Hello folks. Just picked up a 2002 Stang for my 18 year old daughter for her 1st car (she has been driving my 2004 Ford Excursion the last 2 years lol). We bought it from the original owner who had it non-opted and sitting for about a year. While going though the brake system I found a small fluid leak on the drivers side rear brake line where the bolt connects the brake line to the caliper. My question is will getting new crush washers fix this issue or should I replace the brake lines all together? I can only assume they are the originals even the original owner did upgrade the rotors to cross drilled/slotted and performance pads. Thanks.
