Brakes going soft after raising car?

It's a pain, and brake fluid and paint don't get along well. It's possible that your rebuilt master cyl is defective. That happened to me last year, caught it when bleeding the master, metal debris in fluid. Start over with rebleeding the master, then the lines. If your problem persists keep looking, a leaky master may not show immediately, but you will not like what the brake fluid does to your firewall! Just looking at all connections is sometimes not enough, run your finger over it, make sure they are all dry.
You may need to replace the emergency brake cable if it is sticky and will not free up with oiling the entire casing front to rear. Your choice, rust blaster first, then oil.
Don't know if they are still available, but one of these is nice for rear ballpark adj.
Good Luck, nice Dart.
