The Stovebolt Site Forums The Shop Area Driveline Installing brake lines

I have 1950 3100 which currently only has the cab on the chassis no other sheet metal or engine (the engine is ready though). I am ready to run new brake lines for the dual circuit master cylinder.
Is it better to run the lines before the engine is installed or after? This is my first "Restoration" project and can see positives and negatives of each.

Easier before you add radiator and such. I am doing same thing with engine and radiator in place. The less you have to work around, the easier it is

easier to work around with nothing else in the way, although you want to make sure you are staying away from where you will eventually run your exhaust.

Stock truck? Follow the stock locations. Generally, easier to move around with out stuff in the way. Modified truck? Everything matters. Heat is the enemy, so is possible contact with any possible movement(engine vibration, exhaust pipe movement and suspension travel). I know it sounds dumb, but some times people forget. You can heat shield, but better routing is safer. Don't forget fuel lines while you are under there.

I'm only upgrading the brakes to a dual circuit system. Everything else is going to remain stock.
