Thanks Guys. I couldn't find a definitive answer on the web. I appreciate it.

I agree with Mark.  I suppose you could find multiple sizes available at parts stores, but 3/16" is what I have.  It matches what I took off.

In my Parts Manual, GROUP 24-07 - Brake Tubes - Hydraulic, 

it indicates sizes for the brake line clips that secure the tubes but not specifically the size of the tubes (brake lines).  3/16" for clips to secure to the frame but 1/4" and 5/16" clips for the axles.  Keep in mind that those brake tubes have protective welting on them making their diameter larger.

Stock 3/16" line will work just fine. I have them on my 2A with 11" brakes and it will put the passenger through the windshield if not wearing a seatbelt.

I am working on a 54' 3B that has been upgraded to the 11 inch drum brakes. Do the original brake lines need to be bigger or will the stock factory lines with original master cylinder work?
