Default Rear Drum Brake Over Self Adjusted

I jacked up the front of the car and when I was done the rear drum brake was seized up tight.
I get the feeling this is from the self adjustment mechanism.

Is there any way to get it to loosen with out having to take the brake apart?

Thanks for any input.

These self adjusters just can do what your thinking. In any car. You will need to get in there to see just what si wrong. Drum or disk. It's most Likely something to do with the pivot for the emergency brake or the cable stuck in the housing. Do clean and Lynn the threads in the adjuster. To keep it working well.

I was hoping to not have to open it up.
It's back to the PT for me.

Jacking up the front of the car and having the rear wheel seize is terrible.
I was lucky that It wasn't from a flat front tire out on a stretch of lonely highway.

So I think I am going to disable the parking brake and avoid this potential problem in the future. My PT is an automatic so I can live without it.

Anyone know the best way for me to disable the parking brake?

As always, any replies are always appreciated. Thanks

Not something I recommend. If you have inspections in you state you may also be required to have it function. Come in handy when jacking up the pt. keep jack from rolling over.

My money says it's the emergency Parking cable that is seizing. If the self-adjusters are seized then there would not be any adjusting and that wheel will not have proper braking.

Well I opened it up today and got things unstuck.

There is a little window on the back side of the brake that you can open by removing a rubber plug.
I did that first, however it is an incredibly tight space to work in, especially if you are lying on your back under the car.
So I took off the wheel and pried the drum off the seized up brake very carefully using a Stanley crowbar. It worked really well.
A little on the left and then a little on the right, being careful not to damage the brake shoes.
Then I adjusted the offset of the shoes by turning the star wheel.
This is where I used the little window on the back side.
I could hold the dogleg off the the star wheel with one hand and with the other I inserted a flat blade screw drive in the window and turned the star wheel downwards to loosen.
Worked like a charm. I cleaned out the brake dust and lubricated where I could.
Nothing else was out of place. The hand brake seemed fine so I left it alone.
I guess I have to chalk it up to one of those special PT moments.

you can do this and loosen the shows but that wasn't the problem. Self adjusters can't create this condition. You still missing something in the park break system. You will eventually find this out. Would not be surprised if you only drag one wheel with the hand brake on. This will also course excessive ware on the brake shoes on one end.
