Here's a breakdown of the likely causes and why professional help is recommended:
* Low Brake Fluid: This is the simplest and most common cause. Check the brake fluid reservoir (usually a clear plastic container near the master cylinder) and add fluid if it's low. However, low fluid is a symptom, not the root cause. Something is making the fluid leak, and that needs to be found.
* Brake System Leak: A leak in any part of your brake system (lines, calipers, wheel cylinders, master cylinder) will cause low fluid and activate the warning lights. This requires professional inspection and repair to locate and fix the leak.
* Brake Wear: Worn brake pads or shoes can trigger the warning light, but usually wouldn't illuminate the ABS light unless a sensor is also involved.
* ABS Sensor Problems: One or more of the ABS wheel speed sensors might be faulty, dirty, or damaged. These sensors are vital for the ABS system to function. Diagnosis requires specialized tools.
* ABS Module Failure: The ABS control module itself could be malfunctioning. This is a more complex and expensive repair, usually requiring professional diagnostics and potentially replacement.
* Wiring Issues: Damaged or corroded wiring related to the brake system or ABS system can cause erratic behavior and illuminate the warning lights.
What to do:
1. Don't drive the van until this is fixed. Driving with brake problems is extremely dangerous.
2. Check the brake fluid level immediately. Add fluid only if it's low, and then get it checked ASAP. Adding fluid masks the problem, doesn't solve it.
3. Take the van to a qualified mechanic or a reputable auto repair shop. They have the diagnostic tools and expertise to pinpoint the exact cause of the problem and make the necessary repairs safely.
Ignoring these warning lights is incredibly risky. The cost of repairs is far less than the cost of an accident caused by brake failure. Get it checked by a professional as soon as possible.
