When I tried these coils on my automotive brake system, I was pleasantly surprised with the results. The coils were easy to install and helped improve the overall performance of my brakes. The coils remained sturdy and durable, even during rough conditions. On the downside, they were a bit more expensive than I anticipated.
I used this to replace rusty rear brake lines on my GM truck. Simply flared and bent with a small tube bender or by hand. These are not stainless steel and if left untreated they will rust. I will coat it with anti-corrosion paint and check it out in a year. I used 6ft of pipe and 4 flare nuts for a total of $6 and now I have new rear end brake lines. I'm using the rest of the reel to replace some of the brake lines on my Acura TL.
