Rear 2 Piece Brake Rotor For Mercedes

A0004231712 is a high-performance two-piece floating split brake rotor specially developed for Mercedes-Benz high-performance models, including E43 AMG, E53 AMG, CLS450, CLS53 AMG and E450. Upgraded from traditional one-piece brake discs, this split rotor adopts premium G3000 high-carbon cast iron friction ring and optional 6061 / 7075 aviation aluminum center hat. It features outstanding heat dissipation, excellent thermal stability and ultra-long service life, perfectly adapting to high-speed driving and frequent heavy braking scenarios of Mercedes-Benz sports vehicles. All products are manufactured strictly in accordance with ISO9001 and TS16949 automotive quality standards, with a reliable 80,000 KM global warranty. We provide professional customized OEM and ODM services for global auto importers, wholesale distributors and tuning brands.

All A0004231712 Mercedes-Benz split brake rotors adopt standardized automotive-grade manufacturing procedures, fully complying with international automotive industry standards. Every production step is strictly controlled to ensure high precision, low vibration, excellent stability and long durability for high-performance vehicle use.

Raw Material Strict Inspection – Adopt high-purity qualified G3000 high-carbon cast iron for friction rings, and premium 6061 / 7075 aviation aluminum alloy for center hats. Each batch of raw materials undergoes strict hardness, density and composition testing to eliminate unqualified materials fundamentally and guarantee stable friction performance and anti-deformation capability.

High-Precision Casting & Forging – The friction ring is processed by integral precision casting and high-temperature forging technology, which effectively improves material density, enhances wear resistance and structural toughness, and avoids cracks and deformation under frequent high-load braking conditions.

5-Axis CNC Precision Machining – All mounting holes, assembly surfaces and friction surfaces are precisely machined by 5-axis CNC equipment with strict tolerance controlled within ±0.02mm, achieving 100% perfect fitting for original Mercedes-Benz vehicles without any modification.

High-Strength Floating Riveting Assembly – Adopt imported high-strength stainless steel rivets and constant-pressure automatic riveting technology. The professional floating split structure allows independent thermal expansion and contraction between the aluminum center hat and cast iron friction ring, completely eliminating thermal stress and disc warping.

High-Speed Dynamic Balance Calibration – Every finished brake rotor undergoes full high-speed dynamic balance testing and fine calibration to eliminate rotation deviation, effectively preventing braking jitter and vibration, ensuring smooth and stable braking experience.

Full-Body Electrophoretic Anti-rust Treatment – Uniform and dense electrophoretic anti-rust coating is applied on the whole rotor surface, providing excellent oxidation and corrosion resistance, adapting to harsh environments such as coastal humidity, rainy and snowy weather.

Final Strict Full Inspection – Before delivery, all products pass comprehensive inspections including size recheck, hardness test, surface defect detection, assembly test and friction performance test. Only qualified products can be packaged and shipped.

We provide one-stop professional OEM and ODM customized solutions for global Mercedes-Benz brake rotor wholesalers, tuning brands and auto trading companies.

Compared with traditional one-piece integral brake discs, our A0004231712 two-piece floating split brake rotor has comprehensive performance advantages for Mercedes-Benz high-performance models:

■ Superior Anti-Warp & Anti-Brake Fade Performance
The floating separation structure solves the defect of synchronous thermal expansion of integral discs. Under continuous high-temperature and heavy-load braking, the friction ring and aluminum hat expand independently without thermal stress accumulation, effectively avoiding disc warping, brake fading, steering wheel jitter and pedal vibration.

■ Lightweight & Optimized Driving Handling
The high-quality aviation aluminum center hat greatly reduces unsprung weight compared with original one-piece discs. It improves suspension response sensitivity, shortens braking distance, optimizes high-speed driving stability, and perfectly matches the sports performance of Mercedes-Benz AMG series models.

■ Efficient Heat Dissipation & 80,000 KM Ultra-Long Service Life
Adopt internal ventilated channel structure to accelerate air circulation and rapidly discharge braking heat. Combined with high-density G3000 high-carbon cast iron material with excellent wear resistance, the product supports a formal 80,000 kilometers warranty, effectively reducing after-sales return and complaint rates for wholesale customers.

■ Lower Long-Term Maintenance Costs
Modular split design realizes separated use of center hat and friction ring. When the friction ring reaches the wear limit, only the worn ring needs to be replaced instead of the whole rotor, greatly saving maintenance costs for end customers and auto repair shops, and improving your repeat order rate.

■ Quiet & Comfortable Braking Experience
The floating buffer structure isolates vibration transmission between the hub and friction ring, effectively eliminating abnormal braking noise during low-speed and high-speed braking, delivering consistent, smooth and quiet braking feeling.
