E-car oem grooved Brake Discs

This is a high-performance component engineered specifically for the unique demands of electric vehicles.

“Electric vehicles,” “OEM-matched,” and “grooved” are three key messages that collectively define this product's core value.

Electric vehicle battery packs significantly increase weight compared to comparable gasoline-powered vehicles, while electric motors deliver maximum torque instantly. This places higher demands on the braking system. The structure and material of this brake disc (typically high-carbon alloy cast iron) are reinforced to handle greater inertial forces and braking loads, delivering superior stopping power.

Corrosion resistance is particularly critical: Electric vehicles extensively utilize regenerative braking systems for deceleration, drastically reducing the frequency of traditional friction brake engagement. This leads to brake discs being more susceptible to rust formation due to prolonged inactivity. Grooved designs effectively scrape away rust and debris from the brake pad surface. This ensures that when critical braking occurs—such as during emergency stops—the pads immediately contact a clean friction surface, restoring optimal braking performance. This capability is vital for safety.

Enhanced Braking Efficiency: Radial grooves on the disc surface effectively cut through and expel vaporized and adhered substances generated between the brake pad and disc due to high temperatures. This ensures the brake pad maintains optimal contact with the disc surface, delivering more direct and stable braking force.

Enhanced Heat Dissipation and Cleaning: The grooves increase the heat dissipation surface area, aiding in heat transfer. Simultaneously, they act like scrapers, continuously cleaning the pad surface to prevent debris and dust buildup, maintaining optimal operating conditions.

Improved Wet Braking Performance: During rainy conditions, the grooves help quickly scrape away water films from the disc surface, reducing brake response time.

Perfect Compatibility: Designed as original equipment, these pads match your electric vehicle 100% in size, balance, and performance—installing without any modifications.
