A flashing brake warning light on your 2011 Subaru is a serious safety concern that should never be ignored. It typically indicates a problem with your braking system that requires immediate attention. This article will guide you through the potential reasons behind a flashing brake warning light on your 2011 Subaru and provide insights into diagnosing and addressing the issue.

Common Causes of a Flashing Brake Warning Light
Several factors can cause the brake warning light to flash on your 2011 Subaru. Here are some of the most common culprits:
1. Low Brake Fluid Level
One of the primary reasons for a flashing brake warning light is low brake fluid. Brake fluid is essential for transmitting force from your brake pedal to the wheels, allowing your car to stop. A leak in the brake lines or a worn-out brake caliper can cause a drop in brake fluid level, triggering the warning light.
“Always check your brake fluid level as part of your routine car maintenance. It’s a simple step that can prevent major brake problems,” advises John Miller, a certified automotive technician with over 15 years of experience specializing in Subaru vehicles.
2. Worn Brake Pads
Brake pads are designed to wear down over time. As you apply the brakes, the pads press against the brake rotors, creating friction to slow down and stop the vehicle. When the brake pads wear down to a certain level, a sensor triggers the brake warning light, signaling it’s time for a replacement.
3. ABS Issues
Your 2011 Subaru is equipped with an Anti-lock Braking System (ABS), designed to prevent wheel lockup during hard braking. The ABS system relies on sensors to monitor wheel speed and modulate brake pressure. If the ABS module detects a problem with any of its components, it can trigger the brake warning light to flash.
4. Faulty Brake Light Switch
While less common, a faulty brake light switch can also cause the brake warning light to flash. The brake light switch activates your brake lights when you press the brake pedal. If this switch malfunctions, it can disrupt the brake light circuit, potentially leading to a flashing warning light.
What to Do When Your Subaru Brake Warning Light Flashes
A flashing brake warning light demands immediate attention. Here’s what to do:
- Safely pull over: As soon as it’s safe, pull over to the side of the road and come to a complete stop.
- Check your brake fluid level: Refer to your owner’s manual for the location of the brake fluid reservoir and instructions on how to check the fluid level. If the fluid level is low, adding more fluid might temporarily solve the issue, but you still need to take your Subaru to a mechanic to diagnose and repair the underlying cause of the leak.
- Avoid driving: If the brake fluid level is significantly low or you suspect any other issue with the braking system, avoid driving your Subaru. Driving with compromised brakes is extremely dangerous and can lead to accidents.
- Contact a qualified mechanic: Reach out to a trusted mechanic specializing in Subaru vehicles to diagnose and repair the issue. They have the expertise and equipment to identify the root cause of the problem and ensure your braking system functions correctly.
Preventing Future Brake Warning Light Issues
Proactive maintenance is crucial for preventing future brake problems. Here are some tips:
- Regular brake inspections: Have your brakes inspected by a qualified mechanic at least once a year or as recommended in your Subaru’s owner’s manual.
- Timely brake pad replacement: Replace your brake pads before they wear down too much. Consult your owner’s manual or a mechanic for the recommended brake pad replacement interval for your 2011 Subaru model.
- Quality brake fluid: Use high-quality brake fluid that meets your Subaru’s specifications. Check your owner’s manual or consult with a mechanic for the recommended brake fluid type.
