Brake Rotor
A metal disc that provides a surface for the brake pads to clamp against.
The brake rotor, or disc, rotates with the wheel and converts kinetic energy into heat during braking. Made from cast iron or carbon-ceramic materials, it endures extreme friction and temperature changes. Warped or grooved rotors cause vibration and reduced braking efficiency. Machining or replacing rotors restores smooth operation. Slotted and drilled rotors improve cooling and debris removal. Regular inspection ensures consistent braking and longer pad life. Proper rotor maintenance enhances stopping performance and driving safety.
