Commercial Vehicle Rear Brake Disc ECE R90 Auto Spare Parts

Brake Discs Features:                                                   

•Ventilated brake discs represent the premium standard for front-wheel braking systems in modern vehicles.

•Their distinctive double-layer hollow configuration, integrated with internal cooling fins, efficiently dissipates the substantial heat generated during braking operations.

•Low noise

• This sophisticated design delivers exceptional stability under sustained braking conditions and superior resistance to thermal fade, thereby ensuring reliable performance during long-distance travel or frequent braking events—while achieving an optimal balance between high performance, extended service life, and practicality for daily driving.

Sporty Driving/Track Use

For high-performance vehicles or track driving, drilled & ventilated or slotted & ventilated discs are preferred. Their exceptional heat dissipation significantly reduces heat fade, maintaining braking efficiency under demanding conditions. The drilled design also helps expel gases and debris from the brake pads, ensuring optimal contact between the pad and disc under extreme conditions.

“ECE R90-compliant commercial vehicle rear brake discs” are high-reliability components specifically engineered to meet the demanding requirements of commercial operations.

Compared to passenger vehicles, commercial vehicle braking systems have fundamentally different priorities regarding durability, reliability, and total cost of ownership.

The core value of this brake disc lies in its specialized optimization for commercial vehicles' high-load, high-frequency, and long-cycle operation characteristics, while ensuring the highest safety standards (ECE R90). It aims to maximize vehicle uptime and reduce total cost of ownership.

Reinforced Design for Commercial Applications (Core Advantages)

1. Exceptional Wear Resistance and Extended Lifespan: Constructed from high-carbon cast iron with specialized heat treatment, it delivers superior hardness and abrasion resistance. This enables it to withstand frequent braking and impacts from greater inertia, significantly extending replacement intervals and reducing vehicle downtime for maintenance.

2. Robust Structure and Deformation Resistance: Commercial vehicles carry heavier loads and endure higher braking forces. This brake disc features reinforced ribs and structural design to enhance overall rigidity, effectively resisting thermal stress and physical deformation during sustained braking. This prevents brake shudder and ensures smooth, consistent stopping power.

3. Stable Braking Performance:

Delivers outstanding resistance to thermal fade. Maintains reliable braking force even under prolonged high-temperature conditions, such as extended downhill descents, ensuring vehicle safety.
