Caging the Spring or Parking Brakes???
We’ve all probably heard of “caging the brakes” if there is a catastrofic air system failure, RIGHT? Until now I would have been at the mercy of a wreaker driver to know whats what. Not no mores When you change out your brake chambers for new, you learn real quick.
On the left is our new 1624 piggyback brake chamber, on the right is our new drive axle 3036 piggyback chamber. New out of the box they come “caged”. That’s what the big bolt/nut looking thing sticking out of the top is. Notice it isn’t a bolt w/a hex head. It has 2 prongs instead. In the pic I have my old caging setup(bolts) lying just below the hole in the can where they are stored.

Our air brake systems should not be intimidating, but they should be respected.
When your coach is parked with the parking brake “on” there is no air pressure going to the brake chamber.
Caging a parking brake is using the threaded “T” bolt lonestar pictured to retract the spring that applies the parking brake. The service brakes are applied with air pressure, the parking brakes are applied with spring pressure, and released with air pressure which compresses the spring.
Pay attention to what lonestar is showing and telling. His posts are good and worth learning.
