From time to time, manufacturers issue a recall due to some problems signalled by the customers. This is normal and it recently happened to Ford, who issued a recall for selected 2014-2017 Ford F-150 units equipped with 3.5-liter EcoBoost engine.
In affected vehicles, the brake master cylinder may allow brake fluid to leak from the brake master cylinder front-wheel circuit into the brake booster.
Depending on the amount of brake fluid loss from the brake master cylinder front-wheel circuit into the brake booster, the driver will receive an audible chime, message-center alert, red brake warning indicator in the instrument cluster, and/or may begin to experience a change in brake pedal travel and feel, including increased pedal effort. If a loss of brake fluid is substantial enough to reduce brake function to the front wheels, full braking function will remain in the rear wheel circuit. However, reduced brake function in the front wheels can extend stopping distance, increasing the risk of a crash.
Ford is aware of seven low-speed/low-impact accident allegations with two injuries associated with this issue.
This action affects 292,311 vehicles in the United States and federal territories, 43,536 in Canada and 8,053 in Mexico.
Dealers will replace the brake master cylinder and, if it is leaking, the brake booster will also be replaced. The Ford reference number for this recall is 20S31.
