ANTI-LOCK BRAKE UNIT LEAKING BRAKE FLUID. STARTED ABOUT 5/5/97. LEAKS WITH CAR PARKED, MAY LEAK WHILE DRIVING. STARTED GRADUALLY, NOW LOSES ABOUT TWO OUNCES PER WEEK. IF BRAKE FLUID LEVEL GETS TOO LOW WHILE DRIVING, IT CAN PREVENT PROPER BRAKE OPERATION AND INCREASE THE RISK OF ACCIDENT. THE ABS UNIT IS LOCATED NEAR THE ENGINE EXHAUST AND JUST AFT OF THE RIGHT FRONT WHEEL. I SUSPECT THAT BRAKE FLUID MAY DRIP ON THE HEATED EXHAUST SYSTEM; PERHAPS THIS COULD CAUSE A FIRE. IF DRIPPING BRAKE FLUID GOT ON THE TIRE, IT COULD REDUCE TRACTION AND CONTRIBUTE TO AN ACCIDENT. ALL OF THESE POSSIBILITIES COMPRISE SAFETY HAZARDS. IN ADDITION, I HAVE CHECKED MULTIPLE SOURCES FOR USED ABS UNITS AND ALL ORIGINAL UNITS LOCATED ALSO LEAK. THIS IS APPARENTLY A COMMON PROBLEM. SOME OWNERS HAVE REMOVED AND BYPASSED THE ABS UNIT TO STOP THE LEAK. THIS IS PROBABLY ALSO UNSAFE. I SUGGEST THAT THE MANUFACTURER SHOULD REPLACE ALL SUCH DEFECTIVE ABS UNITS AS A SAFETY MEASURE.
