Brake discs, or rotors, are vital components in a vehicle’s braking system, providing the necessary surface for brake pads to create friction and slow or stop the vehicle. They are constructed from robust materials such as cast iron or carbon-ceramic composites to endure high temperatures and effectively dissipate heat. Different types of brake discs, including solid, ventilated, and drilled or slotted designs, offer varying advantages in cooling and performance. Regular inspection and timely replacement of brake discs are crucial to maintain safe braking performance and prevent brake fade caused by overheating. Properly maintained brake discs contribute significantly to vehicle safety, responsiveness, and optimal braking distances on the road.
