Brake Line Size And Mounting

[Project Bike Truck]

I am trying to get the rear end finished in the next 10 years or so on my project.

My questions are what size brake lines should I run?

And How should I mount it?



I plan on hard line and a flex at each end. i come from an off road background and we used to weld these rad little stand offs on the rear end (cant find them anywhere). I have notice guys drilling and tapping clamps to the rear end (does this leak?). looking for some thoughts and input.

thanks
