Description Under the Better Brakes Law, Chapter 70A.340 Revised Code of Washington (RCW), manufacturers of brake friction materials are required to report and certify brake friction materials offered for sale in Washington State. The law, passed in 2010, set out to reduce the use of toxic material in brake friction materials, and beginning in 2015, restricted the use of asbestos, cadmium, chromium(VI), lead, and mercury.

The law also established a two-tier provision to phase out copper in brake friction materials by 2025. The first tier, beginning January 1, 2021, restricts the selling or offer for sale of brake friction materials in Washington State manufactured after January 1, 2021 and containing more than 5% copper by weight.

This study will (1) identify manufacturers that have not yet certified their products for sale in Washington in compliance with the 2021 metals restrictions, and (2) verify the accuracy of reported data submitted under the Washington State brake self-certification program.

Metals analysis will be performed on drilled brake friction materials for total cadmium, copper, lead, mercury, antimony, nickel, and zinc. Testing for chromium(VI) will also be performed. Brake formulations may change as part of reducing the use of copper, so this study will also assess concentrations of antimony, nickel, and zinc.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
