Is There a Problem If the Handbrake Malfunction Light Is On?

There is a problem if the handbrake malfunction light is on. Handbrake not fully released: Forgetting to release the handbrake or the handbrake not being fully released. Abnormal brake fluid: Brake fluid leakage or insufficient brake fluid. Brake abnormality: Caused by thinning brake discs or foreign objects entering the brake pads. Function of the braking system: Mainly composed of the energy supply device, control device, transmission device, and brake, it enables a moving car to decelerate or even stop, maintains a stable speed for a car going downhill, and keeps a parked car stationary. Note that if the handbrake malfunction light remains on, the owner must take the car to a professional repair shop or 4S store as soon as possible for treatment. Using a fault detector for inspection can quickly and accurately locate the fault, and then gradually identify the cause.
When I see the brake warning light illuminate while pulling the handbrake, I believe a detailed analysis is needed. Under normal circumstances, this light simply indicates the handbrake is engaged – nothing to worry about, as I frequently observe this phenomenon during daily driving. However, if the light remains on after releasing the handbrake, or if the brake pedal feels abnormally soft, there might be an issue. Common causes include low brake fluid level (possibly due to leakage), faulty sensors sending false signals, or even problems with the ABS system. During troubleshooting, I would first check whether other dashboard warning lights are on, then inspect the brake fluid reservoir level. If low, promptly top up the fluid but avoid driving the vehicle. If the issue persists, specialized tools should be used to measure circuit voltage. Ignoring a persistently illuminated warning light could be extremely dangerous in emergency braking situations. Therefore, I prioritize safety – whenever in doubt, immediately pull over for inspection or visit a professional repair shop.
