Why the loop in Brake Lines

I am just installing a new Booster and master cylinder and making a bracket to house the line Loc and adjustable proportioning valve, and was hoping to tidy up the hard lines.
Why is there always a loop in the hard line after the valve, can you do with out it, it would look a lot tidier if I didnt need to loop it

Re: Why the loop in Brake Lines

It helps against work hardening I believe. Liquid lines that sit dangling without any brace will, overtime, become brittle and fail.

Re: Why the loop in Brake Lines

Somewhere I read it was simply an aid for the assembly line. Gave them some flexibility when marrying the subframe to the body. Don't quote me on that. I hope that's the case - I made my own brake lines and didn't include any loops.

Re: Why the loop in Brake Lines

I ordered new stainless steal lines from RightSuff and they did not have the loop in them. They may look better, but they were a pain in the butt during install as they were a bit too long. I had to creatively bend them so they would shorten up. If they had the loop in them, the install would have been a breeze. I guess better too long than too short as I am not sure what I would have done.

Re: Why the loop in Brake Lines

I would expect the loops are there for thermal expansion/contraction reasons as well. Pipe curves are a lot more flexible than straight lines. If it were straight, it would probably crack overtime due to fatigue stress.

Re: Why the loop in Brake Lines

Yep, as JohnZ says (our god) it was for ease of assembly. Little time had to be spent lining up fittings. Also, us kids used to look at the springs wrapped around the steel lines and talk smack about the springs being there for cooling when high performance racing. Yeah, right. The springs are there to keep the lines from kinking when tugged and bent to fit quickly on the production line. Kids,,,, Don't miss it.

Re: Why the loop in Brake Lines

OK, now you guys got me worried. If the loops are there to support flex (which makes total sense to me), why do places like RightStuff sell non coiled lines? Am I setting myself up for future issues by running lines without coils?

Read the thread I linked, esp the post by JohnZ. He was there when these things were built. Put your mind at ease.
