What is the problem when the car handbrake indicator light stays on?
2 Answers
The car handbrake indicator light staying on may be due to forgetting to release the handbrake or the handbrake not being fully disengaged, causing the handbrake light to illuminate. If the possibility of the handbrake is ruled out and the handbrake light remains on, the owner should check the brake fluid, as leakage or insufficient brake fluid could cause the handbrake light to come on. If the handbrake light stays on and is accompanied by body shaking or unusual noises when braking, it is likely due to the brake discs becoming thin or foreign objects entering the brake pads. Note that if the handbrake light stays on, the owner must take the car to a professional repair shop or 4S store as soon as possible for treatment. The braking system mainly consists of energy supply devices, control devices, transmission devices, and brakes, and its main functions are to decelerate or even stop a moving car, maintain a stable speed for a car going downhill, and keep a parked car stationary. Using a fault detector for inspection can quickly and accurately locate the fault, and then gradually find the cause.
I've been driving for over ten years and have encountered the handbrake warning light coming on several times, which is quite frustrating. The most common reason is that the handbrake isn't fully released, possibly due to insufficient force when pulling the lever or parking on an uneven surface causing the lever to get stuck. Another situation is when the brake fluid level is too low—the normal level should be at the middle mark of the reservoir, and dropping below that can easily trigger the warning light. If you hear unusual noises while driving or notice the brakes feeling softer, it might be due to worn brake pads causing the fluid level to change. I've also experienced issues with loose or aged sensor connectors, especially after rainy days or driving through water. Never ignore this warning light, as it can interfere with other alert systems. If the brakes fail at high speed, it could be life-threatening. My suggestion is to first try stopping and restarting the car. If that doesn’t work, check the fluid level or take it to a professional for inspection. Also, make it a habit to glance at the braking system during monthly maintenance checks.
