Technical Rear brake flex hose rotates

Not running a vent will make it hard on the seals to keep the oil in and I would make the hose lay flatter high points in brake systems make it harder to bleed air out of the system.

 

I will definitely be running a vent on the axle; just not one of those vent bolts for the hose to mount to.

I’ll keep that in mind when finding the best position for the hose - high spots are not desirable.

 

Not sure of final, but sounded real impressive

 

I'd go elsewhere and buy the correct parts with the hex design. Those parts look like something that China has p***ed off on us.

This may not be possible for the OP to do, but.....
The longest life of a hose will be achieved by making sure the hose flexes in its length, NOT at the crimped ends. Picture a "U" shape, with the ends firmly attached and the ends moving up and down relative to each other. This places all flexural movement in the body of the hose. Flexing near the ends will stress the braiding in that localized area and lead to early failure.

 

"Stressed simply" = 'simply stressed'.

 

These hoses are there to flex, not twist. If you limit the twist at the bracket the way you have it, the hose will have to twist and won't last long. You need to configure the bracket so the hose only needs to flex.

If you put a 90 turn in the line so the hose was parallel to the housing there would be little or no twisting.

 

So I’ve mocked up another. No hose rotation, but now the hose is pretty high (bleeding issues ahead??) and I wonder if it will hit the underside of the body - that can’t desirable, either. Also, is this too close to the shock? Seems like plenty of space to me. And the hard line from the hose is just a practice piece. Real deal will be longer.

 

Go to a local yard sale and find an old ring spanner [wrench] the same size.
Cut off the handle and grind it smoove and weld it on.

I did similar with a "chinesium" deep socket , I cut into 4 sections and welded them onto tabs. [for a hydraulic braked trailer]

 

^^^^^^x2. I have had to put a twist in my front brake lines to keep them from hitting things when the wheels are turned. 49 yrs and at least 49,000 miles and and holding up fine. Twelve point frame brackets.

 

I was thinking the 90 would point across the vehicle not up.

 

If the exhaust is going over the rear axle, I would mock that up before finalizing the brake hose location.

 

I didn't have exhaust over the axle, so I went this route.

I'm running into the same placement issue (not the rotational problem)
The guys at Pete & Jakes say to use Wagner F106330.

 

I dont like that style of fixing. Its designed for quick ***embly by the factory. Use aeroquip stainless hoses or use a bulk head connector on the frame.

Another option is to make a p-clip style clamp to locate that end.

 

My set up on my PU is pretty much as the OP showed us in the his first post. I welded the tab on the frame rail and used a hose I had made up over at Oil Filter Service in Portland with a ford style tee and a vented bolt.

I drilled and tapped the axle for the vent since the original vent hole was inconveniently positioned between the u bolts (as you can kinda see below). I sealed it with a hex plug and RTV.

The new vent location made running the hard lines easier as there are a few obstacles with my sway bar mounted above the axle and the parallel leafs. In the pic the vent is covered with a vacuum cap to protect it from debris as this was early on in the build. I need to remember to remove that damn thing!

I used a spacer below the tee so the line could p*** above those u bolts.

One thing left unmentioned thus far is once the SS hard lines are all attached and secured there is no movement on that fitting or the line on the frame.

 

I like my solution to the problem much better than any of the responses so far.

I have never been a fan of brake lines mounted to the rear end.

So when I built my RPU I didn’t want any brake lines mounted on my new Quick change.

I mounted and ran my brake lines to both sides of the frame ending the hard lines on each side just above the brake, that way I could use a rubber hose on each side dropping into the brake.

Clean and effective and easy to bleed.
