I could describe how the brake pad light works but it would take some time. The short answer to your question is YES.

This is set up so you will have plenty of warning that your pads need replacing. In some parts of the world you may be 600 miles from the nearest dealer.

Make sure you order the brake pad warning wires when you order new brake pads. The dealers sell these cheap and they should always be replaced when you do the front brakes.

It is also possible that someone has replaced the brakes with pads that did not have holes for the warning wires and drilled their own so they are in the wrong place.
