Why is the car handbrake warning light on?

[Toby]

The reasons for the handbrake light to illuminate are as follows: 1. Handbrake not fully released: It is possible that the handbrake has not been truly released to its position. Even if the handbrake is released, it may not press the switch. In this case, the driver should repeatedly confirm whether the handbrake is in place. 2. Insufficient brake fluid: Lack of brake fluid can also cause the handbrake light to illuminate. When the brake fluid level falls below the safety line, the handbrake light may stay on continuously, or there may be false alarms. For example, when driving uphill or braking sharply, due to excessive slope or fluid turbulence, the fluid level indicator may give a false alarm. For such occasional alerts, if the brake fluid is indeed low, adding an appropriate amount of brake fluid can turn off the handbrake light. 3. Brake pad issues: Worn brake pads or foreign objects entering can also cause the handbrake light to stay on. Because the surface of the brake disc has become uneven, stepping on the brake may also be accompanied by sharp metal friction sounds. This situation can also lead to insufficient braking force, longer braking distance, and softer braking. In this case, simply replacing the brake pads can solve the problem.
