Is it possible for the ABS system to cause the brakes to be completely non-functional? I'm looking at an SLC- the owner stated that it needs a new ABS unit, but deems the car undriveable because the brakes do not work... Anybody have any thoughts on this? I'm a mkII guy and have absolutely no experience with ABS. I'll most likely swap it out for a different setup if I get the car, but for now I would just need to make it driveable.
