Ford Fusion ABS pump replacement issue with unresolved air bleeding problem on Ford Fusion

Some Ford Fusion owners report experiencing unresolved air bleeding problems after ABS pump replacement, which can lead to serious braking issues. For instance, pulling both ABS fuses completely disables braking, making it unsafe to drive without ABS functionality. Additionally, some owners notice persistent low brake pedal pressure even after replacing the master cylinder, indicating ongoing problems. Sticking passenger side brakes during ABS engagement may occur, and this issue might not be resolved by simply flushing old brake fluid. Furthermore, a spongy brake pedal after ABS activation often necessitates thorough bleeding of all brakes and inspection of the master cylinder or ABS valve body. Lastly, the simultaneous illumination of ABS, TCS, and Brake lights, along with a "Service Traction Assist" message, may suggest the need for a new ABS module, as identified by some Ford dealers. It is crucial for owners to address these symptoms promptly to ensure safe vehicle operation.
