Two problems related to brake fluid leak have been reported for the 1999 Ford F-150. The most recently reported issues are listed below.
The contact owns a 1999 Ford F-150. While driving approximately 45 mph, the contact depressed the brake pedal and noticed the brake pedal dropped to the floor board abnormally. The contact used the emergency brake and was able to stop the vehicle. The vehicle was not taken to the dealer for diagnostics. The contact inspected the vehicle and noticed brake fluid leaking from the brake lines as a result of corrosion of the brake lines. The vehicle was not repaired. The approximate failure mileage was 157,000. Updated 05/08/lj.
Fords recall of f150's for defective leaking cruise control cut-out switches does not totally fix the problem by them just adding an inline fuse for the fire problem. The pressure sensitive switch is screwed into the bottom of the brake master cylinder and even if the fuse blows disabling the cruise control by removing the 12 volts going to it the brake fluid can still leak out or be forced out by brake foot pedal pressure (which is very high) thru the defective switch seal onto the super heated exhaust system causing it to catch fire, and/or enough brake fluid to leak out causing air to be sucked into the master cylinder causing brake failure, and/or enough brake fluid to leak out causing brake failure. This is a "typical" Ford kludge repair to save money at people's lives expense. Paying lawsuits appears to be more cost effective in Fords eyes. They have pulled this crap for at least the 30+ years I can remember going back to the exploding Ford pinto's. My current 1999 Ford f150 is the last Ford I'll ever buy, period !!!.
