Sounds like an ideal time to upgrade to these:

As far as what to be aware of (generally speaking because I haven't done the VX ... yet), other things are likely to break when removing rusty brake lines. When I was putting SS brakelines on an old Samurai, the mounting bracket broke and one of the hard lines. The bracket wasn't bad because I was able to 'redneck engineer' a fix (foam pad & zip ties). The hard line was more interesting but I was able to salvage the old line by using a plummer's flaring tool to make a new connection.

I can't remember where the ABS fuse is. Someone else will have to chime in on that.
