Information

Important: Service agents must comply with all International, Federal, State, Provincial, and/or Local laws

applicable to the activities it performs under this bulletin, including but not limited to handling, deploying,

preparing, classifying, packaging, marking, labeling, and shipping dangerous goods. In the event of a

conflict between the procedures set forth in this bulletin and the laws that apply to your dealership, you

must follow those applicable laws.

The purpose of this bulletin is to review the copper free regulation, how it affects Camaro and the service strategy for

each brake model RPO. The states of Washington and California have passed legislation beginning the phase out

use of copper in brake pads. Phase out dates limit copper content to < 5% by weight in 2021, and < 0.5% (essentially zero) by 2025. This is an effort to reduce metal content in storm water runoff negatively impacting the

environment in key watersheds.

Copper free legislation for California and Washington State is effective for all vehicles built on or after January 1,

2021. While this legislation affects all vehicle manufacturers and vehicle lines, the rollout for Camaro is complex. The

Camaro offers 7 different brake RPOs dependent on model. We will review the changes made, based on brake

RPO, to meet the Copper Free legislation. The brake service options will be categorized by vehicle RPO codes as

Frequently Asked Questions

Question: How are brakes serviced in California and Washington State on Camaro models produced prior to

January 1, 2021?

The Copper Free legislation does not affect the sale or serviceability of Camaro models built prior to January 1,

2021.
Question: Can dealers in CA & WA state service non-compliant brake components on Camaro models built on/after

January 1, 2021?

No – service parts needed to service brake components on Camaro models not compliant with the Copper Free

legislation are restricted from being ordered by dealers in California and Washington State.
Question: Are vehicles built after January 1, 2021 that don’t meet the copper free regulation prohibited from sale in

California and Washington State?

Although General Motors will restrict dealers in CA & Washington State from ordering Camaro models built on/after

January 1, 2021, there is nothing in place preventing the registration of non-compliant models in these states. There

is nothing in place to prevent a dealer from dealer trading for a non-compliant vehicle from a neighboring state and

selling it to a customer. The customer will not be aware of the non-compliance issue, until they need to perform a

brake service on the vehicle and are unable to obtain parts. In such cases, the customer should work with the selling

dealer to cover the cost of upgrading the vehicle to make it compliant to the Copper Free legislation. In this scenario,

the responsibility to upgrade the vehicle brake system to be compliant with the legislation, is not the responsibility of

General Motors.
Question: How does the California & Washington State copper free regulation affect the other 48 states?
Bulletin No.: 20-NA-229
August, 2024
Page 7
Although the initial legislation was adopted by California and Washington State, this was followed by a Memorandum

of Understanding backing the legislation by the US EPA, unifying the expectation for brake pads for all 50 states.

When servicing the different brake RPO’s found on Camaro model’s, it’s important for service technicians to understand whether they are servicing a vehicle with copper-containing linings or Copper Free components. Camaro HP

models (SS, ZL1), will offer copper free compliant brakes as an option for the remaining 48 states.
Question: Are dealers in California and Washington State prohibited from servicing Camaro models produced on/

after January 1, 2021 that are not compliant with the Copper Free Regulation?

Camaro brake pads not compliant with copper free legislation are restricted from being ordered by dealers in

California and Washington State.
Question: Starting in 2022 model year, how are Camaro HP models identified as copper free compliant?

The addition of RPO BCD will be added to the RPO string on the vehicle build record, indicating this vehicle would

originally be built to become compliant with Copper Free legislation.
Question: To make a Camaro compliant with the Copper Free legislation, is it just a matter of changing the brake

pads?

In order to maintain the same braking performance, the brake components have to grow in size and therefore, brake

pads compliant with copper free legislation will not fit on Camaro models with traditional copper-containing linings.
Question: Is it possible to make a vehicle produced with copper-containing linings compliant with the copper free

regulation?

To upgrade a Camaro model previously produced with copper-containing linings to be compliant with copper free

legislation, it will be necessary to replace, pads, rotors, calipers, brake shields and in most cases, a new EBCM

calibration will also be required. For Camaro models that offer components that are compliant to the new copper free

legislation, the cost to upgrade the brake system will range between $2,000 - $7,000, depending on model.
