    Great products

    I'm a Master Tech and use this brake line at work. So easy to bend and flare plus it is super corrosion resistant. Now I am going to plumb my brother's 1961 Chevrolet C20 pickup with your 3/16" and 1/4" lines. We're swapping out the torsion bar front end with a coil spring unit and will have to install all new lines. Your products will do the trick. Thanks for the quality components!
