It's typical for these aging cars to have components that are either barely functioning or practically turning to dust. Case in point, the factory brake lines found on our project El Camino were in no condition to use. While a portion of the rear brake lines were present, the lines to the front were completely missing. Additionally, the lines that were left behind had been rusted through and the end-fittings were completely unusable.Several months ago, we replaced the entire brake system with one from Master Power Brakes ("Brakes In A Box", page 40). It came with new 11-inch discs up front and a rear drum assembly with a power booster and master cylinder. What we didn't show you until now is that we never replaced the brake lines. Since the rear lines were in no condition to function properly and we were missing the front lines, it was obvious we needed a complete kit down the road.
The good news is that our search for new lines was an easy one by simply calling Inline Tube. If you weren't aware, Inline Tube specializes in factory-correct OEM or stainless lines for nearly any application you can think of. Their kits are manufactured with a CNC-bender and computer cut to ensure a guaranteed fit. If new brake lines are what you need, Inline is sure to stock them. While Inline Tube offers the standard OEM lines which would have sufficed, we upgraded to the stainless kit for a few extra bucks to resist potential corrosion. Our kit came with everything we needed, including nine stainless pre-bent brake lines, all of the necessary clips, unions, and a new rubber line that runs over the rearend to feed fluid to the rear brake lines

Unfortunately we were unable to remove most of the old lines by loosening the hardware. We ended up cutting most of the rear lines away with a set of wire cutters. This saved us time since we weren't going to be using any of the old hardware with the new stainless kit.
We started at the rear of the El Camino and worked our way forward to the master cylinder. Space is tight under the car, so any way of getting the car up will help when installing the new lines. It's also a good idea to start by laying out the each line underneath the chassis to help get a better visualization of where each line needs to be installed. All said and done, we only spent a couple of hours removing the old lines and running the new stainless kit, so follow along as we show you how to get the job done.

Fortunately it was easy for us to determine which lines attached to the rearend housing. Out of the box, they were zip-tied together and it was only a matter of threading the fitting of each line into the rear of the drum brake housing.

We used the original T-union bracket that attaches itself to the rearend cover and mocked up the new rubber line, bracket, and T-union. We tightened the T-union to the rubber line with a 5/8-inch wrench and a set of pliers. We then placed the bracket and rubber line above the rearend. We ran the rubber line through the rear crossmember. Again, we left the whole assembly loose for now. |
