The brake system will operate as a vehicle that does not have antilock brakes. It is safe to drive as long as you are aware of this and allow for it when you are stopping. This may cause some longer stopping distances depending on road conditions.
Wheel speed sensor codes usually do not require a BPMV to be replaced. The BPMV is the brake pressure modulator valve. It has nothing to do with wheel speed sensors.
The EBCM is the electronic brake control module. It reads the wheel speed sensor input to adjust the BPMV solenoids to control the brakes if they lock up.
Usually the wheel speed sensor issues are due to the sensors them selfs, or the wiring from the sensor to the EBCM.
With out the diagnostic codes that were set and knowing what kind of testing was performed and the results of those test. I can not say why they would want to replace both components, unless they are making an educated guess, because the concern is not present while they are testing it.
If you have new information to this concern please let me know. You can ask follow up questions if needed.
