The rotors are crafted from high-quality cast iron with precision-machined slots to enhance pad bite and channel away dust and gases generated during braking. This design reduces brake fade and maintains consistent performance under demanding conditions. The kit’s components are engineered to fit precisely with the original parking brake hardware, ensuring reliable mechanical parking brake function without modification.
