CHEVY BRAKE SHOE ADJUSTER LOCKUP

1984 Chevrolet Truck

Brakes problem
1984 Chevy Truck V8 Two Wheel Drive Automatic 120000 miles

In adjusting the left rear brake shoes, I turn the adjuster sprock too far so it is in a jammed condition, and cannot back off.

Thanks for your response.
A small screwdriver bends and then slips of the sprocket without a budge of the adjustment.
I tried to heat the drum with a plumbers torch to expand the drum and free the adjuster, but the drum is huge (a P30 chassis).
With the dual wheels off the ground, I tried to spin the wheels, with the engine to heat the drum, this just torqued the vehicle.
I'm thinking I may have to cut a bigger hole in the backplate to enable more torque on the sprocket.
Any other ideas?

Thanks, Jim

Maybe good idea other option is big puller and rip shoes springs hold downs off.

The solution was to use a screwdriver as a chisel and tap the sprocket.
Thanks, Jim
