Title: brake lines
Post by: Buddy on September 04, 2010, 07:29:40 am

I am just about to install new brake lines from my master cylinder down to my junction box. I don't have Any of the old lines and I think they my be two different sizes. Does anybody know if this is correct.

What year is the truck? The flare nuts could be standard or metric.
Pretty sure the brake lines for the front are 5/16", and rear are 1/4".
