brake-booster is a warning light for the braking system, which typically illuminates when the handbrake is engaged. If the warning light remains on after releasing the handbrake, it may indicate a brake booster malfunction. In such cases, it's necessary to inspect braking components such as brake fluid and handbrake, and generally requires a service station for professional diagnosis and repair. Additional information: Possible causes for brake-booster light illumination include: handbrake not fully released, insufficient brake fluid, or brake pads worn to their limit. brake light illumination: The brake warning light normally remains off during regular operation. If illuminated, it signifies the braking system is active (typically occurs when applying handbrake or foot brake) and should automatically turn off after braking completion. If the brake indicator remains constantly lit, this indicates a malfunction in the braking system.
Having driven for so many years, I've seen the brake booster warning light come on numerous times. Simply put, it indicates an issue with the brake assist system. The brake booster is a component that makes it easier for you to apply the brakes; if it fails, the brake pedal becomes extremely stiff, requiring much more effort to slow down. Common causes include vacuum line leaks, sensor malfunctions, or internal aging of the booster. This is no trivial matter—it can lead to loss of control during emergency braking, significantly increasing the risk of a collision. Always remember, if the light comes on, don't push your luck; pull over safely immediately. It's advisable to visit a professional auto repair shop as soon as possible to inspect the vacuum system, preventing minor issues from escalating into major failures. Also worth noting: if this light appears alongside others like the ABS warning light, the problem could be even more severe. Cultivating good habits like annual brake maintenance—such as checking the integrity of vacuum lines—is crucial. Among all dashboard lights, this is the one you should never ignore, as it's literally a matter of life and death.
