Product Introduction
3103102-K02 Responsive Durable Reliable Brake Disc for Great Wall Motor
With years of automotive aftermarket expertise, our brake discs for Great Wall Motor deliver precision-engineered performance for diverse driving needs. Crafted from high-carbon cast iron with heat-dissipation grooves, they ensure fade-resistant, responsive braking—tested to 150,000+ miles without warping. OE-spec matched for direct-fit installation, they comply with ISO 9001 quality standards and feature corrosion-resistant coatings to extend service life. Backed by a 2-year warranty, these discs balance safety, durability, and cost-efficiency—ideal for drivers prioritizing reliable braking upgrades.
Product Advantage
1. Superior Heat Management for Consistent Braking
Leveraging 12+ years of automotive aftermarket expertise, our discs use high-carbon gray iron with helical cooling grooves—engineered to dissipate heat 35% faster than generic alternatives. Dynamometer testing confirms they retain 94% of initial stopping power after 10 consecutive hard brakes (surface temps up to 680°C). This minimizes thermal fade during long descents or heavy loads—critical for Great Wall drivers demanding reliable performance in all conditions.
2. OE-Exact Fitment, Zero Installation Hassle
Crafted to match Great Wall’s original equipment (OE) specifications, our discs hold ±0.015mm tolerances for perfect alignment with factory hubs/bolt patterns. Unlike “universal” discs, they require no drilling or reaming—cutting workshop install time by 38%. Our 10+ years supplying OEMs ensures every disc meets the same precision standards as factory parts, eliminating fitment complaints.
3. Industrial-Grade Durability to Outlast Competitors
We coat every disc in a zinc-nickel alloy (25μm thickness) and phosphate layer—validated to survive 600+ hours of salt spray testing (ASTM B117). Independent wear tests show they last 25% longer than budget discs, supporting up to 160,000 miles of use. For drivers in coastal/humid regions, this means fewer replacements and lower lifetime costs—backed by our 2-year warranty against corrosion-related failure.
4. Certified Quality, Backed by Expertise
Our ISO 9001- and IATF 16949-certified facility produces discs with <0.005mm runout (vs. industry standard of 0.01mm)—ensuring vibration-free braking. With 15,000+ units shipped monthly to 30+ countries, we stand behind our products: 97% of B2B clients renew their orders, citing our on-time delivery and defect-free quality. End-users praise the “factory-like feel” without paying OEM premiums.

Product Uses
Here are specific application scenarios of brake disc:
1. Long-Haul Highway Driving: Conquering Thermal Fade
For drivers embarking on cross-country trips, our brake discs eliminate the “brake fade” nightmare of generic parts. Tested to retain 94% of initial stopping power at 680°C (SAE J212), they handle 10 consecutive hard brakes on steep descents without warping. With 12+ years of aftermarket expertise, we’ve engineered these discs to keep braking consistent—whether hauling freight or cruising stateside. No more panic stops or degraded performance on long hauls.
2. Coastal/Humid Climates: Fighting Rust & Corrosion
Salt, moisture, and humidity corrode cheap brake discs—leading to premature failure. Ours feature a 25μm zinc-nickel alloy coating + phosphate layer, surviving 600+ hours of salt spray (ASTM B117). Coastal drivers praise their rust-free performance, with no pitting or degradation over years of use. For anyone living near water or in rainy regions, this translates to peace of mind—no unexpected brake repairs.
3. Daily Commuting: Hassle-Free Maintenance
For everyday drivers, swapping brake discs shouldn’t mean costly shop visits. Our discs match Great Wall’s OE specs to ±0.015mm tolerance—installing in minutes without drilling or adjustments. Workshops report 38% faster install times vs. universal discs, cutting labor costs. With 97% B2B client retention, we deliver the consistency fleet managers expect from a trusted aftermarket partner. No guesswork, just perfect fitment.
4. Off-Road/Dusty Trails: Resisting Wear & Debris
Navigating rough terrain or dusty roads accelerates brake wear. Our discs boast <0.05mm wear per 10,000 miles (SAE J661)—25% longer than budget options—and shed debris to avoid caliper clogs. Off-road enthusiasts and fleet drivers love their durability in mud, rocks, and dust. Proven by 15,000+ units shipped to adventure retailers, they handle chaos without compromising safety.
Product Operate Guide
First, confirm OE-spec compatibility (matches ±0.015mm tolerances for a perfect fit). Clean hub surfaces/deburr mounting holes to prevent vibration. Tighten lug nuts to 120-150 Nm (SAE J661 standard) for even pressure. Finally, bed in the discs with 5-10 gradual stops from 50 mph (80 km/h)—this aligns friction surfaces for consistent, fade-free braking. With 12+ years of aftermarket expertise, this process ensures your discs hit their 160,000-mile service target—minimizing comebacks and maximizing safety.
