Size of Stock Brake Lines?

[xd2200]

A little difficult to discern under the armor (spring) protection but looks likes like 5/16" - correct?

I just switched over to a corvette style dual m/c and had to buy 3/8 (or was it 3/16th) to 1/4in adapter lines to run from the m/c to the stock lines.

I hope that helps.

They are 1/4 inch steel brake lines.
