Manufacturers of brake pads are gearing up to meet a first-in-the-nation Washington state law requiring they phase out the use of copper and other heavy metals.
Washington in 2010 banned the use of copper in brake pads as a way to prevent the metal from polluting waters and harming fish. When brakes wear down, they release copper shavings onto roads and are eventually washed into rivers, where state officials say it could harm marine life, especially salmon.

I have never heard anything about that from the Michigan DNR and they are pretty serious about water quality. Our salmon runs are much bigger than most of the few that are left in Washington State.
