Common Causes of a Persistent Brake Warning Light

Several factors can trigger the brake warning light to illuminate and stay on. These include:

• Low Brake Fluid: This is the most common culprit. A leak in the brake lines, worn brake pads, or a faulty master cylinder can deplete brake fluid levels, triggering the warning light.
• Parking Brake Engaged: Sometimes, the simplest explanation is the correct one. Ensure the parking brake is fully released.
• Faulty Brake Light Switch: The brake light switch activates the brake lights when you press the brake pedal. A malfunctioning switch can also trigger the brake warning light.
• Worn Brake Pads: As brake pads wear down, they reach a point where a sensor triggers the warning light, indicating it’s time for replacement.
• ABS Issues: Problems with the Anti-lock Braking System (ABS), such as a faulty sensor or module, can illuminate the brake warning light. Often, the ABS light will also be on.
• Faulty Master Cylinder: The master cylinder is the heart of the hydraulic braking system. A leak or internal failure can cause the brake warning light to illuminate.

Troubleshooting a Brake Warning Light

Here’s a step-by-step guide to help you diagnose the problem:

1. Check the Parking Brake: Make sure the parking brake is fully disengaged.
2. Inspect Brake Fluid Level: Locate the brake fluid reservoir and check the fluid level. If it’s low, add the correct type of brake fluid recommended for your Chevrolet model. If the level drops again quickly, suspect a leak.
3. Check Brake Lights: Have someone observe the brake lights while you press the brake pedal. If they don’t illuminate, the brake light switch may be faulty.
4. Inspect Brake Pads: Visually check the brake pads through the wheel spokes. If they appear thin or worn down to the metal backing plates, they need replacement.
