A hydraulic system (your brakes) needs to be closed to transmit pressure from one place to another.
If the caliper goes away, there is suddenly an open line, the brake fluid goes away and you have no brakes.
ABS is a computer control system that prevents the wheels from locking up in a panic stop and allows you to steer the car instead of just sliding.
and..... most cars today are equipped with ABS; so there's and ID10T light on the dashboard somwhere that says, "ABS", and will indicate that something is amiss within the normally "closed" system.
When that "ABS" light comes on, I usually start with the master cylinder to check for proper brake fluid level; then work my way to each caliper. Sometimes there is just air in the system; bleeding it will usually fix the problem. Further inspection will of course locate any "real" problem.
