Brakes locked on Holiday Rambler

[KPruitt]

RV has only been setting for about two months
Air brakes will not unlock
Have hit drums with hammer
Have rocked RV back and forth
What can I do next to unlock brakes???

[sch911]

I assume you have adequate air in the system, and the parking brakes are off right?

[KPruitt]

It's the break. Pads pressed against the drums.

Drums? Mine have before. Freightliner. I put it in reverse and mashed the pedal.

Will they release using the caging bolt?
