Howdy!
Im going to be running all new brake lines in my truck during my winter break and i was wanting to know what size of tubing i should go with. I will have disc in the front and drums in the back and im thinking about going with stainless lines and fittings. I know with stock there were two different sizes used one smaller and the other larger. Should i stick with this same set up or could i go with the larger size tubing all around?

Hy gumbi, I think your choice of tubing size will be influenced by the port size in your combination valve, I know most of the valves I have seen used two different sizes of line, and quite often the individual front brakes have their own line right from the combination valve. Lest We Forget.

If your going with late model brake stuff you could get by with 3/16". If your going with aftdrmarket stuff you should use what is suggeted by the manufacturer.

I'd think twice about the stainless line. I did one truck with it, and while it worked fine and turned out well.. it was a real pain and huge aggravation to flare and bend just right, even with the best tools I could find, and I'm pretty good at flaring, fitting, and bending lines.

I now use copper nickel brake line

It's so much more friendly to work with and 3/16" was about the same price or a little less than stainless last time I checked. Although even if stainless were about free I doubt I ever use it for brake lines again.
