Brake failure refers to the loss of braking effectiveness in a vehicle. Here is the relevant introduction: BYD Song Pro: The BYD Song Pro is a "Global Intelligent Large Five-Seat SUV" under the BYD brand, officially launched on July 11, 2019, and awarded the Best Debut New Car Award at the 2019 Shanghai Auto Show. The BYD Song Pro is available in three different drivetrain variants: fuel-powered (Song Pro Fuel), plug-in hybrid (Song Pro-DM), and pure electric (Song Pro-EV). Interior: It features a first-of-its-kind Golden Cabin + Wraparound Interior Design, creating an ultra-sensory intelligent driver's seat that provides an exclusive space for the driver. The center console tilts 7 degrees toward the driver, achieving the most ergonomic design angle for ease of use and effective glare prevention without compromising the front passenger's experience. It also introduces the BYD-Heart Intelligent Hub for the first time, integrating key function buttons around the gear shift lever for easy access.

I used to drive a Song Pro, and one time the brakes suddenly failed, which was terrifying. The reason might have been that the brake fluid had leaked out, possibly due to a cracked pipeline or aged sealing rings. Additionally, if the brake pads are worn thin, the braking force can be significantly reduced; if the vacuum booster pump fails, the pedal can become very hard. Electronic systems like ABS malfunctions can also affect braking, such as sensor issues leading to uneven braking force. I later learned that regular maintenance is crucial—generally, it's recommended to change the brake fluid every 2 years and inspect the brake pads every 50,000 kilometers. In short, brake failure isn't just about the car's inherent flaws; poor maintenance can easily lead to accidents. If you notice any symptoms, pull over immediately and call a professional—don't push your luck. Safety always comes first!

Recently, I've been researching the issue of brake failure in the Song Pro. Common causes include hydraulic system problems such as oil pump or master cylinder failure, leading to insufficient pressure; mechanical component wear like brake disc deformation can also weaken braking; or control unit failures such as ECU malfunctions, affecting overall response. You can routinely perform simple checks yourself, ensuring the fluid level is between min and max—if it's too low, be alert for oil leaks. If you notice the brakes feeling soft or delayed, don't wait for complete failure; slow down and pull over immediately. For repairs, it's more reliable to visit a 4S dealership for professional equipment diagnostics rather than DIY, as this concerns your life and others'. Remember, older vehicles are more prone to such failures, especially in humid weather which can corrode components—regular maintenance can prevent 99% of issues.

Brake failure is extremely dangerous, often caused by hydraulic leaks, air entering the pipelines, or component failures like a broken booster. If any abnormality is detected, stop and inspect immediately—safety should never be taken lightly.
