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?

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.

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.
