Copper brake lines, what size?

  1. #1
    Re-plumbing my brakes with copper lines running inside the car, just wondered what size copper pipe I should be using?

    3/16ths or 1/4 inch pipe?

    To be used with this bias valve:

    tbh mate it aint worth posting. Best off going down to your local motor factors and asking them for a roll, it's only a few quid iirc
