Brake Pads
Brake pads are the most frequently replaced brake component, and upgrading from stock pads delivers immediate improvements in stopping distance, pedal feel, and fade resistance. From daily-driver ceramic pads to track-spec metallic compounds, there is a brake pad for every application. Popular ProductsTop brake pad brands include EBC Brakes, Hawk Performance, StopTech, and Akebono. Popular compound choices include ceramic pads for low dust and quiet operation, semi-metallic for improved bite, and full metallic for track use. What brake pad compound should I choose?Ceramic pads are best for street use, offering low dust, quiet operation, and good bite. Semi-metallic pads add more stopping power at the cost of more dust. Full metallic and racing compounds are reserved for track use where extreme heat resistance is needed. How do I know when brake pads need replacement?Most brake pads include a wear indicator that creates a squealing sound when pad thickness reaches the minimum limit. ...
