When I started it (after a few cranks and a boost from my own Subaru) the owner informed me that he doesn't have it (a street-parked car) registered/insured so I would have to use my own insurance to take it to a nearby mechanic for inspection. He also informed me that I would be driving as a result, which is good because he didn't have a license.
We wisely decided against the car and that was before I even attempted to move it a few inches. Who knows what mysteries the braking system contained?
Technically if the breaking system has had motor oil in it any any point and time your supposed to replace the whole system including the lines.
