2004 SL500 Red BRAKE Warning on Instrument Panel
 

Changed out the front brake pads on the 2004 SL500 this morning. All went fine. Now a Red Warning light is showing on the instrument panel. Its in the shape of a Stop Sign and reads STOP. Any suggestions to get this reset?

sensor?

not really sure. also replaced the sensor on the right front. Hope it is not a brake master cylinder. replaced front brake pads, sensor, checked the fluid levels before and after. no leaks. friend that helped also had a snapon scanner reset machine/tool and reset everything. no warnings on the instrument panel except for the big red STOP light that looks like a stop sign

wondering if the open recall from 2005 would still be honored at the dealer?

Recall Date

Component
SERVICE BRAKES, HYDRAULIC
SummaryON 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.

ConsequenceIF 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.


What Owners Should DoDEALERS 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.

did the problem start right after the brake job? if so, I'd re-check installation again. I mess up things from time to time. make sure the connections and wires are good.
