Got around to (finally) replacing my master cylinder yesterday, which went smoothly and quickly... why I waited so long I've no idea. Probably spent more on brake fluid in the last few months than I did on the new master.

Anyhows, I crawl under the car after I'm done to take a gander at the bleeding situation, and what do I notice but a drip of brake fluid on the bottom of one of the flexible brake lines. Lesson to be learned: diagnose the true source of the problem before buying parts based on assumption. Good news is that now I've got a new master cylinder...which surely would need replaced soon anyhow after 34+ years. And it means my brake booster isn't as full of fluid as I was figgerin' it to be.

Now of course, a flexible brake line ain't the sorta thing that I'd usually replace with a used part, but its all I've got, and the used one I have is not original, so it's been replaced at some point.

Question is though... my '70 which is experiencing this problem has two flex lines going from the biasing cylinders to the junction on the rear end. The spare I have came off a '71, and it is solo... never were two lines on that one. Why/how I didn't ever notice that when I swapped rear ends I don't know.

Anyone know if the solo line from the '71 is the same part as the two that are under my '70 wagon?

Thanks,
Matt
