BRC 522279.13 – Uncalibrated Secondary Brake Control Valve. John Deere System Advisory.

BRC 522279.13 (BRC )

Code: 522279.13



Error code BRC 522279.13 indicates that the secondary brake control valve has not been calibrated properly. This lack of calibration can result in suboptimal braking performance, potentially leading to uneven or delayed brake application, which could affect vehicle safety and handling.


Due to the calibration issue, the function of the secondary brake control valve is degraded. While the brake may still function, it does not perform to its full capacity, which could compromise the effectiveness and responsiveness of the braking system.


  • Perform Calibration: Follow the manufacturer’s guidelines to calibrate the secondary brake control valve correctly. This may involve specific diagnostic tools and software to ensure precise adjustment.
  • Inspect Valve and Associated Components: Before recalibration, inspect the valve and any associated mechanical and electrical components for wear, damage, or malfunction that could hinder proper calibration.
  • Test System Functionality: After calibration, thoroughly test the braking system under various conditions to ensure the valve functions as expected.
  • Regular Maintenance and Checks: Incorporate regular calibration checks into the maintenance routine to prevent future issues with valve calibration.
  • Consult Technical Support: If difficulties with calibration persist, consult technical support or a professional technician with experience in hydraulic braking systems for guidance and assistance.


Proper calibration of brake control valves is crucial for maintaining the precision and safety of the braking system. Ensuring that this procedure is carried out accurately and routinely will help maintain optimal vehicle performance and prevent braking irregularities.
