When the brake pedal sinks further than normal or feels spongy, something is wrong in the hydraulic system that actually stops the car. This is one of the few symptoms that justifies not driving until it's checked.
Check the brake fluid reservoir — if it's low or empty, don't drive; have the car towed or a mobile mechanic come to it. A spongy pedal can become no pedal without much warning.

Topping up may restore some pedal temporarily, but fluid doesn't get consumed — if it's low, it went somewhere, and the leak still needs finding.
Because it means reduced hydraulic pressure — in a hard stop you may not have the braking force you expect.
Anywhere from a brake fluid flush and bleed to replacing a leaking component; diagnosis pins it down quickly.
