Rear Disc Brake Plumbing

[AKguy]

Okay, 1980 K30. I have the new rear disc brakes mounted on the 14 bolt full floater and am ready to plumb. I used the same calipers as on the front and they have M10-1.5 threads where the banjo bolts normally go. I would like to run hard lines all the way to each caliper. As an option, I could use flexible lines if I had an idea which model vehicle I would need them from that would reach the top center of the differential, then install a three way block. Anyone have experience with adapters for the hard lines or specific flexible line that were used to accomplish this task? Thank you in advance.

Maybe this, add a copper washer if needed:

Or maybe this, with a 1/8 male pipe to inverted seat?

If the calipers slide in & out, won't you need flex lines?

You’ll need flex or rubber the last foot or so. Last I looked, ORD had sourced a full flex kit for our trucks.

Look at offroaddesign.com

I bent and flared my own with 12” or 14” flex at the end, but the ORD kit looks like a simpler way to go.
