Hello all,
96 1/2 ton Suburban...
One of my rear brake lines rusted out last night. its the Passenger side line that runs across the axle to the drum.
I would like to order up some Tube today but I don't know what size diameter it is. I am at work and don't have ant resources other than you all.
Does any one know the size?

(good thing for vice grips. I was able to crimp off the busted line so I could maintain pressure in the brakes, although I don't recommend that as a permanent fix.)

Thanks much.
