My brake pedal goes all the way to the floor when I stop at a red light. It just started tonight. What could be the possible cause(s)?

A leak in one of the hydraulic circuits or internal leakage in the master cylinder. If there's an external leak the fluid level will go down in the reservoir and you'll see a puddle on the ground.
