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?
