Yellow lights no longer make your butt pucker, right? Lol

My right rear drum is locking up. Pretty dangerous, really.

New brake booster/prop valve (disc/drum), master cyl. New pads/rotors up front and new shoes with good drums in the back.
Multi-bleedings with no air in the system that I can see in the bleeder jar.

It's the pass rear brake that's locking up, and locked up first *before* I recently changed out a leaking wheel cyl) may be out
of adjustment ????? I don't know.

I *do* know that I've never been able to get a good enough adjustment on the parking brake to make it work properly.

Gotta play with this one. Possibly I have a bad P-valve? I'm not too happy with the overall brake performance compared to my '72.
So maybe it's a crappy booster/m/c/prop valve set up all together.

Or maybe I just need to play with the adjustment on the pass rear drum???

Not sure why anyone would waste one penny on a used windshield when new ones are $211.00 installed , this includes a brandy new crappy Chinese made rubber grommet if you go to Safelite Glass Co. ~ they're on the Internet , just google " cheap windshields " and you'll get lots of professional glass shops that'll do it cheaply , while you wait .

New glass is one of those amazingly good dollar value things , once you look through a crystal clear glass instead of the old pitted ,scratched one , you'll be sold for life .

Bill there are a couple of things that will make the drum brakes lockup. Rear end oil on the shoes from a leaking seal will make the shoes grabby and lock the wheel when stopping. And it's possible one of the cups in the wheel cylinder is stuck holding pressure on the shoes. I doubt the p valve is the culprit as both the rear wheels are on the same line from the front so if one side locked the other side should too. Most likely. Check the brake shoe adjustments? I hate to ask but are you sure you have one long shoe and one short shoe on each side? Long shoe to the rear on both sides?

Good brake advice.

Boog and Tom:

One thing I know for sure is that when something isn't working properly, there's something I DON'T KNOW, THOUGHT I
KNEW AND DIDN'T, or DIDN'T DO CORRECTLY...Hahahahaha!!!

I rebuilt the brakes a year ago before I was done with the build. Then, 400 miles with slight pulling to the right. Nothing as
terrible as it is now. Then the right rear wheel cyl started puking fluid.

As far as I can remember, I put it all together correctly.

But with your info and Tom's, I'm headed down for a new set of shoes, I'll re-check for proper shoe placement and adjustment...
...and if it's correct on the passenger side, and the new ones still pull (should say, "lock up" waaay early) without ever having been
"wet", then I'll pull the driver's side to make sure that both sides have the shoes long-to-the-rear.

Two sure things:

1) Something's not right;
2) It's REALLY dangerous...You should'a seen the smoke I laid down sliding toward a "surprise" yellow-to-red light from 65 out on
our rural highway.

Oh, and the third thing:

3) I really appreciate the input. Drum brakes are not my long suit. Keeping them for now. If I can get 'em to work properly, I'm
keeping them forever.
