What is the big deal about copper?
Government research has confirmed that copper can form deposits around the sealing surfaces of ABS valves, which means your car may take longer to stop in a panic situation. Because copper is a precursor to corrosion, research confirms that at certain levels, copper in the brake fluid is the best indicator that the fluid’s corrosion inhibitors are losing their punch and major corrosion is just around the corner. Copper provides a verifiable means of determining brake fluid condition. Copper is often frequently used in the brake lines of a brake system. With oxidation, this is the primary source for copper in the brake fluid.
