Description

PowerStop Brake Calipers are made specifically with the enthusiast in mind. These calipers bolt directly in place of the stock calipers, and they look and perform great behind stock or custom wheels. PowerStop calipers and the brackets are remanufactured in our Chicago, IL facility and treated with a electrostatic high-temperature red powder-coating. The easy to clean powder coating helps to resist rust and corrosion thus extending the life of your calipers. PowerStop calipers are 100% pressure tested to verify piston operation and prevent any possible leaks from occurring. This ensures that every caliper is inspected for quality and safety. PowerStop caliper pairs are expertly assembled using new seals, pad retainer pins and pin clips, dust boots, bleeder screws, and brake pad attachment hardware. High temperature EPDM rubber dust boots and premium silicone lubricant is used for a smoother operation and an extended life in extreme conditions. The color is a nice touch that really stands out behind your wheels!
