Front 2 Piece Brake Rotor For Mercedes

A0004212012 is a high-performance two-piece floating split brake rotor designed for Mercedes-Benz high-performance models. Upgraded from traditional one-piece brake discs, this split rotor adopts G3000 high-carbon cast iron friction ring and lightweight aluminum center hat structure. It delivers better heat dissipation, higher thermal stability and longer service life for high-speed and frequent braking scenarios. All products are strictly manufactured under ISO9001 / TS16949 standards and come with a stable 80,000 KM global warranty. We support full OEM and ODM customization for worldwide importers, distributors and tuning shops.

All A0004212012 split brake rotors are produced with standardized automotive-grade processes to guarantee high precision, low vibration and ultra durability.

Raw Material Strict Inspection – Adopt qualified G3000 high-carbon cast iron and 6061 / 7075 aviation aluminum alloy. Each batch is tested for hardness, density and composition to ensure stable friction performance and anti-deformation ability.

High-Precision Casting & Forging – Integral casting and high-temperature forging improve material density, effectively avoiding crack and wear problems under frequent high-load braking.

5-Axis CNC Machining – All mounting holes, friction surfaces and assembly sizes are precisely processed with tolerance controlled within ±0.02mm, ensuring 100% perfect installation for Mercedes-Benz high-performance vehicles.

Floating Riveting Assembly – Adopt high-strength stainless steel rivets for floating connection. The split structure allows independent thermal expansion, eliminating thermal stress and disc warping.

High-Speed Dynamic Balance Calibration – Every rotor undergoes dynamic balance testing to avoid braking jitter, ensuring smooth and stable braking experience.

Full Anti-rust Electrophoresis – Uniform electrophoretic coating prevents oxidation and rust, suitable for coastal, rainy and cold regions.

Final Full Inspection – Strict size check, hardness test, surface inspection and assembly test before shipment to guarantee zero-defect delivery.

We provide complete OEM and ODM solutions for global brake rotor wholesalers and tuning brands.

Compared with traditional one-piece brake discs, our A0004212012 split floating rotor has obvious advantages for Mercedes-Benz high-performance driving:

■ Excellent Anti-Warp & Anti-Fade Performance
The floating structure separates the aluminum hat and cast iron ring, allowing independent thermal expansion under high temperature. It effectively solves brake fading, disc warping and steering wheel vibration during continuous heavy braking.

■ Lightweight Design & Better Handling
Aluminum center hat reduces unsprung weight, improving suspension response, shortening braking distance and optimizing high-speed stability for Mercedes-Benz sports driving.

■ Strong Heat Dissipation & 80,000 KM Long Service Life
Ventilated internal structure accelerates heat dissipation. High-carbon cast iron material improves wear resistance, supporting up to80,000 KM service life and greatly reducing after-sales rate.

■ Cost-Effective Maintenance
Modular split design allows only replacing the worn friction ring instead of the whole rotor, saving long-term maintenance cost for end users and repair shops.

■ Quiet & Stable Braking
Floating buffer structure reduces vibration transmission, avoiding abnormal braking noise and providing consistent smooth brake feeling.
