What's better?
Making vertical loops or horizontal loops in the brake lines from the master cylinder?

I'd think horizontal so there isn't multiple high spots for air to get stuck.....

Start high (next to master), then circle down horizontally.

Plus, I don't think I've ever seen any vertical ones either.

You want vertical loops in the lines from the master cylinder down to the combination valve or splitter, just like the factory put. They're there for a reason: to allow the lines to flex without work-hardening and becoming brittle.

That makes sense.
But I just saw some vertical ones on a 1968 Valiant.
But maybe they weren't stock.

Or maybe it was stock?

Yup, the vertical loop-de-loops you saw were stock.

Just so I'm sure we all using the same definitions:

I consider this to be a horizontal loop:

Loop is horizontal, flow direction is vertical.


Vertical loops are turned 90 degrees so

Loop is vertical, flow direction is horizontal.

I would agree with that statement, BUT after seeing SSD's post maybe we need to see if he speaks again... Maybe your and my definitions are different than his... I dont think I have seen any 'vertical' loops in brake lines either, if our thoughts are the same.

This is what I would call vertical loops.
They were clipped together with a metal S clip. It looked like the factory did it.

No. There are plenty high spots all the way along a brake line. Unless you have so much moisture in very old brake fluid as to cause a steam bubble in a high spot because of local heat, a normal brake bleed job will clear away all the air bubbles. If air in a brake line remains a problem, leave the bleeding to a brake pro. Always bench bleed the master cylinder.

Everyone's on the same page: we all mean the same thing when we say "horizontal" and "vertical", and neither type of loop should cause problems with air bubbles. Seeing emsvitil's pic I am guessing(!) the horizontal loops would provide enough line flex if there were enough coils to the loop-de-loop. Guess I should look under the hood of my '91 Spirit and see what they put in that.

Vertical loops in the '91 Spirit.

The coils should lie in the vertical plane. If they are in the horizontal plane, they will continually flex and vibrate as the car hits bumps in the road...possibly leading to fatigue fractures.
