Others may feel differently, but when/if my SBC system needs REPLACING you can bet I'll do more than stick a fresh set of brushes against the motor. Especially if I thought someone else might be driving it. There's quite a lot more to the system than a hydraulic pump.
That said, yes. The system needs to be reset via STAR. Plenty of reading on the subject in this forum.

Replace the entire SBC unit with a rebuild. Your wife and children's lives depend upon the proper operation of the brake system.
Look for the information listed below using STAR. These numbers are from my W211's last service; the numbers indicate I'm still good but need to monitor more often rather than waiting for the red stop sign of death to appear on the instrument cluster. I would bet your remaining pump life is zero. And there is a good chance that the pretensioning reservoir pressure is below nominal.
-Brake system actual values:
-Bremsenzaehler (brake system solenoid actuations IIRC) – 301,454
-Pump cycles – 11,224,600
-Estimated remaining pump life in % - 23.2% (DJ_GetPmpLD)
Get to the above values by this route:
-Control units/Chassis/SBC sensotronic brake control/Development data/Actuations/Complete index of Actuations
The pretensioning value will be found under actual values under SBC folder.
-Pretensioning pressure in reservoir – 73 Bar (72-102 optimal)
