Two problems related to power assist brake hoses, lines/piping, and fittings have been reported for the 1996 Mercury Grand Marquis. The most recently reported issues are listed below.
Rear brake failure. Rear brake lines rusted and sprung a leak losing all brake fluid and the brakes to be able to stop.
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.
