IMPORTANT INSTALLATION NOTES:
✔ Spring brake chambers contain a high-energy power spring. Installation and service must be completed by trained technicians using approved procedures.
✔ Confirm the application requires a Type 30 chamber with an 8" push rod, 5/8"-18 UNF thread, and 4.75" mounting stud spacing.
✔ Verify both air connections are 3/8"-18 NPTF and reconnect them according to the equipment pneumatic schematic.
✔ Align the push rod with the brake linkage without side loading and set the clevis according to the axle or brake manufacturer’s specifications.
✔ This is a non-caging chamber. Do not disassemble, cut, weld, or attempt to manually release the power spring housing.
