Re: "To provide a better experience to customers"
If brakes are worn they should be replaced. Many cars provide a warning light for this purpose, although many of these only operate on one wheel.
One wheel should be fine so long as it's one that has a higher level of wear (so say 2 of your pads aren't already badly worn when the light comes on).
I've seen a system which had a wire embedded in the pads, and as they wore they'd eventually break the wire, which would cause the warning light to come on. It's a fairly simple design.
