Routing of front brake lines

[SeabeckRedneck]

A question for those of you smarter than I, (insert joke here), I'm replacing the factory brake lines in my 70 B body along with changing the M/C and calipers to a Wilwood disc set up.
I've decided to cut, flare, cut again, install the fittings, flare and bend new brake lines. Mainly just for the fun of it. So now for the question, the factory lines for the front go under the frame rail and while I can bend the new lines to match, would it be better to go over the frame to minimize risk of damage? Not that I've seen any brake lines that have been damaged from going under, but it would also be a little less bending if I go over the frame instead of wrapping under and up.
Any thoughts?

Thanks!

Other than not being factory correct and don’t think it would be a problem.

Pending which side you're talking about, the factory did them both ways !

Bend them the way it was born with.

Agree with all the above, over or under really doesn't matter although I prefer over the frame for reasons you stated above. Makes more sense. It also depends on your patience with making the bends. That also depends on if you're using stainless or copper-nickel. Stainless is a bitch to bend and tricky to flare but it's forever. Either way use stainless rock guard and you'll be fine.

There a reason every component that comes in contact with reactor coolant is made from 304 stainless. If you do go stainless get 304 or 316. The other stuff will rust. 316 is the best. 316 isn’t used in nuclear only because it wasn’t available when the plants were built in the 60s and 70s. 304 was the best at the time.

Sounds like you may have worn a TLD.

Yeah, I'm running copper-nickel... a little more forgiving.

After making the first flare and bend I use small nylon tie wraps to wrap the old brake line too the new lines and follow all the bends while keeping up with the zip ties.

Ya think? 40 years, just retired. How about you?

I also remove the first fitting just after the flare so you can lay the new line flat, just remember to leave yourself extra line to form your flare.

Congrats! 35 years here and just retired in January. I was on subs in the Navy and have been working on subs in the reactor compartment. So you know I glow in the dark!

That's a great idea! Thanks

don't flare the tube without the fitting!

You actually have to at least once by law... Murphy's law!

I did 5 years on the SSBN 608 and SSBN 726. Then got out and worked for Puget Sound Naval Shipyard and Naval Submarine Base Bangor working on all the Tridents and Seawolf class boats on the nuc systems for NRMD as a project manager.

F@cking swabbies.

The correct term would be bubbleheads for submariner’s.
