Common Causes of the Warning Light
Several factors can trigger the check brake system warning. Here are some of the most common culprits:
- Low Brake Fluid: This is the most frequent reason. A leak in the brake lines or worn brake pads can deplete the brake fluid level, triggering the warning light.
- Worn Brake Pads: Brake pads are designed to wear down over time. When they become too thin, sensors trigger the warning light.
- Faulty ABS System: A problem with the Anti-lock Braking System (ABS) can also illuminate the warning light. This often requires specialized diagnostic equipment to pinpoint.
- Parking Brake Engaged: Sometimes, the simplest explanation is the correct one. If your parking brake is even slightly engaged, it can trigger the warning.
- Faulty Brake Light Switch: A malfunctioning brake light switch can also cause the warning light to come on.
