BRC 522280.00 – High Secondary Brake Pressure. John Deere System Advisory.

BRC 522280.00 (BRC )

Code: 522280.00

Shortcode:

Description:

Error code BRC 522280.00 signals that the secondary brake pressure is higher than expected, as indicated by sensor voltage readings that are higher than the calibrated current value. This situation is likely caused by issues within the braking system’s hardware, such as a leaking solenoid valve, a valve stuck open, or a blocked return passage. The Brake Control Unit (BRC) detects this discrepancy between the expected and actual pressure based on the voltage it reads.

Reaction:

The system’s response to this condition is to trigger an informational alarm. This serves to alert the operator of the potential issue without immediately affecting the brake’s operational capabilities.

Recommendations:

  • Inspect Solenoid Valves: Check the solenoid valves for any signs of leakage or damage. Replace or repair any faulty valves to ensure they close properly and do not allow excess fluid to pass.
  • Check for Stuck or Blocked Valves: Ensure that no valves are stuck open and that there are no obstructions in the return passages which could cause a build-up of pressure.
  • Calibrate Brake Sensors: Re-calibrate the brake pressure sensors to ensure accurate pressure readings. Incorrect sensor calibration can lead to false alarms or failure to detect genuine issues.
  • System Diagnostics: Run a full diagnostic check to assess the integrity of the brake system and identify any discrepancies between pressure readings and actual system performance.
  • Regular Maintenance and Monitoring: Implement a routine maintenance schedule for the braking system to regularly check and maintain all components, preventing recurring issues.

Note:

Maintaining the hydraulic integrity and sensor accuracy of the brake system is crucial for safe operation. Regular inspections and timely resolution of issues like pressure irregularities are essential to ensure the braking system functions effectively and reliably under all conditions.
