I have a '72 Scamp with no brakes at all (the e-brake slightly works) I want to drive this thing 15 miles to my garage so I can get it in my garage to fully work on it. Right now I have absolutely no idea how this braking system works. If I were able to just get the front brakes to work will that be good enough to get it home or does this system need all 4 to work? It's a manual brake system with drums on all corners. The plan is to do the front wheel cylinder, rubber lines, shoes, and springs.
