What causes the Golf 7 to display a brake failure warning?

The reasons why the Golf 7 displays a brake failure warning are as follows: Severe brake pad wear: Brake pads are divided into two types, those with sensor lines and those without. Those with sensor lines will automatically connect the circuit when the brake pads wear to the limit position, at which point the warning light will illuminate. The brake pads need to be replaced; Brake fluid level too low: Insufficient brake fluid will also be accompanied by significantly reduced braking force, and in severe cases, a complete loss of braking force may occur. The warning light will illuminate in this situation. Simply replenish the brake fluid in time; Brake system oil leakage or false alarm: This directly affects the vehicle's technical performance, leading to waste of lubricating oil and fuel, power consumption, affecting the cleanliness of the vehicle, and causing environmental pollution. The warning light will illuminate, and the issue can be resolved by replacing the gasket or oil seal.
My Golf 7 also had a brake failure warning before. That time it was because the brake pads were worn too thin, and the sensor detected insufficient thickness, triggering the alarm. The braking system of the Golf 7 is quite advanced in design, but brake pads are consumables that need replacement every few tens of thousands of kilometers, especially if you often drive in congested urban areas where frequent braking accelerates wear. Additionally, insufficient or deteriorated brake fluid can also trigger a fault warning. When the fluid level is below the standard, it affects hydraulic transmission, reducing braking performance. I recommend checking the brake fluid reservoir first to see if it needs topping up or replacing. At the same time, have the repair shop use a diagnostic tool to read the fault codes and confirm the root cause of the issue. Don’t overlook minor bugs like software errors in the ABS module. During regular maintenance, I make it a habit to inspect these components in advance—it’s both safer and more reassuring, as braking issues are not something to take lightly.
Having driven the Golf 7 for several years, I was really startled when the brake failure warning popped up. Later, I found out it was caused by dust accumulation on the sensor leading to poor contact. The Golf 7's electronic braking system is sensitive to environmental factors—even minor dust or water ingress can trigger false alarms. Common causes also include warped or rusted brake discs, which lead to uneven friction and trigger warnings, requiring immediate resurfacing or replacement; loose wiring connections are also frequent culprits, and simply tightening them might solve the issue. Whenever the warning appears, I immediately slow down and pull over, avoiding continued driving, then head straight to a professional shop for inspection—never try to tough it out to save trouble. Paying attention to routine maintenance, such as regular checks on brake discs and wiring, can reduce such sudden incidents and ensure driving safety. After all, car issues aren’t just costly—they can also endanger others.
