If this happens, once the vacuum reserve is depleted drivers will no longer have power assist braking. They still will have foundation brake function, but with increased brake pedal effort –a scenario that most drivers will want to avoid. Ford is expected to begin the recall on or about July 7, 2008, but if you want to learn more, you can contact Ford at 1-800-392-3673.
Ford Recalling 605,684 F-150s and Lincoln Mark LTs over Brake Issues
More than 600,000 MY2005-2006 Ford F-150s and Lincoln Makr LTs equipped with 5.4L 3-Valve engines are being recalled due to a faulty brake booster vacuum supply hose. Over time, the hose that is attached to the intake manifold may swell and lose retention force, a condition that could allow the hose to become detached from the fitting during an intake manifold backfire.
