Replacing a brake chamber bracket is a critical task. For fleet uptime and safety, we recommend following these professional steps:
Preparation: Secure the vehicle on a level surface. Release the spring brakes (manually if necessary) and support the axle with jack stands.
Removal: Disconnect the air lines from the brake chamber and remove the chamber from the old bracket. Inspect the bolts connecting the bracket to the axle housing—these often require a high-torque impact wrench due to road grime and rust.
Clean and Inspect: Once the old bracket is removed, clean the mounting surface on the axle housing. Check for any hairline cracks in the axle flange itself.
Fitment: Align the WG9981340034 bracket. It should seat flush against the mounting surface without forced prying.
Torque Specifications: Use new high-strength bolts (Grade 10.9). Tighten to the manufacturer-specified torque (refer to your HOWO service manual) to prevent loosening from road vibration.
Reassembly: Re-mount the brake chamber and reconnect the air lines. Perform a leak test and verify that the pushrod moves freely within the bracket’s clearance.
