Re: Barrel (Inverted Flare)nuts for hard brake lines
Hey everyone hope you're all doing well in these times right now. I went to install new hard brake lines on a new rearend for my 66 Chevelle this morning. I bought new 3/16" brake lines and when I went to thread the the new line to the caliper the barrel fitting on the new brake line is a bigger size than the original 1/8"-27npt that the car has. Does anyone know where you can buy just the barrel/ tube nuts anywhere? I looked on Summit and Jegs with no luck. I'm putting a Strange S60 rearend with Wilwood disc brakes. Any help would be greatly appreciated thanks and be safe 👍🇺🇸👍
It would help to know which Wilwood disc brakes are installed on your S60. Many of the better Wilwood kits have 1/8"-27 NPT threads in the calipers which you have to install an adapter fitting (1/8"-27 NPT male to -3AN male for example) in the caliper, a short -03AN female to -03AN female flexible hose and a Brake Adapter Fitting SAE female 3/8"x 24 to -03AN male connected to your male 38"-24 3/16" brake line fitting. Here is a photo of what I did on a 1965 12-bolt Chevelle rear back in 2004 (removed in 2017) as an example. You can run the hard lines directly to the calipers provided they are fixed (rigid mounted) and not the floating ones but the installation I have done with the flex lines just makes the installation a bit easier to work the lines around the rear shocks. Never had any fluid leaks on this rear setup.
