Seized brake shoes.

[Polywobblydriver]

Suggestions please. This problem is on an 1984 Porsche 924. Here are the facts so far. BOTH rear drums are seized solid. It has been parked unused for 10 years, (yes ten). Hand brake OFF, IN gear. It is now up on axle stands. The drums won't turn AT ALL! I've sprayed it regularly with penetrating oil. I've tried to slacken the adjusters, they're seized too. I've had the castle nuts off, the drums are that tight they came off easily. The drum puller just pushed the drive shafts out. I've tapped them with a hammer but I'm cautious of hitting them too hard. What else can I do?

Hit them harder

Its the only way

[Polywobblydriver]

Would heat help? How hard can you hit the drums without breaking them?

Let me get this right.

It has been stood for 10 years & you aren't planning on changing them anyway?

Hammer them until they split if you have to, they are toast already.

I only need to get her rolling to put her on a trailer. It's up for sale as a project.

OK, apologies, the only way I have ever done it is with a whack!

If the handbrake was off & the drums have seized I would guess the issue may be build up of rust between the drums and the shoes, so all you can do is try harder.

Is there even the slightest bit of movement back & forth?

[Polywobblydriver]

There is no movement at all, both sides. They are that solid the castle nuts came off easily and they are set at a seriously high torque setting.

I asked if there was the slightest bit of movement in case it could be the diff.

LARGE hammer, LOTS of heat, BIG whack, hope for the best.

[Polywobblydriver]

Thanks every one for helping.
Theres not even any slack movement. Everything is locked solid.
Not even a 3 foot long 3/4 drive breaker bar will move it.
I'll see if I can drop a drive shaft to see if that makes any difference.

As said, blow torch, BFO hammer, long pole between wheel bolts to rock it back and forth

A big dead blow hammer is very useful for freeing stuck drums.

I've had to angle grind drums off before.

I've got a big square lump hammer I can hit it with. Swearing loudly at it as well will probably help a lot.
