There is a sensor on each set of pads that will wear thru if you let the pads go to far. The sensors are cheap $12 or so. You might want to pull the wheels and see how many you need. They are essentially a wire so as long as they aren't cut through they will last the life of your car.

Epiq (a sponsor of this board) has some pretty good pricing on pads but since you are in Canada the shipping and duty from the states may make it cost prohibitive to buy them in the states. I have seen some Canadian distributors selling Zimmermans on eBay with good pricing. Run a search there and don.t forget to search eBay stores as well. A lot of vendors don't list everything for auction every week.

I tried Auto Zone and they didn't have anything in stock. It all had to be ordered and I found it would be cheaper to go online.
