The Front brake disc for Citroën C4 Picasso MPV 4246C0 is compatible with a wide range of cars, as follows:

The Front brake disc for Citroën C4 Picasso MPV 4246C0 corresponds to several different codes.

To ensure this brake disc can operate in various complex environments across different regions worldwide, it features a five-layer industrial-grade anti-corrosion coating system that creates a fully enclosed protective layer from inside to outside. Here is how this process works: First, high-frequency ultrasonic equipment is used to thoroughly clean the castings, removing all debris, oil contaminants, and impurities from the small holes on the disc surface; this ensures that the subsequent coating adheres securely without forming bubbles or peeling off. After cleaning, the disc is transferred to a passivation tank, where a dense oxide film is formed-effectively blocking corrosion from reaching the material itself and thereby enhancing its anti-corrosion performance. Next, high-pressure airless spraying is employed to apply an epoxy anti-corrosion primer evenly over the disc surface, filling the small pits on the surface; this constitutes the first anti-corrosion barrier and also helps the central coating adhere more firmly. Following the primer application, another anti-seepage isolation layer is sprayed to block external water vapor and salts from penetrating inward, while simultaneously alleviating the stress exerted on the coating by temperature fluctuations. Finally, a weather-resistant topcoat is applied, which is then cured in a high-temperature oven to form a dense, wear-resistant surface layer that is both scratch-resistant and aging-resistant. Laboratory tests have shown that this coating system can withstand a neutral salt spray test for over 600 hours without showing any visible rust, with the coating adhesion meeting ISO Class 1 standards. Furthermore, after undergoing 200 cold-hot cycle tests, the coating showed no cracking or peeling; it performs flawlessly even under harsh conditions such as coastal saline-alkali soils, roads salted during winter, or humid mountainous environments. 

Our products are manufactured in a fully enclosed, constant-temperature intelligent workshop! The workshop temperature is tightly controlled within an accuracy of ±0.8°C-any temperature fluctuations that could compromise machining precision are completely eliminated! Our production line is equipped with high-end machining and inspection equipment, including imported CNC precision lathes, fully automated dynamic balancing inspection lines, and three-dimensional coordinate measuring machines; all core processes are fully automated, minimizing manual errors to the absolute minimum-truly impressive, isn't it? To ensure that every single product maintains exceptional quality, we have established a comprehensive four-tier quality control network covering the entire production cycle, ensuring that no substandard products ever leave our facility:

✅ Raw materials entering the plant must undergo spectral analysis: for every batch of high-carbon cast iron raw materials, a rigorous spectral composition test must be conducted to confirm that the proportions of carbon, silicon, manganese, and other elements strictly comply with the material specifications-ensuring the mechanical properties of the component are tightly controlled from the source!

✅ Semi-finished product process: scheduled periodic inspections are performed at each processing stage; during machining, point-based inspections are carried out at every step, and key dimensions are additionally subject to sampling re-measurement; any detected parameter deviation is corrected immediately to eliminate any potential risks!

✅ Finished products: full-dimensional verification is performed on each unit-key indicators such as thickness, runout, and parallelism are thoroughly checked; any product failing these criteria is directly rejected!

✅ Batch sampling for aging simulations: samples from each batch are taken to undergo aging tests such as braking simulations and thermal cycling tests, effectively validating whether the product's performance under real operating conditions is sufficiently robust! With the support of this comprehensive full-process quality control system, our product's pass rate upon leaving the factory consistently remains above 99.7%! Furthermore, each batch of products comes with a corresponding factory inspection report attached, providing complete evidence for our major clients' quality control verification-guaranteeing absolute reliability and peace of mind.

Can OE-4246C0 brake discs be supplied with official material testing reports for customer qualification reviews?
Answer: Yes. Each batch of products is accompanied by an independent raw material spectral analysis report and a finished product dimensional inspection report; formal paper or electronic versions stamped with the company's official seal can be provided either as part of the shipping documents or sent separately, fully meeting the supplier qualification review and product warehousing verification requirements of major clients.

Can the original OE-numbered products be supplied in a long-term, stable locked quantity?

Answer: Yes. For core standard models such as OE-4246C0, we have established dedicated production capacity reserves. For customers who have signed annual locked-quantity agreements, we will reserve exclusive production capacity and maintain safety stock, ensuring stable supply throughout the agreed period, regardless of fluctuations in market raw material prices or production capacity constraints.

Can obsolete inventory be negotiated to be exchanged for high-demand models of equivalent value?
Answer: For our annual strategic cooperation customers, we support exchanging unopened obsolete inventory-provided that it does not affect secondary sales-with high-demand models of equivalent value within the terms specified in the contract, thereby helping customers optimize their inventory structure and reduce the risk of inventory overstocking; specific exchange rules shall be governed by the cooperative framework agreement.

Lightweight Brake Design Specifications for New Energy Vehicles: As the penetration rate of new energy vehicles globally continues to rise, brake discs must achieve lightweighting while maintaining sufficient strength to offset the increased load resulting from the added weight of the battery. We have mastered advanced lightweight design technologies utilizing high-carbon materials, enabling us to meet the specific requirements for brake system integration in new energy vehicles.

Thermal resistance requirements for braking components in the Middle East region: The high-temperature markets in the Middle East impose mandatory thermal stability requirements on braking components; under prolonged high-temperature operating conditions, issues such as a sudden decline in braking performance or coating detachment must not occur. This product has been validated through high-temperature thermal cycling tests and is fully compatible with the extreme high-temperature operating environments of the Middle East region.
