Yes, there are parking brakes and service brakes. If you look at your rear axle there should be two chambers. One contains a massive spring to apply the parking brake. The other is the service brake. It normally takes about 30# of air to compress and hold it out of the way. If you look at your steer axle there is only 1 chamber on each wheel (service brake)
Air Brake pump down procedure
I'd try backing up 1st, then tap the metal part of the brake shoe with a hammer to bust it loose. Common on a truck that's sat.
But ONLY ONE SET OF BRAKE SHOES! Don't confuse the issue.
OK, I'm confused. Never said there were more than one set of brake shoes. Perhaps people who have air brakes on their RV's should have to have an "air brake endorsement" on their drivers license. The air system contains two braking systems in one. Service and parking (aka emergency). Both systems operate the same set of brake shoes.
Have a nice day.
