Fluid leak could affect front brake performance.

Ford will recall more than a quarter-million units of its best-selling F-150 pickup truck due to a potential brake problem. In the 2013-2014 Ford F-150, a defect with the brake master cylinder could allow brake fluid to leak from the master cylinder into the brake booster.

The problem affects only 2013-2014 Ford F-150 trucks equipped with the 3.5-liter EcoBoost V6 engine, and only affects the front braking circuit, so the truck’s rear brakes would remain effective. Ford says it is aware of nine accidents due to the problem, though none of those involved injuries, as well as another injury related to the braking problem but “not associated with an accident.”

The National Highway Transportation Safety Administration, meanwhile, said in February 2016 that it had received 33 reports of master-cylinder failures in the 2013 and 2014 F-150, of which four were said to involve accidents. In those instances, owners reported to NHTSA that the brake pedal suddenly went to the floor because fluid had leaked.

Ford says it will replace the brake master cylinder in all affected vehicles, and will also replace the brake booster if there’s evidence that brake fluid leaked into the booster. The recall affects a total of 270,873 F-150s worldwide, of which 225,012 are in the U.S., 43,682 are in Canada, and 402 were sold in Mexico.

Ford issues safety recall for certain 2013-2014 Ford F-150 vehicles in North America to replace their brake master cylinders.
Ford is issuing a safety recall for approximately 271,000 2013-2014 Ford F-150 vehicles to replace brake master cylinders. In some vehicles, it is possible brake effectiveness could be reduced due to brake fluid leaking from the brake master cylinder into the brake booster, increasing the risk of a crash. The brake fluid leak affects brakes to the front wheels only and does not affect rear wheel braking.

Ford is aware of allegations of nine accidents with no injuries, and one alleged injury involving interaction with the vehicle’s brakes but not associated with an accident.

Affected vehicles include certain 2013-2014 Ford F-150 vehicles equipped with 3.5-liter GTDI engines built at Dearborn Truck Plant, Aug. 1, 2013 through Aug. 22, 2014; and Kansas City Assembly Plant, Aug. 1, 2013 through Aug. 31, 2014. There are 270,873 vehicles affected including 225,012 in the United States and federalized territories, 43,682 in Canada and 402 in Mexico.

Dealers will replace the brake master cylinder at no cost to the customer. Additionally, dealers will replace the brake booster if they find leaks from the brake master cylinder.
