Brake Warning Light Stays On: 2021 Chevrolet Silverado 1500 T1XX
Repair Instructions

  1. Top Off Brake Fluid

    • If the fluid was low, top off with the recommended fluid.
    • Check for leaks and address any issues found.

  2. Replace Brake Pads or Rotors

    • If pads or rotors are worn beyond specifications, replace them.
    • Remove the caliper bolts, slide the caliper off, replace the pads, and reassemble.
    • Ensure all components are torqued to manufacturer specifications.

  3. Repair or Replace ABS Sensors

    • If a faulty ABS sensor is detected, replace it.
    • Disconnect the wiring connector, remove the sensor, and install the new sensor.
    • Reconnect the wiring and clear fault codes with the OBD-II scanner.

  4. Replace Handbrake Switch

    • If the continuity test failed, remove the faulty switch (usually located under the handbrake lever).
    • Install the new switch and ensure it engages properly with the handbrake lever.

  5. Clear Codes and Test

    • After repairs, use the OBD-II scanner to clear any stored trouble codes.
    • Start the vehicle and check if the brake warning light is off.
    • Test the brakes to ensure they are functioning correctly.
Conclusion

If the brake warning light persists after following these steps, further investigation may be required, potentially involving professional diagnostic equipment or consulting with a dealership. Always prioritize safety when working on the braking system.
