Drove my '50 2R5 the three miles into town today; went to the grocery
store. Unfortunately, I had a little problem.

When trying to back out of the parking stall, I only moved about 5 feet
before I killed it. I realized quickly that the brakes were locked up.
The parking brake was disengaged, but offered no resistance when
engaging it. The brake pedal virtually no travel, and was extremely
stiff. I took a peek at the master cylinder; everything looked normal.
Lacking a better idea, I opened the little petcock on the rear passenger
side, and about a 1-2 teaspoons of fluid oozed out. This apparently
solved the problem; the brakes seemed to function normally as I drove
around the parking lot a few times.

Obviously, any problem when the brake system is cause for concern. I've
looked through the shop manual, the NG, and the SDC forum, but I've
found no leads.

Ideas?

Sounds like you have your master cylinder rod adjusted too tight. Back it
off a bit and try it again.

Thanks for the tip; I'll give it a shot.

Man, I love this NG...

Your Parking brake also might be stuck on, and cause the drums to overheat,
expanding the fluid. By bleeding, or dumping fluid everything might feel
right, but since yout E brake handle offered no effort to pull it, that
indicates that the cable might hav snapped when the E brake locked up.

Check it out......thats how the Hawk went on fire........... no effort to
pull handle, drove it for quite a while, and whamo, stiff brake pedal and
then fire.

Actually, that's one of the first things I checked; I was able to
operate the parking brakes at the wheels themselves, and the cable was
perfectly sound.

It has yet to happen again; I suspect Jeff was right about the master
cylinder rod. But thanks for the suggestion. :)

Sucks about the fire though. Damn. :(

One remote possibility might be a bad hose with a peice making it to
act like a check valve. It's thought of as more of a front wheel
problem, but same might apply back there.

It is about .010/.015 " in diameter.If that hole gets clogged it will produce the symptoms you describe. I have seen these holes that look like someone started to drill a hole by using a center drill and then did not finish, but there is a very small hole in there. I have used a small piece of wire to clean mine out. I hope this helps, Doug
