Offhand, does anyone know the stock fitting size for our rear brakes? It's a female something or other. I imagine anyone who sells the SS rear blocks like RE would know. But I thought I'd see if anyone on here already knew. Jon, maybe?

A little more info. Do you mean the hard brake lines going to the WC and hose. Those would be for 3/16" brake line, the tube nuts(flare nuts) would take a 1/2" flare wrench IIRC. These fittings are male and come long or short.
PS- they are double flare

Yeah, it's a flare nut, and I know the size the nut takes. But I am after the actual fitting size. Would be something like 1/8-27 NPT. Male for the flare nut, female for the cylinder and junction block.

I'm inclined to think it would be 5/16" SAE or 3/8" SAE double-flare, but no-one has reported back to me yet. Measure the OD of the threaded part of the nut, and use that as a quick measurement to select a replacement (if you're bending your own lines from straight.)

Brake lines are usually double-walled tho, so don't use just any old tubing and expect it to work...

3/8 x 24 fittings at both ends of the rear axle hard lines. And double flared 3/16 line as said already.

Thanks, shiat always has to be difficult. My Wilwood caliper has a 1/8-27 NPT fitting after my tube adapter, was 3/8-24 I.F. before. So I guess I'll have that at the caliper end and 3/8-24 SAE? at the block. Going with braided stainless and crimp on fittings Jon.

I s'pose I could lose the adapter and go 3/8-24 Inverted at the caliper. Keeps the thread the same, though the flare is still off.

There are adapters for everything, well sort of.

I didnt realize there were pipe thead fittings in any braking system, a mixture of IF and AN fittings is enough of a headache to adapt.

As always, the fewest connections is the best.

Most aftermarket brake accessories are pipe thread. I have I think 6 pipe thread to IF adapters on my XJ. Both ends of 2 line locks and an adjustable prop valve.
