jdfred,
I have had brake lines fail internally in cars. Once had the front brake of an oldsmoblile lock on during a trip away from home. Turned out the inner lining of the flexible brake line was failing. A flap of the line material would alow the fluid through to the caliper but when the brake was released the flap would extend and prevent the fluid from returning, thus the lock. The outer surface of the line was in great shape. Given this I believe it can't hurt to replace the line. Worst case is you end up with a new line on an older bike (win win).
