My first thought is if you're driving normally, you aren't boiling fluid like you would on a road-racing course. But then I don't know how old & waterlogged your brake fluid is.
Here's the classic way to differentiate... but it doesn't count if you've gotten your brakes glowing red-hot.
Air in the system:
Spongy pedal when you first step on it. Pump a couple times & it comes back.
Failing master cylinder:
Hard pedal when you first step on it, especially if you brake hard. While holding the pedal with low-to-moderate pressure (long red light) the pedal will slowly & smoothly sink to the floor.
