Re: brake pedal "sticking" w/air brakes?
My brake pedal does the same thing, ultimately I'd suggest replacing the pedal. In the meantime do what I do, squirt the hinges with WD-40, CRC or something similar and work the pedal up & down a bit and that should fix it up for now!
You just might be a Redneck if...
...your motor home used to be a school bus!
...Your living room has a steering wheel!
...Your home has brake lights
