This does sound like an ABS activation.
If when it does this then you come to a stop and release the brake pedal and it drives normal, again this is an ABS activation. Lastly the fact that this only happens in slippery conditions when an ABS event would be expected, sounds like this is normal.
The fact that this didn't start until after you had all new brakes up front could be due to the fact that you had to brake harder before to get the same reaction from the brakes that you no longer have to do. So if you are stepping on the brakes with the same force, you could be locking them up and the ABS comes on to keep you from skidding.
If you can go to a parking lot that is covered in snow, try braking very softly and see if they lock up. The fact that the brakes operate normally in all other times except in slippery wet conditions, tells us the brakes are working as they should. So if we can get the brakes to operate normally in slippery conditions by braking softly then we know it is most likely normal.
Does this make sense? Thanks
