Common Causes of the Emergency Brake Warning Chime
Low Brake Fluid
One of the most common culprits behind the incessant chime is low brake fluid. This is a serious issue that shouldn’t be ignored, as it could indicate a leak in your brake system. Check your brake fluid reservoir and top it off if necessary. If the fluid level continues to drop, seek professional help immediately.
Faulty Brake Light Switch
The brake light switch, often located near the brake pedal, is responsible for activating your brake lights when you press the pedal. A malfunctioning switch can sometimes trigger the emergency brake warning chime. Testing the switch with a multimeter can help determine if it’s the source of the problem.
Worn Brake Pads
Worn brake pads can also activate the warning chime. As your brake pads wear down, the brake fluid level in the master cylinder decreases. This can trigger the low brake fluid warning, which in turn activates the chime. It’s essential to regularly inspect your brake pads and replace them when necessary.

Stuck Parking Brake Cable
Sometimes, the parking brake cable can become stuck or corroded, preventing the parking brake from fully disengaging. This can cause the warning chime to persist even when the lever is released. Lubricating the cable or replacing it altogether might be necessary. For example, some Passat owners have experienced a persistent parking brake warning light. You can read more about that specific issue on our parking brake warning light Passat article.
Diagnosing the Emergency Brake Warning Chime
Visual Inspection
Start by visually inspecting the parking brake lever and cable for any signs of damage or obstruction. Check the brake fluid reservoir and ensure the fluid level is within the recommended range.
Testing the Brake Light Switch
Use a multimeter to test the brake light switch for continuity. This will determine if the switch is functioning correctly. If the switch is faulty, replacing it is a relatively simple procedure.
Checking Brake Pad Thickness
Inspect the brake pads for wear and tear. Measure the thickness of the pads and compare it to the manufacturer’s specifications. Replace the pads if they are worn beyond the recommended limit.
