Stress relief coils in brake lines?
How many of you are bending coils into your brake lines when doing a new setup? I think I got my flaring down, and now starting to run lines. Have gone through about 6' so far that I scrapped. Trying to get my bending down with the tool wherein I don't crimp the line and do a smooth 90*. Using copper.
Was fairly easy to do a stress coil around a can of glass cleaner, but wondered if it's worth the time? |

I do them on my trucks.

Never add the coils.

I prefer to clean look of well run lines. I see no need for the coils.
If it was a line that was constantly be connected and disconnected I would understand the need. To me it's like adding coils at the wheel cylinders or any other connection for that point. |

The cab is mounted on the body mounts with the master cylinder hard mounted to the cab; the brake lines are hard mounted to the chassis. The cab will move between a quarter and a half inch due to jounce or twist. Something's gotta give. No relative motion between the wheel cylinders and the axle tube, which is why the brake lines can be hard mounted to the tubes (the suspension travel is taken up in the center with the rubber hose).

i put them in at the master cylinder. there can be flex in the body to frame which is why they are their. at the rear they are attached to the differential which has no flex.
done correctly they look great AND professional. using copper is a big no-no unless you are referring to the 90-10 copper/nickel |

(99-06 silverados excluded). If there's not enough flex in a steel line that drops from the M/C to the frame to keep the steel line from severing on a truck that I drive,... then I will add the coils to my next project or daily driver. |
Re: Stress relief coils in brake lines?
nothing to do with severing the line

It also stands to reason that the factory did it for a good reason. If there was ever a chance to shortcut something and save 1 cent, they did it. They also had to design for the WORST case condition for 100K miles, which these trucks are probably not going to see again. |

See any issues using that? |

We also have to accommodate build variation from truck to truck across 1.5 million vehicles, which the enthusiast would not have to comprehend when doing 1 vehicle. K |

Exactly and the only thing that I would like to add that is every time you hit the brakes, the booster and master will move a bit as well. I am used to unibody cars so I always put coils right below the master |
Re: Stress relief coils in brake lines?
If you don't want to run coils, then don't run coils. But don't try to justify what you are doing by suggesting the coils don't serve a purpose.

Re: Stress relief coils in brake lines?
Interesting spectrum of answers here. Given that I haven't heard any negatives in regards to running them, other than perhaps aesthetics, I'll opt to include them in my setup.
