Understanding Your Buick LeSabre’s Brake Warning Light
The brake warning light is designed to alert you to potential problems within the braking system. Ignoring this light could lead to serious safety hazards.
Common Causes of the Brake Warning Light
- Low Brake Fluid: This is the most common culprit. Check your brake fluid reservoir and top it off if necessary. However, consistently low brake fluid indicates a leak, requiring immediate professional inspection.
- Worn Brake Pads: Brake pads have wear indicators that trigger the warning light when they reach a certain thinness. Replacing worn brake pads is a standard maintenance procedure.
- Faulty Brake Sensor: Sometimes, the sensor itself malfunctions, triggering the light even if there’s no actual problem. A diagnostic scan can pinpoint a faulty sensor.
- ABS Issues: If the Anti-lock Braking System (ABS) light is also on, the issue might lie within the ABS module or sensors. This often requires specialized diagnostic tools.
- Parking Brake Engaged: Ensure the parking brake is fully released. Sometimes, a slightly engaged parking brake can trigger the warning light.
