Give your brakes a fresh surface to work against with the Beck/Arnley Brake Rotor 083-3778, a rear rotor designed to match OE form, fit and function. It fits many vehicles, among them the 2020-2026 Hyundai Sonata, 2024-2026 Hyundai Kona and 2025 Kia K4. See the "Vehicles it fits" section for the full list and engine details.
The rotor is the surface the brake pads clamp against to slow the wheel, turning the vehicle's motion into heat. Beck/Arnley designs this part as a direct replacement for the original, with attention to form, fit and function, and it is application specific to the listed vehicles.
- Matches OE form, fit and function: made to install like the original on the listed applications.
- Directional finish: designed to optimize break-in and pad seating.
- High carbon content: intended to maximize thermal conductivity.
- High-temp coating: applied to exposed surfaces to improve appearance.
Signs a rotor may need replacing include pulsation in the brake pedal, vibration while stopping, grinding noises, and scoring or deep grooves on the braking surface. Replacing both rear rotors together as a matched pair is recommended for even, balanced braking.
