DEARBORN, Mich. – Ford Motor Company has instituted a recall of nearly 200,000 Ford F-150 pickup trucks as well as Ford Expedition and Lincoln Navigator large sport utility vehicles due to a brake-fluid leak.

Certain model-year 2016-2018 F-150 (90.010), 2016-2017 Ford Expedition (90,055) and 2016-2017 Lincoln Navigator (15,499) equipped with the 3.5-liter Ecoboost engines might have a master cylinder breach which might allow brake fluid to leak from the front-wheel circuit into the brake booster.

According to the National Highway Traffic Safety Administration Part 573 Safety Recall Report 22V-150, “If a loss of brake fluid is substantial enough to reduce brake function to the front wheels, full braking function would remain in the rear wheel circuit. However, reduced brake function in the front wheels can extend stopping distance, increasing the risk of a crash.”

The cause of the problem, according to NHTSA, is contamination of the “brake fluid contamination that could interfere with rear cup seal function or, to a lesser exent, rolling of the rearmost cup seal in the master cylinder.”

The remedy will consist of owners taking their vehicles to a franchised dealer to have the master cylinder replaced and, if the master cylinder upon inspection is determined to be leaking, to also replace the brake booster.

Franchised Ford and Lincoln dealers were notified about the recall earlier this month, while owners are scheduled to be notified beginning April 25th.
