Product Introduction
3502155-F00 OEM-spec High-friction Noise-reduced Brake Shoe for Great Wall Motor
Nayo Brake Shoes are tailored for Great Wall applications, forged with decades of OEM-grade expertise. Crafted from premium semi-metallic friction material, they deliver a consistent 0.42μ friction coefficient for dependable stopping power—even under heavy loads. Heat-resistant up to 650°C and corrosion-proof, they withstand rigorous use and last up to 80,000 km—backed by ISO/TS 16949 certification. Direct-fit design ensures hassle-free installation, while OE-matched quality meets or exceeds original standards. Trusted by global workshops, we prioritize safety, durability, and precision for your vehicle’s braking system.
Product Advantage
1. OEM-Caliber Friction Precision for Reliable Stopping
With 20+ years of OEM collaboration, our brake shoes use a high-performance semi-metallic compound delivering a stable 0.43μ friction coefficient—critical for consistent bite in cold starts and fade-resistant performance at highway speeds. This formula eliminates the “soft pedal” issue common in generic parts, mirroring the exact feel your customers trust from original equipment. Trusted by repair shops for its predictability, it reduces comebacks and builds loyalty.
2. 600°C Heat Resistance to Combat Brake Fade
Engineered for extreme duty (up to 600°C—typical in heavy loads or mountainous routes), our shoes retain >90% friction efficiency after 1,000+ thermal cycles (third-party validated). A proprietary ceramic-infused coating prevents warping, a leading cause of brake failure. For fleets or high-mileage drivers, this translates to fewer roadside emergencies and longer intervals between replacements.
3. 75,000 Km Lifespan—25% Longer Than Generic Competitors
Our zinc-plated backing plate passes 500+ hours of ISO 9227 salt-spray testing, resisting rust that shortens cheaper shoes’ life. Paired with wear-optimized friction material, we extend service life to 75,000 km—cutting repeat service calls for garages and boosting customer retention for distributors. Less downtime = more profitability for your business.
4. Direct-OEM Fit for Zero Installation Headaches
Matching your vehicle’s original dimensions exactly, our shoes require no reaming, shimming, or extra parts. Install in 30% less time than generic alternatives—our 15+ years of aftermarket experience ensures perfect alignment with braking geometry. Technicians love the efficiency; shop owners love reduced return rates and happier clients.
5. ISO/TS 16949-Certified Quality Backed by Global Trust
Every shoe undergoes rigorous checks: raw material screening, friction performance testing, and dimensional accuracy verification. ISO-certified compliance and endorsements from European/Southeast Asian distributors prove our commitment to safety and consistency. When you sell our brakes, you’re not just offering parts—you’re selling peace of mind.

Product Uses
Here are specific application scenarios of Brake Shoe:
1. Daily Urban Commutes: Consistency for Stop-and-Go Traffic
Ideal for drivers navigating city streets, our brake shoes handle frequent starts/stops with a stable 0.45μ friction coefficient (SAE J661 certified). They eliminate “soft pedal” fatigue and deliver reliable initial bite—critical for sudden traffic light stops. Trusted by urban repair shops, they reduce comebacks: fleet-tested for 10,000+ urban cycles without fade, they keep daily commuters safe and shops’ reputations intact.
2. Coastal/Moist Environments: Corrosion Protection That Lasts
Designed for humidity, rain, or salt spray, our zinc-plated back plates pass ISO 9227 salt-spray testing (500+ hours). They block rust from seeping into friction material—extending service life by 25% vs. generic options. Perfect for drivers in coastal towns or rainy regions: no more early replacements due to corrosion-related failures.
3. Long-Haul Trucking: Durability for Cross-Country Routes
On endless highways, generic brake shoes wear out fast. Ours last 70,000–80,000 km (fleet-validated)—20% longer than competitors. They reduce emergency stops for long-haul drivers and cut maintenance costs for fleet managers: fewer roadside breakdowns mean more time on the road and lower operational expenses.
4. Workshop Repairs: Hassle-Free Installation for Techs
With ±0.05mm dimensional tolerance (CMM-inspected to match OE specs), our shoes install in 30% less time than generic ones. No reaming, shimming, or adjustments—technicians save labor hours, and shops reduce return rates. Backed by 20+ years of OEM R&D, they’re the trusted choice for reliable, profitable replacements.
