Rear Brake Disc Of CHERY Arrizo

Most owners choose the VELA V5 for its spacious interior. It is highly practical for multiple scenarios: dropping kids off at school on weekdays, taking family trips on weekends, transporting luggage back to hometown during festivals, and even hauling small cargo for friends occasionally. However, many long-term owners have complained about defects of the original brake discs. Newly replaced discs will develop rust after just a weekend of parking, and the issue worsens in the rainy season. Frequent stop-and-go driving in urban traffic also causes faint abnormal noises from the brakes. When driving at high speed with a full load, the brake pedal feels spongy, and the steering wheel tends to hake after prolonged use.

Our Rear Brake Disc of CHERY Arrizo B143502075 is an upgraded product targeting all these problems. It fully complies with Chery's original brake system specifications, with improved materials, coatings and manufacturing techniques. It effectively eliminates rust, abnormal noises and steering vibration. Whether you drive on the highway at 120 km/h with your family or navigate busy morning traffic in the city, you can enjoy stable, quiet and smooth braking with complete peace of mind.

Advantages of Nano-Ceramic Composite Spray Coating Technology
Frankly speaking, rusting is the top headache for most car owners after replacing brake discs. I have seen many cases where brand-new brake discs develop a ring of yellow rust after just one rain. When you hit the brakes on Monday morning, there will be loud clattering noises that last for quite a while until the rust is worn off, which is extremely annoying. This problem is even worse for people living in southern regions. During the plum rain season, brake discs will get heavily rusted if the car is parked downstairs for two or three days. For those who often travel to coastal areas, the heavy salt mist accelerates rusting significantly.

Our Rear Brake Disc of CHERY Arrizo B143502075 adopts a nano-ceramic composite epoxy resin spray coating, which is far superior to ordinary cheap black spray paint sold in cans. Its production process is three times more complex than that of regular coatings.

First of all, zinc phosphating pretreatment is carried out before spraying paint. This process thoroughly removes oil stains and impurities on the brake disc surface and forms a dense phosphating film, which greatly enhances the adhesion of the coating and prevents it from peeling off within two months. After that, we apply epoxy resin paint mixed with nano-ceramic particles evenly via electrostatic spraying. Electrostatic spraying ensures a uniform coating without uneven thickness. Subsequently, the brake discs are placed in a high-temperature oven at 200°C for 30 minutes of curing, so that the coating fuses tightly with the brake disc and cannot be scraped off easily.

The thickness of the finished coating is strictly controlled between 30 and 35 micrometers, more than double the original factory coating thickness of 15 to 20 micrometers. Test results show that this coating can withstand 800 hours of neutral salt spray test, a 60% improvement over the original factory standard of 500 hours. To put it simply, the brake disc will stay rust-free even if the car is parked in an open-air coastal parking lot for a whole month. You also have no need to worry about rust caused by rain, car washing or de-icing agents splashed on the road during highway driving. There is no longer any need to slam on the brakes repeatedly at the start of a trip to wear away rust.

In addition, the coating is fully eco-friendly and compliant with the EU RoHS standards. It contains no heavy metals and causes no environmental pollution. Products with this coating can pass inspections smoothly and be exported to Europe, Australia and other regions with strict environmental regulations

Our intelligent production lines operate non-stop with robots. Precision here relies on data rather than manual dexterity.When it comes to brake discs, material formulation is important, yet the core lies in the foundry and precision processing equipment. Many low-cost small workshops on the market still adopt manual molding and conventional lathes, resulting in products with poor uniformity and frequent issues such as eccentricity and vibration. In contrast, our model B143502075 is manufactured via fully automatic green sand high-pressure molding and CNC precision machining, a rigorous and high-standard production approach.For rough casting, we apply the industry-leading riserless casting technology, which fundamentally eliminates hidden defects like shrinkage cavities and sand holes. This technology boosts the casting yield to over 95% and keeps the shrinkage cavity rate below 0.4%. It ensures highly uniform tensile strength of HT250 cast iron workpieces, with the tensile strength reaching no less than 206MPa and hardness ranging from 187 to 241 HBS.The precision machining stage features an advanced working scenario. Industrial robots work around the clock in a constant-temperature workshop to handle material picking and feeding. The Danish DISA molding line operates in tandem with Doosan vertical CNC machining centers. The entire process, from loading rough castings and cutting and forming workpieces to 100% on-line dynamic balance testing, is monitored in real time by the MES manufacturing execution system. High-precision contact measuring instruments detect tolerances within 0.001 millimeters, eliminating human errors throughout production. Thanks to these tireless robotic units, we confidently guarantee the face runout tolerance is within 0.05 millimeters. Every brake disc is marked with a laser-etched traceability code before delivery. You can simply scan the code to check its production batch and processing equipment.

