Mercedes Composite Grooved Brake Discs

Brake Disc Features:                                                   

•Equivalent to OE design 

•Smooth and quick stop 

•Anti-rust 

•Low noise, low dust 

•Optimal thermal performance 

•Composite design increases resistance to heat-induced warping and cracking. Grooves on the friction surface help dissipate heat and gas for more stable performance.

•Two-part design (steel center + cast iron ring) reduces weight by 10-15% versus traditional discs. Lowers unsprung mass for better handling, ride comfort, and improved fuel economy

•Grooves clean the brake pad surface and maintain effective friction contact. Results in a more consistent brake pedal feel and responsive braking

1. Mercedes Performance Lineup: C-Class, E-Class, S-Class, GLE & GLC

Our catalog covers the full Mercedes performance lineup including C-Class, E-Class, S-Class, GLE, GLC, GLA, CLA, GLB, GLS, and AMG models — ensuring the correct composite grooved brake disc for every popular Mercedes vehicle. Each part number is cross-referenced against Mercedes OE numbers for guaranteed fitment.

2. Composite Two-Piece Construction: Aluminum Hat & Cast Iron Ring

These Mercedes composite brake discs feature a two-piece construction with a lightweight aluminum alloy hat bonded to a high-carbon cast iron friction ring — reducing overall disc weight by up to 25% compared to traditional all-cast-iron discs. The composite design allows thermal expansion without warping, improves heat dissipation, and reduces unsprung mass.

3. Grooved Friction Surface: Enhanced Pad Bite & Gas Evacuation

These Mercedes brake discs feature precision-machined grooves across the friction surface that enhance pad bite, evacuate brake gas and water from the pad-disc interface, and improve initial bite in wet conditions — ideal for Mercedes performance and AMG models. The grooved design also provides a sporty appearance visible through Mercedes' alloy wheels, reduces brake fade, and maintains consistent friction coefficient.

4. High-Performance Vented Design: Optimized Cooling for Mercedes

Engineered for Mercedes' high-performance applications, these vented composite grooved discs feature optimized internal vane geometry that maximizes airflow and heat dissipation, reducing operating temperatures by up to 20% during aggressive driving — critical for AMG and performance models. The high-carbon cast iron friction ring provides superior thermal conductivity and resistance to brake fade and thermal cracking, while the aluminum hat further enhances heat dissipation.
