Air brakes

As the others have said, but I would warm it up and put it in reverse. Also, if you have a wooden peg and rubber mallet and can reach the drums, thump them a little bit. :)

If you have drum brakes and the coach has been sitting for awhile the shoes may have rusted to the drums. Sometime it doesn't take long especially if they were wet when you parked.
The best way I have found is like said above just put it in reverse and give it some throttle and if that doesn't work try forward and then backward. It will release with a bang. It is a fairly common problem with drum brakes.

Please tell us what coach/chassis you have. We don't know if you have air drum or disk brakes OR gas chassis with drive line brake.

You say "pad", is this common on disk brakes?

As said use Reverse then Forward then Reverse with some good pedal, BE ready to brake and it will make a good bang most of the time when the pads release. Very common to happen.

Common when they sit for a long time. You or a mechanic may need to get under the rig and beat the drums until they release.

Mine have done that. Assuming your pressure is up which releases the automatic parking brakes, I put it in reverse and give it some pedal.

How long since it was last driven?

Is it building up 100 to 125 PSI of air pressure?
