After recently having the drums machined, shoes replaced, and brakes bled and adjusted..............all was rolling/stopping well. Till tonight.

Decided to take it for a stroll (bad idea). Thought I could take it on the back roads to get in some driving time. Well, didn't think about the time and everyone trying to get home after work. So as you can imagine I had to do a lot of braking, stop and go, from light to light. Engine was getting hot, I could smell it from time to time. Once I got going, it was fine again, and smell was gone.

Last weekend, the brakes were fine and stopped. There were no signs of pulling one side to another when applying the brakes. Tonight, I started off fine. About half way through the ride it started pulling badly to the right front side. I started heading back for home, but I was still a good ways away. But pointless story short, the brakes pulled really hard to the right. Got it in to the garage and put my hand on each hubcap to see if there was any heat. I could feel luke warm heat on all three wheels (all were similar), except the right front. That was hot AF! I pulled off the hub cap with a screw driver, and the drum was even hotter. obviously.

I'm assuming this means that the brakes need adjusted on that side, After I drove it last weekend after doing the brake job, I got home and adjusted the brakes so that all were identical. So I figured I was done. Guess not

Is it safe to assume this right front brake just needs to be adjusted? Any reason to think the bearings are bad? Or axle nut may be too tight?

You'll need to pull both front drums and take a look. Could be bad adjustment, broken spring, bad flexible brake line at front right, bearings, anything almost.

If you install the adjuster incorrectly, this will cause binding, dragging, & overheating.

I'll definitely taking the front apart this weekend.

When you say "adjuster", you are referring to the star mechanism, right?
How the hell do you install that incorrectly? It only goes in one way, no?

Maybe a brake cylinder hanging up when it gets hot? Take it out, apart, and grease the internals of it with brake grease and see how it does.

The adjusters have angled slots (some years) and you might be able to inatall them wrong, but I'm not sure you could install the drum if you made that mistake.

If all looks good then I would suspect a sticking wheel cylinder or failing flex hose to that front wheel (they can fail by acting like a one way valve that won't let fluid return.)

I did not replace the front wheel cylinders or front brake lines. All was dry so I left alone.

I'll check the brakes, then go from there. I'll check everything Saturday

One way to determine if it’s a brake line is to jack the car up and see if the wheel spins after taking it for a drive. If it’s hard to spin, leave it and come back in an hour. See if it now spins. If it does, you most likely have a bad line. What happens is the lines collapse internally. The MCpushes the fluid through and the shoes engage. The line collapses and keeps the pressure from relieving. Letting it sit, it slowly leaks back and releives the pressure, disengaging the shoes. Been there.

Front spindle nuts could also be too tight, but shouldn’t cause pulling.

Or open the bleed valve there and see if fluid squirts out, and if the drum then turns.

Here's the adjuster.
One side of the slot is deeper.

If it's installed upside down, the brakes will do strange crap.

Check the bleed down as suggested above.

angled adjuster screws depends on the year. 65 was the start from the factory.

Oh wow, I didn't realize the slots were different between the two. That makes me wonder if that is the issue. hell, I removed all the stars and cleaned them up. It may be correct, as I took them off and cleaned them so they'd go back on the same side they came off. But I have a track record (bearings) of mixing parts up. But I'll compare the drivers side to the passenger side and see if I see anything different.

well, I did just bleed the brakes last weekend, so I know fluid came out and all was functional. I couldn't imagine it being completely closed after one weekend....but what do I know.

That's the thing, it will bleed. What you want to see is if it releases pressure on the shoes. The lines will collapse after the fluid is pushed through causing the shoes to keep pressure on the drum. Rather than driving it, you could also jack up the one wheel and check if the wheel turns freely. If it does, pump the brakes and then check to see if it is still turning. If its not and frees up after opening the bleed valve, you most likely have a bad line. The pressure from the MC opens it up to push the fluid through, but it isn't under the same pressure returning back through the line so it stays collapsed keeping pressure on the shoe.

I will say though that your adjusters look to be possibly uneven. Shouldn't result in the symptoms youre having but will make the shoes wear unevenly.

Just putting it out there. You might also want to make sure that your new shoes match the profile of the old ones where they seat into the adjuster, the new shoes might have been made to work with the newer style adjusters.

The first time I ran into this situation was on a '60 that another shop had done the brake job & I had to disassemble everything to find out where the fault was.
