Brake Light Keeps Tripping

[Mandi90TT]

I changed all my brake pads, and flushed the fluid about 6 months ago, and reset the brake pad sensors, as well.

however, now, about every 50-75 miles, the brake warning will pop up, and it will be the front brake pads. i can reset the warning light, and it won't come back on for another 50-75 miles.

i've checked the pads, they are still at almost full thickness (both front and rear). the rotors look fine, as well.

fluid is topped off.

brakes aren't giving me any issues; not squishy, not squealing, no loss of stopping power, nothing

These are the pads i am using. i have been using those pads ever since i got my M4 in late 2014, except when i take my car to the track, and i change them out for track pads, and then change back over after the track weekend is done.

changed out the rotors about two years ago, and they look fine.

any idea why the brake warning light might be happening?

By "reset the brake pad sensors, as well." do you mean you replaced them with new or you only did the software reset in dash? If you only did the software reset you need to physically replace the sensors too.

As Farkle pointed out, if you did not replace the sensor up front and it was "tripped" (the wire was broken cause your pads were too low or it just got damaged when you removed and reinstalled) this is the reason to the light keeps coming on.
