No matter what, if the abs system failed you will still have brakes just like everyone else. who’s cars doesn’t come with ABS…The ABS system is for when you who are in a skid situation…It prevents the tires from locking up and not being able to control the situation…ABS braking is only applied during abnormal braking ..such as in a skid position or during when tire looses surface contact.. If the brake pedal went to the floor then the master cylinder is bad…because if you pump the brakes then they feel fine.. If you hold the brake pedal and it continues to go to the floor then the m/cylinder is bad, not the ABS>>>If the mastercylinder fails, then the ABS will not function properly

Your co-worker was driving like an idiot, and is tring to blame it on the car to get out of trouble.

My opinion……
