Front brake sensor

Hey guys,

I recently got the "replace front brake pads" message. Took off the wheel, brake pads have at least 50% left, and sensor isn't visibly tripped yet. I couldn't reset the service message either. Any ideas what could be causing this? I haven't had time to pull the sensor and measure continuity, but it looks brand new to me and has not made contact with the rotor yet.

You sure it's front?

Maybe it's for rear?

You sure it's even for pads?

Maybe it's for fluid

iDrive says replace front brake pads, also shows message: Front brake pads at minimum thickness.

Well the system is conditional based.

So if the pads are really old, it might lower the interval. Or if you brake aggressively, then it will lower the interval.

Did you check both sides? Maybe the side with the sensor was seized and the pads weren't really doing their job. Is the passenger side more worn down?

It could also be a faulty connection at the connector or maybe a wire was frayed.
