Brake Disc for JEEP Front ECE R90

Brake Disc Features:                                                   

•Equivalent to OE design 

•Smooth and quick stop 

•Anti-rust 

•Low noise, low dust 

•Optimal thermal performance 

•Superior Heat Management for Consistent Performance: The front brake discs are designed with unique honeycomb ventilation holes. This structure helps to dissipate heat more effectively, significantly reducing brake fade and maintaining excellent braking performance even during demanding conditions like prolonged mountain driving.

•Large Brake Disc Area: To match the vehicle's performance requirements, the front brake discs on models like the Grand Commander have a larger surface area compared to other vehicles in its class. A larger disc area generally contributes to greater braking force and improved heat dissipation.

Manufactured in Shandong, China, this high-performance brake disc (rotor) is engineered to deliver OEM-equivalent fitment, smooth and responsive stopping power, and long-lasting corrosion resistance. Built for the worldwide aftermarket, it combines high-carbon metallurgy, precision machining, and flexible customization to serve distributors, workshops, and performance retailers across diverse markets.

1. Material & Metallurgy

Crafted from premium Gray Iron and High Carbon cast iron, strictly conforming to G3000, GG15HC, DIN, and SAE standards. The elevated carbon content enhances thermal capacity and structural stability, effectively minimizing brake squeal, judder, and thermal cracking under repeated heavy braking. A uniform metallographic structure ensures consistent friction output, predictable pedal feel, and extended service life—even under aggressive driving.

2. Precision Machining

Every disc is produced through precision turning and grinding:

• Tight tolerances – Strict control of Disc Thickness Variation (DTV) and lateral runout eliminates steering-wheel vibration.

• Dynamic balancing – Every rotor is balanced to prevent high-speed pulsation.

• Fine surface finish – Promotes rapid pad bedding-in and reduces break-in noise.

• Dimensional verification – Overall height, center bore, bolt circle, and minimum thickness are checked against OEM drawings.

3. Anti-Rust & Surface Finish

A full range of anti-corrosion treatments for harsh global climates: Oiled, Painted, Coated, and Zinc Dust. Standard colors: Gray, Black, Metal, Gold. These layers shield hubs, vanes, and non-friction areas from road salt, moisture, and grime—greatly extending service life in coastal, snowy, and humid regions.

4. Structural Variants (Clear Distinctions)

Not one-size-fits-all. The line is divided by structure to match exact platforms and axles:

• Solid – Economical for light-duty cars and rear axles.

• Vented – Internal channels accelerate heat dissipation; ideal for front axles.

• Drilled & Slotted – Holes release heat and vent friction gas; slots sweep dust, water, and debris for consistent friction. Ideal for SUVs and performance use.

• Custom designs – Bespoke drilling, slots, and hat profiles based on drawings or samples.

5. Thermal Performance & Braking Feel

Engineered for optimal heat dissipation and resistance to brake fade, the high-carbon formulation and vented/drilled/slotted designs stabilize friction under sustained braking. The result: smooth, quick stops with low noise and low dust, consistent pedal feel, and confident deceleration for both daily commuting and spirited driving.

6. Quality Certifications & Traceability

Produced under IATF16949, ISO14001, and ISO45001 certified systems. Products comply with ECE R90, SAE, and AMECA standards. Every batch undergoes hardness inspection, metallographic analysis, salt spray testing, thermal fatigue testing, and noise evaluation. Full batch traceability with inspection reports is provided for international buyers.

7. Design & Engineering Details

• OE-equivalent design for direct bolt-on replacement—no modification required.

• Optimized vane geometry (on vented discs) maximizes airflow and cooling efficiency.

• Chamfered edges on drilled holes reduce stress concentration and cracking risk.

• Directional slots ensure continuous debris evacuation regardless of rotor rotation.

8. Customization & Packaging

• Private label & branding – Laser marking, screen printing, or embossed logos.

• Packaging – Color boxes, neutral cartons, pallets, bulk (Box / Carton / Pallet / Bulk), custom-branded artwork supported.

• Product development – OEM sample analysis, drawing-based development, and trial production.

• Logistics – Flexible container loading with mixed SKU consolidation for distributors.

9. Application Fields

• 100% critical dimensions, runout and DTV inspection 

• Material physical and chemical inspection

• Test shear strength, compressibility, density, flatness and parallelism 

• Test performance and noise/NVH
