Brake line size??

I am getting ready to run new brake lines on my 50 Chevy. Should I use 3/16" or 1/4" brake lines. The particulars (if it matters) 94'S-10 rear drum, 54' front drum, 67-76 non-power Vette master cylinder.


Thanks,
Todd

 

I have a similar setup and used 3/16.. most of my cars are plumbed with 3/16 lines...EVILT

 

1/4 inch from front back to rear brake hose, and 3/16 from hose out to each cylinder.

 

when building from scratch, i use nothing but 3/16. no need to use 1/4.

 

I suggest Heathen posted good. You don't really need 1/4 for a rear drum setup, BUT....if you at some later date change over to a rear disc setup, you might need the volume that a 1/4 line would flow. Run the 1/4 to the rear, but use 3/16 everywhere else. It won't make any difference in brake performance, and the expense is negligible.

Ive got disks all around on my 32 coupe and 3/16 lines .. they work fine!

I used 3/16. Vette master, disc front, stock drums in rear and an adjustable valve to the back. I am curious why you chose a disc master for a 4 wheel drum setup over a chevelle/mustang 1" drum master?

 

vette m/c, 2 lb residual valve in the front, 10 lb in the rear. 3/16 line to the rear, 1/4 to the front. stock MII calipers & 10in drums w/7/8 wheel cyl. Truck squats & stops. Period. No nose dive, no worries.
