Total brake failure, 2005 F-150 supercrew, king ranch 4x4 occurred in traffic on 11 Nov 2005, at a speed 34 mph. When I pressed the brake pedal, there were no brakes. My would have wrecked the vehicle, had she been driving, she was hysterical when the brakes failed. I used the emergency brake and down shifted to slow the vehicle. I didn't hit the vehicle in front of me, I managed to get the vehicle to the side road parking lot. There was absolutely no indication prior to this failure. It appeared I had lost the vacuum booster assist on my vehicle. The vehicle was towed to beale pkwy Lincoln Mercury for repair as it is under factory warranty. The service advisor called and told me my vehicle was ready late on the 12th. I went to the dealership to pickup my vehicle and talked with the mechanic that repaired it. I asked him what he did and he told me he reconnected a vacuum hose to the back of the manifold and stated it had blown off. I ask how did you secure it. He told me by pushing it back onto the port it came off of. I ask him why not install a clamp to keep this from recurring. He stated he would have to remove the manifold to accomplish a clamp installation. Beale Lincoln Mercury repaired my vehicle the best they could under the circumstances. I feel the mechanic should have installed something to secure the hose so this doesn't happen again, but he stated he didn't think Ford would pay for removing the manifold to install a clamp. I think Ford would much rather pay for a manifold r & r instead of a law suit from an accident, especially one with injuries or deaths due to a faulty design that renders the brakes useless. This has occurred on many other F-150's, some with accidents involved. Check the internet for F-150 brake failures. Ford needs to address the brake failure on the F-150's with 5. 4l engines before there is more damage or serious injuries. This should be an immediate recall by Ford. I am now uneasy driving this vehicle.
