Gotta test that "stuff" out too. Go drive rt side wheels through wet pavement - stand on brakes , go drive one side wheels through sand on side of road - stand on brakes , do a HEAVY PEDAL in the mud.
All the while your watching the ABS ( Low Traction ) Light come ON. Maybe someone ,outside your car observing your wheels for the typical "pulsed skid " ABS does to the wheels.
Did you do this ? If & when you do , and All's well - NOW you know your OK . OK
