Why is copper used in brake pads?
• A: Copper performs several functions: it adds structural integrity to the brake pad material, reduces fade so that brakes remain effective through extended braking events, transfers heat efficiently, and helps brakes be more effective in cold weather. Copper also has properties that help prevent brakes from squeaking and shuddering when they are used, which is very important for car customer satisfaction and keeping warranty costs low. Not all brake pads contain copper. Copper content varies from manufacturer to manufacturer and even among pads made by the same manufacturer, but brake pads for new cars and original equipment replacement pads are generally likely to have higher copper content than other replacement pads.
