Ford F-250 odometer stopped working after brake booster replacement on Ford F-250

Some Ford F-250 owners report experiencing odometer issues following a brake booster replacement, which may stem from various causes. These owners have noted that electrical problems could arise during the brake booster installation, potentially affecting the odometer's functionality. Additionally, some have found that replacing the Vehicle Speed Sensor (VSS) in the rear axle may resolve the issue, but if that doesn't work, checking the wiring to the sensor is recommended. Others have identified the ABS module as a possible culprit, advising the inspection of fuses under the dash, particularly fuse #8, as a blown fuse could disrupt both the speedometer and odometer. Furthermore, some owners have reported a squishy brake pedal, indicating air in the system or the need for rear brake adjustments, suggesting that bleeding the brake system might be necessary. While a malfunctioning brake booster could lead to reduced braking power, it typically does not stop the brakes from working entirely. If the odometer problem continues, it is advisable for owners to consult a qualified mechanic or Ford technician for a thorough diagnosis and resolution.
