Chevrolet dealerships in California and Washington can no longer order a coupe or convertible 2021 Camaro SS, 2SS, ZL1 and ZL1 1LE.

These variants of the Chevrolet Camaro are equipped with brake pads that exceed the maximum amount of copper allowed in the two states, meaning they do not comply with their legislation. As such, customers cannot order an affected 2021 Camaro model for delivery after January 1, 2021, and dealerships will only be permitted to sell cars they currently have in stock.

“Due to restrictions in California and Washington state related to copper brake pads, customers in those states cannot order a 2021 Camaro SS, ZL1 and 1LE for delivery after January 1, 2021,” Chevrolet spokesman Kevin M. Kelly told GM Authority. “Customers can, however, purchase these models from available dealer stock in those states.”

It is believed that the issue relates to Camaro SS, ZL1 and 1LE models with the upgraded Brembo brakes, although this hasn’t been confirmed by the car manufacturer. Fortunately, Chevrolet is looking to rectify the issue.

“We will resume allowing customers in California and Washington state to order the Camaro SS, ZL1 and 1LE models in 2022 when we introduce a new brake system that is compliant with the copper requirements,” Kelly added.

As noted by The Drive, California and Washington introduced legislation in 2010 and 2011 respectively to limit the amount of copper that can be used in brake pads. These two bills require that no more than 0.5 per cent of the material used in the brake pads is copper by 2025, and for 2021, the Brembo brake pads are said to exceed the permitted amount.
