Help! Parking brake stuck!

I haven't driven my bus since driving Alaska to Georgia in February. I never washed salt off my undercarriage and now my parking brake is stuck and won't disengage. What should I do?

Often enough rust can develope on the drums when sitting for a long period of time to cause them to stick. Block the wheels and if you're comfortable doing so you can back off the slack adjusters and hammer on the drums a bit, this might be enough to free them up. You are sure you have enough air pressure to overcome the spring brake?

I agree. Rusted brake lining to the drums. Build air, release brakes, and beat drums with a big hammer.

I rocked back and forth until it broke free.

Excellent!
Take her for a little cruise and lightly ride the brakes a bit to clean them up.
