Common Causes of the Service Brake System Warning
Several factors can trigger the “Service Brake System” warning in your GMC Sierra. Here’s a breakdown of the most common culprits:
- Low Brake Fluid: This is often the easiest fix. Over time, brake pads wear down, and the brake fluid level drops.
- Worn Brake Pads: Thin brake pads can activate the warning light. Regular brake inspections are essential.
- Faulty ABS Sensors: The Anti-lock Braking System (ABS) relies on sensors to function correctly. A malfunctioning sensor can trigger the warning.
- Brake Light Switch Issues: A faulty brake light switch can sometimes cause the service brake system warning to illuminate.
- Wiring Problems: Damaged or corroded wiring within the braking system can disrupt communication and trigger the warning.

- Inspect the Brake Pads: Visually inspect your brake pads for wear. If they appear thin, it’s time for replacements.
- Check the Brake Lights: Have someone help you verify that all your brake lights are working correctly.
