Review on Roll Copper Nickel Brake Tubing by Stephen Thomas

I live in the "Rust Belt" and needed to replace the rusty, worn out rear brake lines on my 1996 Chevy Blazer. Please note that I am a "backyard locksmith" although I grew up with a father who has been in the automotive business his entire life and I know a great deal about auto restoration through experience and learning from others. Last year I used the infamous Polyarmor steel hoses sold at major auto parts stores to replace the fuel hoses on them and noticed that they already looked like they were starting to rust. I never used that crap again so I decided to try this product. Among other things, poly armor is expensive and I'd probably spend triple that on new lines in the back. So I wanted something not only better rust protection but also something cheaper, especially for a 20+ year old car that I don't want to invest overboard in. So far I have enjoyed working with this cable over steel. Folds VERY easily! You can bend these lines by hand, and unless you're making a very tight curve, you don't really need a bending tool (although I have one). I'm surprised how easy it is, and they don't kink that easily either (even when I made a really tight turn, they seem almost impossible to kink). I think you could bend a steel line much easier than this product. The ease of maintenance makes them astronomically easier to route under the car and in hard-to-reach places in the engine compartment. These lines are also 10x easier to flare. It's very easy to craft twin/bubble bells on solid steel piping. Other people here have mentioned that they are easy to "overheat" and I would partially agree. This takes some practice (especially with hand flare tools) and you don't want to run too much line through the flare tool or this can happen. Others here have also mentioned the wall size mismatch in them. I did notice a bit while flaring that bladder inflation was a little uneven at times, but that's hardly a complaint on my part. I can control this compared to the ease of use of steel pipe. And they didn't leak in my wheel cylinders or my tee in the back of the car, so they're expanding just fine. Today I did a test drive and the truck brakes great. No leaks, no problems. The real test for me will come with time as to whether these things will rust over the winter or survive. I will update my review in the future. Still, I applaud this product. If they survive the winter well I will use them for any future projects where I need tough lines, be it for steering, brakes or fuel lines. I just find it much easier to work with steel wire.
