比亚迪元 后轮ABS传感器 3630300 制动防抱死专用

When BYD Yuan’s instrument cluster lights up ABS fault, or during hard braking the brake pedal feels spongy, stopping distance increases, or there are signs of rear-wheel lockup, this usually indicates the rear ABS sensor has aged or failed and cannot accurately transmit wheel speed signals. When functioning properly, this sensor monitors rear wheel speed in real time and transmits data to the ABS control unit to ensure precise braking force distribution during emergency braking, preventing wheel lock. This product OEM number 3630300, fits BYD Yuan all variants. Installation requires disconnecting the battery negative first, and cleaning metal shavings and oil from the sensor mounting hole. Ensure the sensor head-to-ring gap is even, and tighten mounting bolts to standard torque to avoid signal interference.
