1. Car was being driven at normal speed, approximately 30 mph, and brakes were applied. Brake pedal traveled further than normal and brake warning light illuminated. When I arrived home I opened the hood and saw the brake fluid level in the master cylinder had dropped significantly. On further inspection I saw brake fluid on the frame rail on the driver side of the car at a location under the driver side front door (approximately). 2. It appears that the rear brake line was rubbing on the car body/frame structure and wore through allowing the brake fluid to leak out. 3. No repairs have been done yet. I am still investigating my options: repair at my expense, file a claim with Ford, etc.

I purchased a pre-owned,low milage 1996 Grand Marquis Mercury LS[VIN#2melm75w2tx620859] from a local car dealer in January 2000. The car was in immaculate condition with only 57800 miles on the odometer. November,2003,while driving the car,I lost all braking. My local repair shop fixed the problem[brake line failure]. While at my state inspection in March,04,the brake line "blew" out again while the technician was testing the brakes. I feel this is a very serious saftey factor. I value my life and I feel there should be a re-call on this problem. So far,repair bills total over $500. This is a great automobile except for the brake problem I am experencing.
