The issue has nothing to do with emissions.
SS and higher trims have copper brake pads as they go against restrictions.
Chevy will return for 2022 with a new braking system.
If you live in California or Washington and were planning to give yourself the gift of a brand-new 2021 Chevrolet Camaro SS, 2SS, ZL1, or 1LE package, you are unfortunately out of luck. Both states have restrictions on the use of copper brake pads meaning that these superb sports cars will not be available for sale for the 2021 model year.
GM Authority reached out to GM asking both for a confirmation and an explanation and got the following response: “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,” said Senior Manager, Chevrolet Cars and Crossover Communications at General Motors, Kevin M. Kelly, in an official statement. “Customers can, however, purchase these models from available dealer stock in those states.”
But, not all is lost. GM did also say that they will revise the Camaro’s braking system with one that is compliant with the states’ restrictions for the 2022 model year.
