Front grooved brake discs (ECE R90 certified) are core auto spare parts for mainstream passenger cars and SUVs, bearing over 70% of the vehicle’s total braking load during daily driving, high-speed deceleration, or emergency stops. The radial grooved design (6–8 precision slots) efficiently expels brake dust, rainwater, and high-temperature gas, preventing pad glazing and thermal fade—critical for maintaining stable braking in extreme conditions. As a mandatory safety standard for light vehicles (implemented since 2016), ECE R90 certification ensures performance deviation ≤8% from OE parts, passing strict tests like thermal fatigue, geometric accuracy (thickness variation ≤0.05mm), and corrosion resistance. Our front grooved discs are compatible with most mainstream brands (e.g., VW, Honda, Toyota, BMW) and models (Golf, Civic, Corolla, 3 Series), integrating seamlessly with factory ABS/ESC systems to deliver reliable, compliant braking performance.

Brake Discs Core Features

ECE R90 Compliance: Meets EU and global safety standards, passing thermal cycle tests (-40°C to 300°C) and dynamic load verification, ensuring legal compliance for vehicle maintenance and repair.
Optimized Grooved Design: 6–8 radial slots enhance debris evacuation; paired with a ventilated vane structure (most models), heat dissipation efficiency is 30% higher than solid discs, reducing brake fade risk.
Premium Material & Coating: Adopts G3000 high-carbon cast iron (wear-resistant, high thermal conductivity) with zinc-nickel/Geomet anti-corrosion coating, passing 500-hour salt spray tests to resist road salt and moisture.
OE-Grade Compatibility: Precise dimensional machining (bolt hole pitch, disc thickness) matches OE specs, supporting direct bolt-on installation without modifying the original brake system.
NVH Optimization: Non-directional friction surface machining + built-in damping shims reduce braking noise to ≤38dB, maintaining cabin comfort.

Brake Discs Key Benefits

Safety Compliance: ECE R90 certification eliminates legal risks for repair shops and vehicle owners, meeting roadworthiness inspection requirements in Europe, Asia, and America.
Stable Braking Performance: Grooves and ventilation prevent fade during frequent urban stops or mountain downhill driving, shortening emergency stopping distance by 5–8% vs. standard solid discs.
Long Service Life: High-carbon cast iron resists wear (service life up to 60,000 km for daily use), while anti-corrosion coating reduces rust-related replacement costs.
All-Weather Adaptability: Grooves break water film in rainy conditions, maintaining friction coefficient stability—avoiding "brake delay" in wet weather.
Universal Application: Compatible with 80% of mainstream passenger cars/SUVs (covering MQB, TNGA, FAAR platforms), reducing inventory pressure for auto parts distributors.
