Possible Causes:
* Low Brake Fluid: This is the most common and easiest to check. Low brake fluid indicates a leak somewhere in the system. A leak could be in a brake line, caliper, wheel cylinder, or master cylinder. This is a serious safety issue and should be addressed immediately.
* ABS Sensor Issues: One or more of the ABS wheel speed sensors might be faulty, dirty, or have a wiring problem. These sensors tell the ABS module the speed of each wheel. A malfunctioning sensor can trigger the warning lights.
* ABS Module Failure: The ABS module itself could be failing. This is a more complex and expensive problem.
* Brake Light Switch: Although less likely given the ABS light also coming on, a faulty brake light switch could be contributing to the issue. This switch tells the car when the brake pedal is pressed.
* Faulty Brake System Components: Problems with the brake calipers, wheel cylinders (if rear drums), or master cylinder could also cause this.
What to Do:
1. Check the Brake Fluid: This is the most important first step. Locate the brake fluid reservoir (usually a clear plastic container under the hood). Check the fluid level. If it's low, do not drive the car. A low level indicates a leak, which is a serious safety hazard. You need to get it towed to a mechanic immediately.
2. Inspect for Leaks: If the brake fluid is low, carefully inspect brake lines, calipers, and the master cylinder for any signs of leaks (wet spots, dripping fluid).
3. Have it Diagnosed: If the brake fluid level is fine or you've found a leak and had it addressed, you'll need a professional diagnosis. A mechanic can use an OBD-II scanner to read the trouble codes stored by the car's computer. These codes will pinpoint the specific problem.
4. Avoid Driving: Until the problem is diagnosed and fixed, avoid driving the car unless absolutely necessary. Driving with a malfunctioning braking system is extremely dangerous.
In short: The flashing lights and illuminated brake and ABS lights point to a significant brake system issue. Don't delay addressing this – your safety is paramount. Get it checked by a qualified mechanic as soon as possible.
