Parked my 97 bluebird with air brakes in January and haven't released the parking brake since. Now when I push the button to release it I don't hear that nice escape of air. Any ideas where to start? I'm thinking somethings just stuck
The tanks seem to air up. One makes a whining noise until it's full of air. I have some valves labeled wet, back brake and front brake and I drained the air out of those and let the tanks fill up and they still wouldn't release. I am going to go check it out more tomorrow but am not familiar with air brakes so it's hard for me to speculate on what could be wrong. I was hoping maybe something just got a little stuck
Agree with @kool4skool. Just make sure you chock the wheels REAL good. The shoes tend to rust/stick to the drums when it is parked. We would sometimes hammer the shoes EASY if there is room in the backing plate.
Eric, it would be good for your bus in the long run if you at least warm it up once in a while during the winter. Take it for at least a 15 minute drive every couple weeks so the engine warms and other moving parts move.
