If your brake system warning light comes on, it means there is a problem affecting the safety of your braking system. This warning should never be ignored, as it can indicate anything from low brake fluid to a major hydraulic failure. Driving with the brake warning light illuminated is unsafe and requires immediate attention.

What does the brake system warning light mean?

The brake system warning light is designed to alert you to issues within your braking system. It may indicate:

• Low brake fluid level in the reservoir
• Worn brake pads or shoes (on vehicles with wear sensors)
• A leak in the hydraulic system
• Parking brake engaged or not fully released
• Faulty master cylinder or ABS-related issues

Why do you need to fix this problem quickly?

The braking system is the most important safety feature on your vehicle. If the warning light is on, your brakes may not work as designed, which can lead to dangerously long stopping distances or complete brake failure. Immediate inspection is essential to avoid accidents.

How do you know when to get it checked?

The warning light may come on under these conditions:

• When pressing the brake pedal, the light flashes or stays on
• The light appears while driving, even if the handbrake is released
• Brake pedal feels spongy, soft, or sinks to the floor
• Unusual noises, vibrations, or poor braking performance

What happens during an assessment?

A mechanic will:

1. Check the brake fluid level and condition
2. Inspect brake pads, shoes, rotors, and drums for wear
3. Look for leaks in hoses, calipers, wheel cylinders, and master cylinder
4. Check the operation of the parking brake
5. Scan the vehicle’s computer system for ABS or electronic brake faults
6. Advise on necessary repairs to restore safe operation

How much does it cost to fix?

Costs depend on the cause. A simple fluid top-up or handbrake adjustment may cost under $100. Replacing brake pads or hoses typically costs $200–$500, while repairing master cylinder or ABS faults can range from $400–$1,200+.

Is it unsafe to drive with the brake warning light on?

Yes. The brake system warning light indicates a fault that may affect your ability to stop safely. Driving in this condition is dangerous, and the vehicle should be inspected and repaired immediately.
