1. On each of the rear combination brake chambers, a special release stud
tool is carried in a storage socket cast into the body of the chamber. Re-
move the nut and washer from the end of the release stud tool, and re-
move the tool from its socket.
2. Remove the rubber dust cap from the access hole in the upper end of the
spring brake chamber. Insert the toggle end of the release stud tool into
the access hole. Be sure that the tapered end of the tool has entered the
hole in the piston inside the chamber. Insert the tool until it bottoms.
3. Rotate the release stud tool a quarter turn clockwise and pull outward,
to engage the toggle end with the piston. While holding the bolt in its
engaged position, install the washer and nut onto the end of the tool.
Turn the nut down against the flat washer until finger tight.
4. Using a 3/4” hand wrench, (do not use an impact-type wrench), turn the release nut clockwise until the internal spring is fully caged.
5. Repeat the procedure for the spring brake chamber on the opposite side of the bus. The spring brakes are now released, having their
springs compressed by the release bolts.
6. The bus is prepared for towing. The bus may be equipped with optional tow hooks or tow eyes, located just inside the access open-
ings of the front and/or rear bumper.
