Vehicle Compatibility: Complete front and rear brake kit includes 2 front rotors, 2 rear rotors, 4 front brake pads, and 4 rear brake pads. The front rotor dia.: 12.9"/328 mm, and the rear rotor dia.: 12.2"/309 mm. Compatible with 2010-2015 Lexus RX350, 2010-2015 Lexus RX450H, 2014 Toyota Highlander (Excluding Hybrid Models), 2015-2019 Toyota Highlander, and 2011-2020 Toyota Sienna. Low Dust and Noise: The brake pads are primarily made of ceramic material, offering superior wear and fade resistance. These ceramic brake pads produce less dust during braking, and their chamfered design ensures a snug fit with the brake rotor, reducing noise. Quick Heat Dissipation: The slotted and drilled brake rotors feature superior heat dissipation. Cool quickly under heavy loads or during emergency braking, preventing water and dust accumulation. Made from heavy-duty and durable HT250 cast iron, they resist deformation and provide reliable performance in various road conditions. Rust and Corrosion Resistance: The surface of the brake disc is treated with high-quality galvanization to prevent corrosion, enhancing durability and aesthetics effectively. Strict Specification Control: Each brake replacement kit undergoes rigorous dynamic balancing, ensuring responsive and stable braking during high-speed driving or emergency stops. This reduces vibrations and wear, significantly improving braking performance.
