Ford is recalling 605,684 2005-2006 model year F-150 and derivative Lincoln Mark LT vehicles equipped with 5.4-litre three-valve V8 engines to check a brake system hose.

According to the National Highway and Traffic Safety Administration (NHTSA) website, the brake booster vacuum supply hose attached to the intake manifold fitting may swell over time and become detached during an intake manifold backfire, leading to eventual loss of brake boost.

Dealers will replace the hose in the recall expected to begin around 7 July 2008.
