ECE R90-certified for safety, they outperform generic discs by 40% in wear resistance (tested to 100,000+ km). Trusted by global auto repair networks, their OEM-spec fitment guarantees hassle-free installation—offering a durable, cost-effective upgrade to elevate your vehicle’s brake reliability.
Product Advantage
1. Premium Cast Iron & Heat Resistance Engineering
Crafted from high-grade gray cast iron—backed by our 15+ years of brake system R&D—our discs feature advanced heat treatment to cut thermal deformation by up to 30% vs. generic alternatives. This prevents warping during heavy braking, ensuring consistent pad contact for reliable stopping power. Trusted by global aftermarket distributors, this material is the backbone of our durable brake discs.
2. ECE R90-Certified Consistent Performance
All discs meet strict ECE R90 safety standards, validated by 100,000+ km of real-world testing. Brake force deviation remains below 5% across speeds and loads—critical for safety in stop-and-go traffic or highway driving. This certification isn’t just compliance; it’s proof of predictable, fail-safe performance that drivers and mechanics trust.
3. 40% Longer Wear Life vs. Standard Aftermarket
Engineered with a dense friction layer, our discs outlast generic options by 40% (tested to 100,000 km). A low-friction coating also reduces pad wear—cutting maintenance costs for end-users. For repair shops, this means fewer callbacks and stronger customer loyalty for your brake solutions.
4. Low-Noise, Dust-Minimizing Design
Unique circumferential grooves disrupt air flow and dust buildup, reducing braking noise by 15% vs. non-grooved discs. This eliminates annoying squeals and keeps wheels cleaner—addressing a top driver complaint. Paired with precision machining, you get a quiet, low-maintenance ride without sacrificing performance.
5. OEM-Spec Fit for Hassle-Free Installation
Every disc is machined to Lifan’s original tolerances, ensuring a perfect fit—no modifications needed. Installation time drops by up to 20% vs. ill-fitting generic parts, saving mechanics labor and customers time. Ideal for both professional repair shops and DIY enthusiasts seeking an OEM-grade upgrade.
Technical Parameters
| Parameter | Specification | Test Standard/Validation |
| Material Composition | High-grade gray cast iron (EN 1561 standard) with graphite flakes ≤3% | ISO 6507-1 hardness testing; optimized for heat dissipation & wear resistance
|
| Dimensions (Typical) | Diameter: 260–320mm; Thickness: 22–28mm; Hub Bore: 70–80mm | CNC-machined to ±0.05mm tolerance; ensures OEM-spec fitment |
| Weight | 12–18kg (varies by size) | Precision balance testing; lightweight design reduces unsprung mass for improved handling |
| Heat Treatment | T400-grade induction hardening | Surface hardness: HRC 45–50; core hardness: HRC 28–32—prevents warping under extreme heat |
| Wear Resistance | ≤0.02mm wear per 10,000km (vs. 0.035mm for generic discs) | SAE J661 wear testing; 40% longer lifespan than standard aftermarket discs |
| Thermal Stability | Thermal deformation: ≤0.05mm after 10 consecutive 100km/h–0km/h stops | ISO 16231 thermal stress testing; reduces fading & maintains consistent braking force |
| Noise & Vibration Control | Groove design cuts braking noise by 15% (dB reduction: 68dB vs. 78dB for smooth discs) | NVH testing per ISO 5130; minimizes driver discomfort |
| Certifications | ECE R90 (EU), ISO 9001:2015 (Quality Management) | Third-party validated for safety, consistency, and production standards |
| Surface Finish | Machined with anti-corrosion coating (zinc-phosphate) | Salt-spray test: ≥500hrs without rust; extends service life in humid climates |
Product Uses
Here are specific application scenarios of brake disc:
1. Daily Urban Commuting
Tailored for stop-and-go city driving, our discs reduce noise by 15% via circumferential grooves—eliminating annoying squeals. With a low wear rate of 0.02mm per 10,000km(SAE J661 tested), they minimize pad/disc replacements, perfect for drivers prioritizing comfort and low maintenance. Backed by 15+ years of brake R&D, they deliver reliable stopping power for daily routines.
2. Highway Long-Distance Travel
Built for sustained high-speed braking, the T400-hardened surface (HRC 45–50) limits thermal deformation to ≤0.05mm after 10 consecutive 100km/h–0 stops (ISO 16231 tested). This prevents “brake fade” and maintains consistent force—critical for highway safety. ECE R90-certified, they ensure peace of mind on cross-country trips.
3. Harsh Weather Regions
Survives humidity, rain, or dust with a zinc-phosphate anti-corrosion coating (500+ hours salt-spray tested, ISO 9227) and dust-minimizing grooves. Reduces rust/debris buildup, cutting maintenance in challenging climates—perfect for drivers needing long-term durability.
4. Professional Repairs & DIY Upgrades
Machined to OEM tolerances (±0.05mm), they install 20% faster than ill-fitting parts—saving mechanics labor and DIYers time. Trusted by global repair networks, these discs offer a hassle-free, OEM-grade replacement for routine maintenance or performance boosts.
Product Operate Guide
Before installation, clean the wheel hub bore with a wire brush—ensures a tight ±0.05mm fit (our precision spec). Torque lug nuts to 20 Nm (ISO standard) to prevent warping. For the first 500km, avoid hard braking: this “beds in” discs/pads, maximizing lifespan (tested to 100,000km+). Regularly inspect for dust; our zinc-coating resists corrosion. Follow these, and enjoy consistent, quiet braking from day one.
