Was driving and experienced complete brake failure, no warning, went to stop and had no brakes what so ever! the brake line going to the passenger side front caliper had completely rusted away under the middle of the vehicle between the passenger side front tire and the abs distribution box. I was always told that the brake systems were designed with a tandem master cylinder so that if an event like this happened you would still have 2 wheels that had brakes. This obviously is not the case as there was a complete loss of all 4 brakes. Luckily I was only doing 25 mph and there was no traffic where I was when this happened, it took a ways to get the vehicle stopped by applying the parking brake. I don't want to even think what would happen if I was on the freeway doing 70 mph and had to stop in an emergency and this happened, I would probably be dead and possibly someone else also. This needs to be addressed ASAP. Peoples lives are at serious risk here. I cannot understand why these brake lines would not be made out of 318 stainless steel, they would never corrode and this would possibly save lives. I am totally convinced that people have died from this happening. This is nothing new with Fords! my mechanic told me that he sees Ford vehicles all the time with rusted out brake lines and people that have experienced complete brake failure due to this.

I was reading in a magazine about Ford having a problem with the brake master cylinder failing, leaking into the booster, causing brake failure. This happened to me a few weeks ago. I first felt my brake pedal getting weak. Then I saw a warning light. I first thought maybe my emergency brake was applied?? it was not. Then I noticed I had very little brake?? what to do?? I decided to try to get back to my job, where we have a service department. I drove about 50 miles with no brakes!!! just took my time, being careful. About $800 later I'm on the road again!!!.

Stopping at a red light and brake pedal went almost to floor. Had vehicle checked by local Ford dealer and they could find nothing wrong. Vehicle brakes have to be pumped a couple of times every time they are used. Took it back to Ford dealer. They say it is master cylinder. Ordered one over a week ago. Ford supply is all out and has a national back order which makes it sound as if I am not the only one with the brake problem although I cannot find a recall on it. Dealer is attempting to find a master cylinder through another source.

This has been an issue since acquiring this vehicle. The brakes are very soft, they will pump up but when a quicker slow down or stop is needed an individual doesn't have a lot of time to remember that. There have been no injuries or crashes as of this date. Master cylinder was replaced on mechanic's advice however this did not improve this issue. As well the vehicle seems to need the lower ball joints wear out quickly. Also please note that each time it rains there is water coming in from somewhere on the top driver's side of the windshield and post. It drips from that hand grip down to light switch and into vent on driver's side as well. There have been times where there is an electrical smell which causes concern of a vehicle fire possibility.

This complaint involves the complete failure of all brake lines due to rust on my 1998 Ford Expedition. All lines have completely rusted through from the outside in only 12 years. The first line (from the master cylinder to the abs control) failed about a week ago, resulting in total loss of brakes. Fortunately I was on a country road about 2 blocks from home and was able to get it back home. After replacing that line ($70 for the part) I took it out for a test drive. The second time I hit the brakes they again failed! this time the line going to the rear failed. The truck is presently at a Ford dealer. They say all lines are rusted through and need to be replaced. Cost: $3000! I feel that brake lines should not rust out in only 12 years on a vehicle that has been garaged all it's life. I believe that Ford motor company has some liability in this issue. I can't be the only one with this problem. Thank you for your time and consideration in this issue.
