Brake line size?

[1moretoy]

Hey guys getting ready to plumb my brakes and need to choose a line size. Brakes are 6 piston front 4 piston rear with a 1" wilwood manual master cylinder. Thanks

I used 1/4 inch front and rear. Number of pistons doesn't change line size but does affect the amount of fluid you need to add as the pads wear.

I use 3/16". One each for front disks and one shared for rear drums.

For a 6 piston caliper disk, recommend ask the mfgr. Factory used 1/4 all the way around for drums pre-71, and then 3/16(front) and 1/4 rear for 71+ disk/drum pkgs. If there's not a mfgr recommendation, I'd go with 3/16" all the way around for a 4-wheel disk setup.
