* Low Brake Fluid: This is the most common cause. Low brake fluid suggests a leak somewhere in the system. A leak can be in the lines, calipers, master cylinder, or even a wheel cylinder. This is a serious safety issue and requires immediate attention. Do not drive the vehicle until it's checked.
* Brake System Malfunction: A sensor within the ABS system (wheel speed sensor, ABS module, etc.) might be faulty. This prevents the ABS from functioning correctly, and the system may trigger the warning lights as a precaution.
* Brake Pad Wear: While less likely to trigger *all three* lights at once, extremely worn brake pads can sometimes lead to issues detected by the system's sensors, potentially leading to the warning lights.
* Parking Brake Engaged: Though less likely given the context of the other lights, ensure your parking brake (emergency brake) isn't partially engaged.
* Electrical Issues: A problem with the wiring harness related to the braking system could also cause this.
What to do:
1. Do not drive the car. Driving with a possible brake system problem is extremely dangerous.
2. Check the brake fluid level. The reservoir is usually a clear plastic container that you can easily locate under the hood. If it's low, there's a leak somewhere in the system.
3. Inspect your brake pads (if comfortable doing so). Extremely worn pads might trigger warning lights but this is less likely to trigger all three.
4. Have the vehicle inspected by a qualified mechanic immediately. They'll use diagnostic tools to pinpoint the exact problem and safely repair it. This is crucial for your safety.
Ignoring these warning lights is incredibly risky. A brake system malfunction can lead to loss of braking power and potentially serious accidents. Professional attention is necessary to diagnose and resolve the problem.
