Default Rear R brake Calipers in 240 - Hard Lines

Hi all,

For those that have made this rear conversion before, is there an off-the-shelf solution available to get the rear brakes to work?

Thanks

No thanks. I hate building brake lines. It also does not resolve the problem that there would need to be a female to female adapter anyway

I think I found what I need:

https://www.summitracing.com/parts/rnb-785-439/

That and a metric bubble flare assembly should do it, unless somebody else has a better suggestion.

Also considered a compression fitting to extend the hard line but this seems like the type of application where that solution may not be the best...

Buy 3/16" hardline with 10mm bubble flare on both ends from your local autoparts store?

The bubble coupler you posted will allow you to go full TB. if you want find a single line that'll work.

Or you can come by the shop and we can do it with AN fittings and hardlines....

I got this, not sure why 77volvo245 didn't post that for ya lol, is that what you need? Maybe its because you said hard lines, This is better and easier.

The only other thing I did in the rear is remove those pressure reducing valves and install a $20 set of stainless lines (from FCP, it is the front brake line set) .

What makes this better or easier? no reason for a flexible line at the caliper for solid axle apps.

I not only find it to be child's play, I enjoy doing steel or copper/nickel lines well. There are female flare nuts. BTW.
I didn't look at all the particulars of your swap, I'm only here for the reported post.

That is correct. If you do it on the flat side instead of the flare side of the holding fixture it works very nicely.

One for those who want to get their hose on:

In my case, it was better because the brake line was about 40 years old. It was easier to bolt on new flexible lines than bend those old ones around.

I did buy a bubble flare tool and used to redo a couple cruddy front lines. It's pretty easy if you buy a good one, my second flare was perfect and the rest were also.

True or have a new hardline made, the stock lines aren't long enough. Solid axles 740s have flex (soft) lines.

9 series as well.... all the 940s with live axles and the early 960s too. Perhaps the same rear binder kit will bolt up to the 1041 rear axle flanges as STS designed for the 1030/31 rears?

A 1041 is exactly the same aside from the locker carrier.
