Brake Discs Features:                                                   

•Equivalent to OE design

Manufactured to match original‑equipment dimensional, structural and tolerance standards. Direct bolt‑on replacement for factory original parts; no vehicle modification needed.

•Smooth and quick stop

Delivers linear, consistent braking force without jerking. Provides responsive, reliable stopping performance, free of brake judder or pull.

•Anti-rust

Non‑friction surfaces are treated with protective coating against moisture, rain and road salt. Prevents corrosion and hub seizing. The friction contact area will clean itself during braking.

•Low noise, low dust

Minimizes brake squeal and unwanted noise during braking. Generates less brake dust to keep wheel rims clean.

•Optimal thermal performance

Excellent heat‑dissipation capability. Controls high heat generated by heavy or repeated braking, reduces thermal‑related risks such as brake fade and thermal cracking.

• Precision dynamic balance

Each unit passes strict dynamic‑balance testing. Eliminates steering wheel vibration under high‑speed braking. 

• Thermal‑crack resistance

High‑grade grey cast‑iron material resists heat‑induced cracks under heavy‑load braking, extending service lifespan. 

• Stable friction compatibility

Matches perfectly with most OE and aftermarket brake pad formulas, maintains consistent braking output. 

• Zero run‑out control

Tight thickness variation& run‑out tolerance, prevents premature pad wear and pulsation during braking.

Brake Pads Features:

•High performance

Stable friction coefficient under varied driving conditions. Confident, dependable stopping power for daily and demanding driving scenarios.

•Long-life service

Superior wear‑resistant formula. Extends service mileage, reduces frequent replacement frequency.

•Anti-fade

Resists brake fade under continuous hard braking. Maintains steady braking power even when components get hot.

•Low noise, low dust

Suppresses brake squeals and vibration‑related noise. Produces minimal abrasive dust accumulation on wheels.

•Environmental friendly

Non‑asbestos friction material. Contains no harmful heavy‑metal substances, meets global environmental requirements for auto spare parts.

• Gentle on brake discs

Optimized friction formula avoids aggressive abrasion, reduces wear to matching brake rotors.

• Good cold braking response

Secure stopping performance even at low ambient temperature, no weak braking when parts are cold.

• Stable in wet condition

Maintains dependable braking force on rainy or wet road surfaces.

Application Scenarios

• Aftermarket replacement for passenger cars & SUVs, mainly for front‑wheel braking. (Ventilated discs for front wheels; solid discs are commonly used for rear wheels.)

• Auto‑parts wholesale, repair‑shop service and overseas export business.

• Suited for daily commuting and highway driving with frequent braking.

Difference between Ventilated & Solid Brake Discs

• Ventilated Brake Disc: Hollow internal vane structure, thicker overall dimension, outstanding heat dissipation, widely used on front axles bearing higher braking load.

• Solid Brake Disc: One‑piece solid cast‑iron structure, thinner and lower‑cost, weaker heat dissipation, generally applied to rear wheels.

Certification: IATF16949, ISO14001, ISO45001, ECE R90, AMECA

• IATF16949: Global automotive quality management system, basic requirement for auto spare‑parts manufacture.

• ISO14001: Environmental management system.

• ISO45001: Occupational health & safety management system.

• ECE R90: European regulation for aftermarket brake components, mandatory for EU market sales.

• AMECA: US automotive parts certification, for North‑American aftermarket access.

Material: Gray Iron, High Carbon, G3000, GG15HC, DIN, SAE

These are global standard cast‑iron grades for brake discs:

• Gray Iron / High‑carbon cast iron: Base material for brake rotors, good damping capacity, stable friction performance, heat‑crack resistance.

• G3000: US standard SAE‑G3000, widely‑used high‑strength gray iron for aftermarket brake discs.

• GG15HC: European‑style high‑carbon cast‑iron grade for brake rotor.

• DIN / SAE: Follow German DIN and American SAE material industrial standards.

Surface Finish & Color Options

Color: Gray, black, metal, gold Multiple surface treatments for the non‑friction hat/hub area to satisfy different market aesthetic and anti‑rust demands:

• Gray: Original as‑cast surface

• Black: Electrophoretic / spray‑paint coating, most popular for global aftermarket

• Metal: Natural bare metallic finish

• Gold: Golden anti‑rust protective coating

• 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
