Thanks for the replies. Wouldn't a failing master cylinder have leakage and fluid loss? Or, could the fluid pass by the piston and not leak out?

Master cylinders can and do fail with BOTH the above scenarios. If after flushing/changing the brake fluid, you experience the pedal to the floor, . . . . again, your master cylinder may be due for replacement.
By NOT changing the brake fluid in a timely manner, you are encouraging ALL of the other wear item brake parts that are in contact with the brake fluid to wear/corrode more quickly due to water contamination.
