Back in 2010, California and Washington enacted laws declaring that beginning in 2021, the brake pads sold in their respective states couldn’t have more than 5 percent copper by weight. By 2025, the brakes had to have less than 0.5 percent copper by weight. It’s because of this rule that starting on January 1, Chevrolet won’t be able to sell the 2021 Camaro SS, 1LE, and ZL1 in those states due to the copper content of the Brembo brakes, which exceeds 5 percent.
Sales for those versions of the Camaro will resume in California and Washington for the 2022 model year once the brakes are replaced, a Chevrolet spokesperson told C/D. And, since the law goes into effect beginning on January 1 of next year, 2021 models that are currently in dealer inventory can still be sold in the new year.
The Chevy spokesperson wouldn’t clarify why the brakes weren’t replaced in advance for the 2021 model year, rather than the 2022 model year. The states gave automakers and other brake pad manufacturers ten years to find new technologies and replace the brake pads with high levels of copper content.
The copper from the brake pads, it was found, turns to dust and finds its way into waterways. Once it’s there, it becomes toxic to many water-dwelling creatures, including fish, plants, and amphibians. The copper is used in the brake pads because it’s able to quickly and effectively dissipate heat and allow for smooth braking.
