Product Advantage
Premium Material & Authoritative Certifications
Our brake disc is made of high-quality carbon alloy steel, selected through 18+ years of experience in automotive brake components R&D. It has passed strict ISO 9001 and IATF 16949 certifications, meeting global safety standards. The material’s hardness reaches 220-250 HB, ensuring strong load-bearing capacity and avoiding cracks during high-intensity braking, making it a reliable high-performance brake disc.
Precision Machining for Stable Braking
We adopt CNC precision machining technology with a machining accuracy of ±0.02mm, ensuring the brake disc’s surface flatness and concentricity. This reduces the runout to less than 0.05mm, avoiding brake vibration and noise. Its friction coefficient remains stable at 0.38-0.42, providing consistent braking force even in wet or low-temperature environments, effectively improving the overall braking efficiency of the brake system.
Heat-Resistant Structure to Prevent Warping
The brake disc features a special heat-dissipating rib design, which increases the heat-dissipating area by 35% compared to ordinary brake discs. It can withstand temperatures up to 380℃ without warping, solving the common problem of brake disc deformation caused by long-term high-temperature braking. The low thermal expansion coefficient (≤12×10⁻⁶/℃) ensures dimensional stability, extending the brake disc’s service life.
Enhanced Durability & Corrosion Resistance
After undergoing a multi-layer galvanizing process, our brake disc has excellent corrosion resistance, passing a 500-hour salt spray test without rusting—far exceeding the 200-hour industry average. Its wear resistance is also enhanced: compared to generic brake discs, it reduces wear rate by 28%, extending the service life by 30%+, reducing the frequency of replacement for users and lowering maintenance costs.
Rigorous Quality Testing & Wide Adaptability
Every brake disc undergoes 100% factory inspection, including dynamic balance testing, pressure testing, and friction performance testing, with a qualified rate of 99.8%. It is designed to fit various brake system configurations, compatible with multiple brake caliper types. Our professional technical team provides pre-sales adaptation consultation, ensuring the brake disc matches your needs perfectly, making it a trusted choice for automotive aftermarket users.

Product Uses
Here are specific application scenarios of brake disc:
1.Urban Daily Commuting
Ideal for frequent stop-and-go in cities. Its stable friction coefficient (0.38-0.42, ISO 26867) ensures consistent braking, while ≤55dB vibration damping (ISO 3744) reduces noise. Withstands 380℃ continuous high temperatures from repeated braking, avoiding warping and ensuring daily travel safety.
2.Mountainous & Rough Terrains
Adapts to steep slopes and uneven roads. G6.3 dynamic balance (ISO 1940-1) minimizes vibration during downhill braking, while ≤0.05mm radial runout (SAE J2125) ensures stable contact with calipers. Surface hardness (32-38 HRC) resists impact damage from rough roads.
3.Harsh Climate Conditions
Performs in rainy, snowy, or coastal areas. Wet friction coefficient remains 0.38+, avoiding brake failure. 500-hour rust resistance handles salt-laden air, and low thermal expansion (≤12×10⁻⁶/℃) prevents cracking in extreme temperature changes (from -20℃ to 30℃).
4.Performance Modification & Upgrade
Fits users pursuing enhanced braking. Withstands 420℃ short-term peak temperatures (ISO 6312) for high-intensity driving (e.g., mountain racing). Surface hardness (32-38 HRC) boosts wear resistance, meeting performance needs beyond standard brake discs.
5.Fleet & Commercial Vehicle Operations
Ideal for taxi fleets or delivery vehicles. 99.8% factory pass rate ensures batch reliability, and 30% longer service life reduces replacement frequency. Compatible with multiple caliper types, simplifying fleet parts management and lowering maintenance labor costs.
Product Operate Guide
Pre-Installation
CheckClean the brake disc surface (remove oil/dust) per ASTM A29 standards. Inspect for cracks—if radial runout exceeds 0.05mm (SAE J2125), avoid use. Ensure compatibility with your brake caliper to prevent abnormal wear.
Installation
TipsTighten mounting bolts to 25-30 N·m torque (aligning SAE J2125). After installation, idle for 5 minutes to test dynamic balance (G6.3 grade, ISO 1940-1) and avoid immediate high-speed braking.
In-Use Care
Avoid over 5 consecutive hard brakes (prevents exceeding 380℃ continuous temp, ISO 6312). Check wear every 5,000km—replace if thickness drops by ≥3mm. Keep disc dry in rain to maintain 0.38-0.42 friction coefficient (ISO 26867).
