until 87), then it might be a 9-bolt, and if it is, then it might have the 3.70 axle ratio, which was only available in 85 and 86. If your axle came with a rubber hose for the driver's side caliper, then someone modified it to that.

If the aftermarket hard line for the driver's side is shown as straight, then it can be easily bent and shaped to make it fit around the parking brake hardware. The hard line in my picture was curled a couple of times from the factory, and I've bent and straightened it in all sorts of ways after removing it, and it wouldn't kink, so it's not a fragile as people think.

In the picture, you can see that the hard line is formed (bent/curled) to fit around and between the parking brake brackets and is routed in through the side. A rubber hose may or may not be easy to route around and through those brackets, which might answer the age-old question about why the driver's side was designed with a hard line instead of a rubber hose.

 

That it what everything is showing on how the drivers side rear brake is plumbed in. Thank you for the picture! So apparently this car is a Frankenstein when it comes to the rear brakes. I am wondering if this braking setup that was on there was a part of a performance package since Rock Auto shows rear disc brake hoses for performance package for Camaro's and Firebird's. If it was, then I am missing a bracket for the drivers side. The video I mentioned points out the bracket.so I might have to dig around for some more information.

I watched a video on YouTube and it shows the brackets and rubber hose on each.

The short brake lines and the rubber hoses (hoses not much good) that came with the rear end makes me believe that there was a factory setup. The hard lines may have been replaced at one time prior to me getting the rear end since they do not have the gravel guard on them. The gear ratio of the rear axle is stamped as GM14035665 13:42. I can be wrong about the year of the donor car. I am going to look into seeing who had pre-bent stainless lines that will fit.

Thanks for all the great information.
