Understanding the Brake Warning Light
The brake warning light is part of your car’s essential safety system. It can illuminate for several reasons, not all of which indicate a critical problem. However, ignoring this light can lead to significant safety risks and potentially costly repairs.
Common Causes of a 2009 Impreza Brake Warning Light
- Low Brake Fluid: This is the most common culprit. Low brake fluid can indicate a leak in the brake lines or worn brake pads.
- Worn Brake Pads: Brake pads have wear indicators that trigger the warning light when they reach a certain thickness.
- Faulty Brake Sensor: A malfunctioning brake sensor can also trigger the light even if the brake system is functioning correctly.
- Parking Brake Engaged: Sometimes, the simplest explanation is the right one. Make sure your parking brake is fully disengaged.
- ABS Issue: While less common, a problem with the Anti-lock Braking System (ABS) can also illuminate the brake warning light.

Diagnosing the Problem
Start by checking your parking brake. If it’s disengaged, move to checking the brake fluid level. If the level is low, you might be dealing with a leak. Look for signs of fluid leakage around the brake lines, calipers, and master cylinder. If you suspect a leak, it’s essential to have a professional mechanic inspect your brake system immediately.
What if the brake fluid level is okay? Then the next step involves checking the brake pads. Worn brake pads require immediate replacement.
If the brake fluid and pads are fine, a faulty brake sensor or an ABS issue might be the cause. Diagnosing these issues usually requires specialized diagnostic tools and expertise.
Solutions and Repairs
- Adding Brake Fluid: If the fluid is low, add the correct type of brake fluid recommended for your 2009 Impreza. Don’t overfill.
- Replacing Brake Pads: Worn brake pads should be replaced immediately by a qualified mechanic.
- Repairing Brake Lines: Leaking brake lines are a serious safety hazard and require professional repair.
- Replacing Brake Sensor: A faulty brake sensor needs replacement. This is usually a straightforward procedure for a mechanic.
- Addressing ABS Issues: Diagnosing and repairing ABS problems usually involves specialized equipment and expertise.
