A tip for those of you who live in areas that use a lot of road salt:
Those pins that hold the front brake pads in the calipers can rust in place so badly that you can't get them out. The only thing that works is "heat and beat" but heating with a torch will destroy the caliper seals. If your front brake pads last more than a year then I suggest that you replace those pins annually so you don't have to replace the calipers.
