Rear Coated Brake Disc for MERCEDES-BENZ ECE R90

Brake Discs Features:                                                   

Drilled and ventilated brake discs represent a significant evolution in high-performance braking systems. The incorporation of strategically engineered holes serves a dual purpose: it functions as a critical thermal management mechanism and contributes to a distinctive, high-performance aesthetic.

The primary operational advantage lies in the discs' enhanced capacity to dissipate the immense heat generated during aggressive deceleration, thereby effectively mitigating thermal fade and preserving braking integrity under repeated heavy use. Concurrently, the drilled pattern actively evacuates water, gases, and brake pad debris from the friction interface. This ensures consistent and optimal pad-to-disc contact, delivering precise and powerful braking response. This combination of superior cooling and maintained friction makes them an essential upgrade for discerning enthusiasts who demand peak braking performance coupled with sporty visual cues.

Sporty Driving/Track Use

In the context of high-performance track use, ventilated brake discs with either drilled or slotted designs are strongly recommended. Their primary advantage lies in superior heat dissipation, which is critical for mitigating thermal fade and preserving braking power during demanding sessions. Additionally, the surface patterns (holes or slots) serve to evacuate gases and pad debris, guaranteeing optimal pad-to-rotor contact and reliable performance at the limits.

1. Mercedes Rear Coverage: C-Class, E-Class, S-Class, GLC & GLE

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

2. Advanced Coating Protection: Anti-Corrosion for Long-Term Appearance

These Mercedes rear brake discs feature advanced anti-corrosion coating technology (Geomet/Dacromet) that provides superior rust protection on non-friction surfaces, maintaining a clean, factory-original appearance visible through Mercedes' alloy wheels — eliminating the unsightly rust rings common on standard uncoated rear discs. The coating resists corrosion in winter-salt and coastal environments, extends disc service life, and preserves the premium aesthetic of Mercedes luxury vehicles.

3. Rear Axle Optimized: Consistent Braking for 30-40% Load Distribution

Engineered specifically for rear axle applications, these coated brake discs are optimized for the 30-40% braking force distribution typical of rear brakes — providing consistent, predictable rear braking performance that complements the front brakes for balanced vehicle stopping. The rear axle optimization accounts for the lower thermal loads and different duty cycle of rear brakes, ensuring optimal friction characteristics and wear patterns for extended service life on Mercedes vehicles.

4. ECE R90 Certified: European Safety Standard for Global Distribution

These Mercedes rear coated brake discs are ECE R90 certified, meeting the strict European Union safety standards for brake system components — ensuring consistent quality, performance, and reliability for global distribution including Europe, Middle East, Asia, and other markets requiring ECE certification. The certification includes rigorous testing for friction coefficient, wear resistance, thermal stability, and dimensional accuracy, providing customers with confidence in the product's safety and performance for Mercedes vehicles.
