## What is wrong

ON CERTAIN VEHICLES, THE ELECTRONIC MONITORING SYSTEM OF THE SENSOTRONIC  BRAKE CONTROL \(SBC\) IS DESIGNED TO MONITOR THE PRESSURE GRADIENT WITHIN THE HIGH PRESSURE LINE OF THE BRAKE SYSTEM.  IF AN UNACCEPTABLE PRESSURE GRADIENT IS DETECTED, THE SYSTEM WILL SWITCH, AS IT IS DESIGNED TO DO, INTO THE HYDRAULIC FUNCTION MODE.


## What can happen

IF VEHICLES ARE NOT ROUTINELY SERVICED AND HAVE EXTREMELY HIGH MILEAGE COMBINED WITH A HIGH NUMBER OF BRAKE ACTUATIONS, OR A HIGH BRAKE ACTUATION FREQUENCY, THE PUMP MOTOR OF THE SBC MAY RUN OUT OF PERMISSIBLE TOLERANCES, THEREBY TRIGGERING THE HYDRAULIC FUNCTION MODE.


## The remedy

DEALERS WILL INSPECT THE SBC HYDRAULIC UNIT, REPLACING IT IF NECESSARY.  THE RECALL BEGAN ON OCTOBER 21M 2004.  OWNERS SHOULD CONTACT MERCEDES\-BENZ AT 1\-800\-367\-6372.
