Ford Motor Company (Ford) is recalling certain 2016-2017 Ford Expedition, Lincoln Navigator, and 2016-2018 F-150 vehicles equipped with 3.5L Ecoboost engines. The brake master cylinder may allow brake fluid to leak from the front wheel circuit into the brake booster.
A loss of brake fluid may result in a change in brake pedal travel, increased pedal effort and reduced front brake function, requiring greater effort and distance to stop the vehicle. These conditions can increase the risk of a crash.
Dealers will replace the brake master cylinder. If the master cylinder is leaking, the brake booster will also be replaced. Repairs will be performed free of charge.
