Installation & Maintenance

Installing the Carlson's choke tube flush mount is straightforward:

1. Depressurize the brake system and secure the work area.
2. Remove the existing choke tube using the appropriate wrench.
3. Inspect the mounting surface for any damage or corrosion; clean if necessary.
4. Align the new 20 GA tube with the BER mounting brackets.
5. Tighten the mounting bolts to the manufacturer‑specified torque (typically 35 Nm).
6. Re‑pressurize the system and perform a leak test according to AAR guidelines.

For optimal longevity, schedule routine inspections every 6 months or 12,000 miles, whichever occurs first. Replace the tube immediately if any signs of wear, corrosion, or airflow restriction are detected.
