What Causes the Handbrake Light to Illuminate on the BYD Surui?
2 Answers
Brake lights are typically installed at the rear of the vehicle, featuring a red main body color to enhance light penetration. This ensures that following vehicles can easily detect when the vehicle ahead is braking, even under low visibility conditions, thereby helping to prevent rear-end collisions. The reasons for the Surui's brake light staying illuminated are as follows: 1. Low brake fluid level: If the brake fluid falls below the safety line, it can cause the brake light to remain on. 2. Faulty brake switch system or circuit sensor: This issue requires professional tools and equipment for diagnosis and repair, so it is recommended to visit a 4S shop for inspection and maintenance. 3. Excessive brake pad wear: If the brake light stays on and braking performance declines, it can be determined that the brake pads are excessively worn.
Friends driving the BYD Surui, don't panic when the handbrake light comes on—it's usually not a minor issue. The most common reasons are the handbrake not being fully released or getting stuck; try pulling and releasing it a few times. Another major issue could be low brake fluid levels. When the brake fluid is insufficient, the light will stay on as a warning, indicating possible fluid leakage or severely worn brake pads. In the BYD Surui, sensor malfunctions are also quite common, such as a short circuit in the handbrake position switch or poor wiring contact, leading to system misjudgment. Other causes, like overall brake system failure or dashboard issues, can also trigger this light. Based on my experience, I recommend starting with simple checks: after starting the car, ensure the handbrake lever is fully down, then check the brake fluid reservoir in the engine bay to see if the fluid level is below the MIN mark. If the fluid level is normal but the light remains on, it's best to visit a professional shop for a diagnostic scan. Regular maintenance of brake components is crucial. Checking the fluid level weekly can prevent major repairs and ensure safe driving—after all, the risk of brake failure is too high to ignore small issues.
