Why Does the BYD Han Experience Brake Failure?

[James]

The reasons for BYD Han's brake failure are: 1. Severe overloading; 2. Improper operation; 3. Lack of maintenance in the brake system. The solutions are: 1. Release the accelerator pedal, shift to manual mode, and downshift from high to low gears sequentially, engaging the handbrake with each downshift while pressing the brake release button until the vehicle comes to a complete stop, then shift to park; 2. Utilize terrain or emergency escape lanes to decelerate; 3. Use roadside obstacles to reduce speed. Taking the 2020 BYD Han as an example, it is a mid-to-large-sized sedan with body dimensions of 4960mm in length, 1910mm in width, and 1495mm in height, a wheelbase of 2920mm, a fuel tank capacity of 48 liters, and a curb weight of 2020kg. The 2020 BYD Han is equipped with a 2.0T turbocharged engine, delivering a maximum horsepower of 192PS, a maximum power of 141kW, and a maximum torque of 320Nm, paired with a 6-speed dual-clutch transmission.

I've been driving the BYD Han for a while and think brake failure might be related to improper daily maintenance. Excessive wear on brake pads or warped brake discs can lead to decreased braking power, especially if you frequently drive in congested urban areas where constant braking accelerates wear. Additionally, deteriorated or leaking brake fluid can cause the braking system to fail. I recommend checking the brake fluid level and condition every 20,000 kilometers. Also, when the vehicle's battery is low, electronic power assistance might fail, making the brakes feel heavier, which is more common in electric vehicles. Regular maintenance and timely replacement of wear-prone parts can significantly reduce such issues. If you notice the brake pedal becoming soft or having excessive travel, stop immediately to inspect or visit a professional repair shop.

From automotive repair experience, BYD Han brake failures often stem from system malfunctions. In the braking system, if the ABS module's sensors are damaged or clogged with dirt, it can cause the anti-lock function to fail. Software issues in the electronic control unit may also lead to sluggish brake response, which occasionally occurs after OTA updates. Leaks or air ingress in the brake hydraulic circuit can result in insufficient hydraulic pressure, weakening braking force. I recommend that owners experiencing failure immediately stop to check for tire skid marks, ruling out mechanical jamming. Using diagnostic tools to read fault codes can quickly identify electronic issues. For prevention, avoid modifying the brake system and ensure brake fluid is replaced every two years.

Experienced drivers say that brake issues with the BYD Han are often caused by improper regenerative braking settings. Under hybrid braking, if the energy recovery of regenerative braking is not properly adjusted, it may affect the overall braking force. Loose or rusted connections in the brake pedal mechanism can also cause failure, especially in rainy or high-humidity environments. Neglecting brake pad thickness checks during maintenance is another issue—they should be replaced when worn below 3mm. Additionally, when the battery voltage is low, electronic power assistance fails, making the brakes stiff. It is recommended to focus on checking these points during every maintenance session.
