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.