Q: I repaired an old 2010 Chery V5. The customer reported a squeaking noise when braking gently at low speeds after replacing the brake discs. Could it be a problem with the new discs?

A: Don't rush to replace the brake discs. The issue is most likely that the brake pads have not fully run in with the new discs, or the lubricant on the guide pins of the calipers of this old vehicle has dried out, causing sluggish retraction. As long as there are no hard grooves deeper than 0.3 millimeters on the disc surface, the squeaking sound during gentle low-speed braking is a normal resonance generated during the running-in period. Ask the customer to drive normally for 500 to 800 kilometers to fully wear off the factory texture on the surface of the new discs and the brake pads, and the noise will disappear naturally. If the sharp abnormal noise persists after the running-in phase, bring the vehicle back to check whether the anti-noise shims on the back of the brake pads are loosely fitted, or if the dust boots of the caliper pistons are damaged.

Q: Can the part number B143502075 be directly installed on my Chery Eastar 2.0L?

A: If the rear axle of your Eastar (B11 series) has not been modified, this set of parts numbered B143502075 is manufactured strictly in accordance with the original 288-millimeter standard and can be installed directly at the original mounting positions. While replacing the brake discs, take the opportunity to check if the rear handbrake cables are aged and stuck, and whether the dust boots of the rear brake calipers are cracked and leaking oil. Since the components are already disassembled, a thorough inspection and maintenance in this area will save the customer from trouble during use.

Q: For this batch of Chery brake discs shipped to coastal cities, there is no rust on the outer ring of the disc surface, but slight surface rust appears on the inner edge of the disc hub. Why is this?

A: This is a very common phenomenon and there is no need to worry. Our B143502075 brake discs are coated with water-based eco-friendly Dacromet coating on non-friction areas, which is mainly applied to disc hubs, edges and ventilation grooves for anti-corrosion purposes. Nevertheless, brake discs are made of cast iron. When stored for a long time in sea freight containers with high salt spray and poor air circulation, a small number of disc edges may develop slight surface rust that can be easily wiped off, which will not affect the cast iron base material at all. The friction surfaces of brake discs are exposed gray cast iron by design to ensure optimal friction coefficient. Even if there are rust spots on them, a few brake applications after installation will restore them to a clean state. Important reminder: Never apply ordinary paint or engine oil to the friction surfaces of brake discs for rust prevention on your own. High temperatures will cause brake failure and lead to serious accidents.

New Threshold for Overseas After-sales Business in 2026: Brake Discs Without ECE R90 Certification and Eco-friendly Coatings May Become Unsellable

Fellow exporters focusing on European and Middle Eastern markets have likely caught wind of the latest updates. As the EU rolls out stricter environmental and technical access regulations, especially the Euro 7 emission standard which will for the first time impose restrictions on brake particulate emissions, the entry bar for exported brake discs has been raised significantly.

Industry insiders predict that after 2027, the ECE R90 certification (E-mark) for the independent aftermarket will become a mandatory basic requirement. This certification is far more than just a label; it mandates that brake discs must pass thermal fade tests involving 100 consecutive high-temperature braking cycles and durability tests simulating 150,000 kilometers of road operation.

Additionally, traditional Dacromet coatings have been gradually phased out across the industry due to their chromium ion content, and chromium-free zinc-aluminum coatings have become the mainstream choice. Our model B143502075 undergoes 100% on-line dynamic balance inspection before leaving the factory, with extremely low single-sided unbalance. It is also equipped with standard chromium-free eco-friendly coatings. If you plan to export these brake discs to the EU, the Middle East, South America or even North America, you do not need to worry about compliance issues, and we can provide full support for customs declaration documents. Should you require versions engraved with the ECE R90 E-mark in the future, you may inform our sales manager when placing orders in advance, and we will arrange production via a dedicated channel.
