TL* THE CONTACT OWNS A 2007 (NA) BMW 535I. WHILE REVERSING OUT OF A PARKING SPACE AT 4 MPH, THE BRAKE PEDAL WAS DEPRESSED AND FAILED TO ENGAGE. THE CONTACT APPLIED PRESSURE AND THE BRAKE PEDAL TRAVELED TO THE FLOOR WHEN IT FINALLY ENGAGED. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE CONTACT'S VEHICLE CRASHED INTO A PARKED VEHICLE. THERE WERE NO INJURIES. THE POLICE WERE NOTIFIED, BUT NO REPORT WAS FILED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, BUT WAS NOT DIAGNOSED, THE MECHANIC INFORMED THE CONTACT OF NHTSA CAMPAIGN NUMBER: 10V446000 (SERVICE BRAKES, HYDRAULIC).

ON DAYS WARMER THAN 85 DEGREES, THE BRAKE PEDAL BECOMES STIFF AND GREAT FORCE MUST BE APPLIED TO STOP THE VEHICLE. IF THE CAR IS PLACED IN NEUTRAL AND THE ENGINE IS REVVED, THE BRAKE PEDAL RETURNS TO NORMAL, BUT RETURNS TO THE SAME PROBLEM SHORTLY. THIS ISSUE APPEARS TO BE THE SAME ISSUE THAT BMW ISSUED A RECALL FOR ON E60 VEHICLES WITH V8 ENGINES.

I WAS DRIVING MY 2007 BMW 525I ON A CITY STREET AND WHEN I ATTEMPTED TO STOP AT A STOP SIGN THE BRAKES WERE NON EXISTENT. THE BRAKE PEDAL LOST ALL OF ITS PRESSURE AND WENT ALL THE WAY DOWN WITHOUT STOPPING THE VEHICLE. I COULD NOT STOP AT THE STOP SIGN AND THE ONLY WAY TO STOP WAS USING THE EMERGENCY BRAKE WHICH BARELY STOPPED THE VEHICLE. THE BRAKES WOULD NOT WORK SO I WAS UNABLE TO DRIVE THE VEHICLE. AFTER FURTHER INSPECTION UNDER MY HOOD, I FOUND A BROKEN BRAKE VACUUM HOSE WHICH BROKE APART AND THIS WAS THE CAUSE OF THE BRAKE SYSTEM FAILURE. I WAS VERY LUCKY NOT TO BE INJURED.

I WAS TRAVELING APPROXIMATELY 40 MPH ON A CITY CAUSEWAY. I WENT TO APPLY THE BRAKES FOR A RED LIGHT AND HAD NONE. THE PEDAL WAS VERY STIFF AND HAD NO HYDRAULIC ASSIST. I PUSHED THE PEDAL AS HARD AS I COULD AND DOWNSHIFTED, FINALLY STOPPING ABOUT 8 FEET INTO THE INTERSECTION. THE CAR ACTED FINE ALL MORNING UP TO THAT POINT. I HAD NO WARNING LIGHT OR ANYTHING TO ALERT ME TO THE FAILURE. I HAVE SINCE FOUND OUT THAT BMW ISSUED A RECALL FOR THIS VERY ISSUE ON THE V8 ENGINE BUT NOT FOR THE I6 ENGINE WHICH I HAVE. *TR
