My car states rear brakes are due in 6k miles.

Is this based upon a longevity estimate or upon a sensor reporting actual remaining life?

The brakes are fine, but I’ve noticed a small drop in performance recently; need to press the pedal down further to come to a complete stop and need to hold it there to not roll.

The car’s been through four summer’s already, during which I’ve never noticed same, but could this be weather / temperature related?

Thank you!
