Brake Discs Features:                                                   

•Equivalent to OE design 

•Smooth and quick stop 

•Anti-rust 

•Low noise, low dust 

•Optimal thermal performance 

1. Vane Geometry Engineering: OE-Matching Airflow for Front Axle

Our vented front discs feature precision-cast internal vane geometry that replicates the original equipment airflow pattern, ensuring optimal cooling performance identical to factory-fitted discs. The directional vane design maximizes heat extraction during heavy braking, reducing operating temperatures by up to 20% and minimizing thermal cracking and brake fade on high-performance Mercedes-Benz and VW models.

2. ECE R90 Homologation: Legal Access to EU & UK Aftermarket

All front brake discs are fully ECE R90 type-approved, with friction performance validated from -40°C to 600°C through independent dynamometer testing per EU regulation 90. This homologation grants legal access for aftermarket distribution across all 27 EU member states and the UK, with full type-approval certificates and batch test documentation provided for every shipment.

3. Coating Technology: Anti-Corrosion for Long-Term Appearance

We offer three advanced coating technologies — oiled for basic storage protection, painted for OEM-matching appearance, and Geomet/Dacromet for superior long-term corrosion resistance — each applied after final machining to preserve dimensional accuracy. The Geomet coating provides up to 500 hours of salt spray resistance, preventing rust on non-friction surfaces and maintaining a clean, premium appearance on alloy-wheel-equipped vehicles.

4. Mixed-Load Container Flexibility: Optimized Shipping for Distributors

Winhere supports mixed-item container loading, allowing distributors to combine multiple part numbers, configurations, and even brake pad sets in a single shipment to optimize freight costs and inventory turnover. With standard lead times of 7-15 days for stock items and 30-45 days for custom coated orders from Qingdao Port, we provide the flexibility needed for just-in-time inventory across global markets.

Brake Pads Features:

•High performance 

•Long-life service 

•Anti-fade 

•Low noise, low dust 

•Environmental friendly

1. Friction Coefficient Tuning: Pedal Feel Matched to European Brands

Our front brake pads are friction-coefficient tuned to match the specific brake system calibration of Mercedes-Benz and Volkswagen models, delivering the firm, progressive pedal feel characteristic of premium European vehicles. The stable friction coefficient (μ 0.38-0.42) remains consistent from cold starts to 300°C, ensuring predictable response with no sudden grab or fade during spirited driving.

2. Backing Plate Quality: Anti-Corrosion Steel for Structural Integrity

Each brake pad features a high-tensile steel backing plate with electrophoretic coating (e-coating) that provides superior corrosion resistance, preventing rust formation that can cause pad rattling and uneven wear. The precision-stamped backing plate meets OE dimensional tolerances for abutment clips and caliper interface, ensuring proper pad seating and smooth, chatter-free sliding within the caliper bracket.

3. Wear Sensor Compatibility: Integrated Options for MB & VW Models

Our front brake pad catalog includes variants with integrated electronic wear sensor connectors for Mercedes-Benz and Volkswagen models equipped with brake pad wear indicator systems, ensuring direct plug-and-play compatibility with no wiring modification required. For models without electronic sensors, mechanical wear indicators are integrated into the pad design, providing audible warning when thickness reaches the minimum safe limit.

4. Bed-In Ready: Thermally Scorched for Immediate Performance

Every brake pad set undergoes a thermal scorching (burnishing) process that pre-heats the friction surface to stabilize the compound, eliminating the need for time-consuming bed-in procedures after installation. This process ensures immediate, consistent braking performance from the first stop, reduces initial noise and dust during break-in, and extends effective service life by preventing glazing in early use.
