I recall you can actually read in the module at what mileage the error was cleared/brakes were replaced.
So before you "assume" the pads are worn out, you need to fully understand that triggered the Brake Warning light.
I was just getting ready to leave on a 1500 mile trip and my Brake Warning came on, turned out after trying to tie a spare, good brake pad wear sensor up in the suspension and plug it in, the light still did not go out until I reset the light with software.
Turned out the wear sensor had not even touched the rotor once I got around to replacing the brakes.

I recently had a brake pad sensor failure with PLENTY of life left in the rear pads.
Once the sensor is replaced, you can reset the warning through the gauge cluster. You can also reset the calculated mileage warning through the cluster. No software needed.
If you try to reset the warning without replacing the sensor, it comes back immediately, but it will still let you try to reset it.
