TECH TIPS: CAGING A BRAKE CHAMBER
WARNING: Spring Brake Chambers are under extreme pressure and can cause serious personal injury, especially if caging is attempted by anyone not experienced in servicing these units. It is good practice to
always stand to the side of the spring brake when caging or releasing. • Remove dust cap and release bolt from side of the center section. Re‑attach the washer and nut to the bolt. •
• Once properly seated, screw the nut and washer up to the housing, by hand at first while making sure the T‑end remains seated inside the spring plate groove. • With a hand wrench, torque the release bolt nut to ±20 ft‑lbs. NEVER use an impact wrench as you will likely damage the unit and/or possibly cause the main spring to release, potentially causing bodily harm. • The RELEASE BOLT is now holding the parking spring in the collapsed position so you can SLOWLY RELEASE the air pressure from the unit. • NOTE: The threaded end of the release bolt will extend roughly 2‑1/2” or more out of the nut when the spring brake chamber is fully caged.
Then, you must SECURE the brake chamber on a table and apply between 100‑120 psi to the parking side inlet port marked PARKING / 12. Maintain this pressure throughout this caging procedure. • Insert the T‑end of the RELEASE BOLT into the parking side bolt‑hole until contact with the spring plate. Turn the RELEASE BOLT CLOCKWISE 180° while pulling slightly. The T‑end will slide into a GROOVE. Once seated, for safety, try turning the RELEASE BOLT back and forth a few times ensuring a proper connection.
