Typically, the coating is applied to the outermost edge of the brake disc, leaving the center portion uncoated. This design allows for better heat dissipation and improved braking performance, particularly under high-speed or high-temperature driving conditions.

The partial coating on these brake discs also helps to reduce noise and vibration during braking, resulting in a more comfortable and smooth driving experience. Additionally, the coating can help to prevent rust and corrosion, which can extend the life of the brake disc and improve overall braking performance.

Compared to fully coated brake discs, partial coated brake discs offer several advantages. They typically have a lower cost than fully coated discs, making them a cost-effective option for drivers who want improved braking performance without breaking the bank. Additionally, the partial coating design helps to minimize the risk of uneven wear and tear, which can improve the longevity of the brake disc.
