EBC S20K1307 S20 Ultimax Brake Pads and RK Rotors Kit Front and Rear

The EBC S20K1307 is a complete two-axle disc brake kit that pairs EBC Ultimax brake pads with EBC RK plain rotors for both the front and rear axles. Designed as a high-quality OEM-style upgrade, this kit delivers confident, quiet stopping performance for daily drivers including cars, trucks, and SUVs.

EBC Ultimax Brake Pads

The Ultimax pads are engineered with a blend of synthetic aramid fibers and metallic filament for extended pad life with minimal noise and vibration. Each pad is fully shimmed and chamfered, and features EBC's patented Brake-In coating for faster pad bedding after installation. Pre-fitted anti-noise shims and a centerline slot help keep braking noise to a minimum during the life of the pad. Backed by a 1-year / 10,000-mile warranty against factory defects.

EBC RK Series Brake Rotors

The RK rotors are a direct-fit OEM replacement built from high-quality gray iron with a higher carbon content to reduce brake shudder, heat cracking, and high-frequency vibration. A Geomet anti-rust surface coating protects against corrosion, and each rotor is fully balanced and runout-tested for smooth, vibration-free braking. EBC recommends a 500-mile break-in period with lighter braking applications to maximize rotor life.
