EBC S9 Brake Pad and Rotor Kit

If you're looking to step up the braking performance on your 2015-2021 Hyundai Sonata, this EBC S9 Brake Pad and Rotor Kit is a solid option. It bundles together EBC's popular Yellowstuff high-friction pads with their USR slotted rotors, giving you a complete rear brake upgrade. The Yellowstuff pads are known for their strong initial bite and consistent performance, making them great for spirited street driving and even occasional track use. The USR rotors feature a fine slot pattern that helps keep the pads clean and cool, improving braking effectiveness, especially under harder use. This kit is designed to be a direct replacement for your stock rear brake components.

EBC puts a lot of thought into their kits. These USR rotors are made from G3000 iron and treated with a Geomet anti-rust coating, which helps them resist corrosion and maintain a clean appearance longer than plain rotors. They're also balanced and tested for run-out to ensure smooth operation. The Yellowstuff pads come with EBC's patented Brake-in coating, which helps seat the pads to the rotors quickly and efficiently for improved performance right from the start. This kit offers a noticeable improvement over stock, providing more confident stopping power.

This kit covers the rear brakes for your Sonata. Remember to check your vehicle's specific bolt hole count and rotor diameter to ensure this is the correct fitment for your application. If you're doing a full brake job, you might also want to consider replacing your brake fluid and inspecting your brake lines.
