Rear Brake Line Help

[lkt1954]

I just got my rear cross over lines for my 69 C10 and I'm confused.
With the rear brake hoses on the calipers, the hard lines are way too long.
Are there different hoses and/or hard lines when you do a rear disc brake conversion?

Yes. The hard lines after the 'T' split are different on drum vs. disc brake equipped vehicles. You probably want to search for new rear 'disc brake' hardlines (or make your own).

What confuses me is I ordered these hard lines from inline tube and told them it was a rear disc brake conversion and yet I got the normal rear hard lines.
The right hoses almost would reach the tee.
Thanks

One thought to help crossed my mind.
Currently the calipers are mounted with the hose down.
On the front calipers the bleed valve faces up- rear currently facing down.
Is this part of the issue?

Yes. Bleeders should be @ the top.

All bleeders are on top.
Does anyone make a rear disc brake conversion lines?
What about shorter brake hoses?

I prefer not to have to make my own lines.

Thanks

I don't know of aftermarket disc brake rear hard lines being sold individually. I would guess they're part of a larger kit only but I've also never searched online specifically for them either. Whatever vehicle set-up the calipers & backing plates are sourced from would be where I started looking.

You would need to post up some more detailed images on what you're working with to determine if shorter hoses might help from an outsiders perspective.

Here are some more pictures with all lines laid in place.
The hard lines are run as if they were connecting to drum brakes.

The flex hose on the right is 3" short of the tee block and the left flex hose is about 24" short of the tee.

I see a few options:
1) Use braided flex hose in place of the hard lines.
2) Find pre made shorter lines and bend to fit.
3) Shorten the lines I currently have and hope I get good flares.

Any other thoughts??

I shortened a couple lines on my truck. It wasn't too hard to get a good flare, even with using the tools rented from your local parts store

Easiest option I see is shortening the existing lines to terminate into a tab on the rear end housing @ each side (similar to how the fronts are terminated & done).

As far as flaring tubing, doing a flare on a straight length of mild steel brake/fuel tubing is fairly strait-forward.
If you don't want to go that route, ordering in flex lines the required length would be the next option.

If it were me, I would ditch those 2 foot long hoses and get some short SS or even rubber hoses. Run your steel lines close to the wheel and put your 3 way block wherever is convenient. Having those rubber lines dangle all over the place looks like an accident waiting to happen.
