What Causes the Car Brake Warning Light to Illuminate?

[DelCaroline]

The reasons for the parking brake warning light to illuminate are as follows: 1. The handbrake is not fully released: Although the handbrake is released, it may not press the switch properly. In this case, the driver should repeatedly confirm whether the handbrake is fully engaged. 2. Lack of brake fluid: Insufficient 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 constantly. Additionally, when driving uphill or braking sharply, the steep angle and fluid movement can trigger a false alarm from the fluid level indicator. 3. Worn brake pads or foreign objects in the brake pads: These issues can lead to insufficient braking force, longer braking distances, or a spongy brake pedal, resulting in the handbrake light staying on.
