The PowerStop S4798 brake caliper set is engineered specifically for performance and reliability, designed to fit a variety of models including the 2004-2005 Buick Rainier CXL and CXL Plus, as well as several GMC, Chevrolet, Isuzu, and Saab vehicles. This pair of front red calipers with brackets offers a direct bolt-on replacement for the factory-installed calipers, ensuring a seamless fitment and enhanced braking performance. Manufactured by PowerStop, a trusted name in the brake industry known for its commitment to quality and innovation, these calipers provide both aesthetic appeal and functional superiority.
PowerStop brake calipers are produced in the company’s Chicago, IL facility, where each unit undergoes a meticulous remanufacturing process. This process includes electrostatic high-temperature red powder coating, which not only delivers a striking visual enhancement but also provides robust resistance against rust and corrosion. This coating significantly extends the service life of the calipers, maintaining their performance and appearance over time, even under demanding driving conditions.
Each caliper is subjected to 100% pressure testing to verify piston operation and to prevent any potential leaks, thereby ensuring maximum safety and reliability. This rigorous quality control guarantees that every caliper meets stringent industry standards before leaving the factory. The kit includes all necessary components for installation and optimal function, such as new pistons, seals, slide pins (when applicable), dust boots, bleeder screws, and stainless steel brake pad abutment clips. These parts are selected and assembled with precision to provide a smooth and dependable braking experience.
High-temperature EPDM rubber dust boots and premium silicone lubricant are incorporated into the design to enhance durability and operational smoothness. These materials are specifically chosen to withstand extreme temperatures and conditions, reducing wear and tear while maintaining consistent performance. The vibrant red finish not only adds a performance-oriented aesthetic but also makes the calipers stand out behind both stock and custom wheels, appealing to enthusiasts who value both form and function.
