❔❔ What is the material of the brake rotors and pads?. ❔❔ What is the purpose of the holes and lines on the brake rotors?. ✔️ Guide heat outward and cool brake rotors faster. ✔️ The damped cast iron material of rotors,with a stable 3.2% carbon content, resists deformation and maintains uniform hardness distribution, eliminating the risk of cracking during braking.
