EBC Brakes S9KF1226 S9 Yellowstuff Brake Pad and USR Slotted Rotor Kit

The EBC Brakes S9KF1226 is a complete Stage 9 brake upgrade kit that pairs EBC's flagship Yellowstuff high-friction brake pads with USR sport slotted rotors and caliper lube — everything needed for a significant braking upgrade in a single package.

Yellowstuff brake pads carry an EBC GG friction rating and are engineered to deliver 30–40% improved stopping power compared to factory pads. They perform across a wide temperature range, making them well-suited for demanding daily driving, hauling, or towing applications. Each pad is fully shimmed, chamfered, and slotted, and features EBC's patented Brake-In™ coating for rapid pad seating and optimal initial performance without a lengthy bedding process.

The included USR (Ultimax Slotted Rotor) series rotors are precision-manufactured from gray iron to EBC's exacting specifications. Fine, narrow slots evacuate brake dust, heat, water, and friction gases for a consistent pad-to-rotor contact surface and cooler operating temperatures. The rotors feature a Thermic Black anti-corrosion coating for long-lasting rust resistance. Each rotor is fully balanced and run-out tested to ensure vibration-free braking from the first stop.

Key Features:

• GG-rated Yellowstuff high-friction brake pads for maximum stopping power
• Delivers up to 30–40% more braking force vs. OE factory pads
• Patented EBC Brake-In™ coating for fast, easy pad seating
• Pads are fully shimmed, chamfered, and slotted to reduce noise and improve performance
• USR sport slotted rotors machined from gray iron to EBC specifications
• Fine rotor slots reduce wind noise and efficiently clear heat, dust, and debris
• Thermic Black anti-corrosion coating protects rotors against rust
• All rotors fully balanced and run-out tested for smooth, vibration-free operation
• Includes caliper lubricant for a complete, ready-to-install kit
• Saves compared to purchasing pads and rotors separately

Installation Notes: The Thermic Black rotor coating does not need to be removed prior to installation — it will naturally wear away in the pad-swept area within the first 10–20 stops. Do not use brake cleaner or any other method to remove the coating, as doing so voids the EBC warranty. Always fit the same pad upgrade to both the front and rear axle when upgrading.
