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.

Key Features & Multi-Domain Value

• Metallurgy & Thermal Engineering
  Forged from Gray Iron and High Carbon, conforming to G3000, GG15HC, DIN, and SAE standards. The high carbon matrix enhances thermal capacity, while the vented structure (shown in the main image) accelerates heat dissipation through internal cooling vanes. This effectively resists brake fade, judder, and thermal cracking during repeated heavy braking, ensuring a stable friction coefficient for both daily commuting and demanding driving.

• Precision Machining
  Every disc undergoes expert turning and grinding. Strict control over disc thickness variation (DTV) and lateral runout guarantees a perfectly flat friction surface. The result is the elimination of high-speed steering wheel vibration and abnormal braking noise, providing a refined, OEM-like driving experience.

• Anti-Corrosion & Aesthetics
  To withstand harsh global climates (coastal humidity, winter road salt), we offer four anti-rust solutions: oiled, painted, coated, and zinc dust. Available in gray, black, metal, and gold finishes, these protect the hub and non-friction areas from oxidation. Premium finishes (like gold/zinc dust) also add visual value for open-wheel aftermarket setups.

• Global Compliance
  Produced under IATF16949, ISO14001, and ISO45001 certified systems. The discs meet ECE R90 (European) and AMECA (North American) standards, ensuring seamless regulatory market access and batch traceability for international distributors.

• B2B Customization & Logistics
  We support private label and customized labeling to build your brand. Packaging options (box, carton, pallet, bulk) are designed for sea freight efficiency. The 4 listing images (including a dark-background stacked shot) and the uploaded MP4 video, combined with the platform's AI background removal tool, provide ready-to-use, high-converting media assets.

Application Range

Suitable for sedans, MPVs, SUVs, and light commercial vehicles. The vented design provides superior thermal performance for heavier vehicles and long-distance driving, while the anti-rust finishes allow adaptation to any global climate.

Installation & Bedding-in Guidance

Replace brake discs in axle pairs with compatible brake pads. Avoid sudden hard braking for the first 300 km. Perform repeated gentle to moderate stops to establish an even transfer layer between the pad and disc, minimizing noise and maximizing service life.

Storage & Transportation

Store in a dry, ventilated warehouse away from corrosives. For sea freight, use moisture-proof inner packaging and desiccants to protect oiled/coated surfaces from oxidation before installation.
