ThisSSANGYONG ACTYON 4840134101 Rear Brake Disc, is tailor-made for Ssangyong Korando (CK) series vehicles. It fully complies with original factory design standards and serves as a reliable safety guarantee for your daily urban commutes and light off-road trips on weekends. We adopt GG25 high-carbon alloy cast iron, the same material used by original manufacturers. Each product goes through strict metallographic structure analysis and mechanical property tests to deliver excellent thermal stability and thermal deformation resistance.

Unlike the commonly used ventilated brake discs on the front axles, the solid rear brake discs are made of a single piece of cast iron with no ventilation grooves in the middle. This design simplifies the manufacturing process, cutting costs and reducing unsprung mass. Anyone who has driven Ssangyong vehicles will know that a lighter rear axle contributes to better handling. Additionally, since the front brake discs of most Ssangyong models bear the majority of the braking load, solid rear brake discs are more than sufficient for regular use.

Quality Control System
Qualified brake disc factories have generally established a comprehensive quality management system. Inspections start right after raw materials are received. Electric furnace material tests and spectral analysis for chemical composition are conducted, and unqualified raw materials are rejected and will not proceed to the next production process.
During production, every finished brake disc undergoes a series of inspections after coming off the production line. Premium manufacturers carry out nearly 20 inspection procedures for each product and implement 100% full dynamic balance testing throughout the process. Specifically, every unit of 4840134101 is tested on dynamic balance machines. Any product that fails the test will be reworked or scrapped immediately and will not be delivered to customers.

Processing Equipment and Technology
Most modern brake disc production lines are fully or semi-automated. Robotic arms for loading and unloading, automatic processing lines and automatic inspection lines are widely adopted in major brake disc industrial clusters across Shandong, Hubei, Hebei and other regions.

For instance, some factories have achieved full automation and intelligent operation covering all procedures from raw blank feeding to finished product packaging, including blank treatment, dynamic balance testing, precision surface machining, high-temperature painting (including Dacromet coating lines), quality inspection and packaging.
For our model 4840134101, the key processing requirements are as follows:
- Precision turning of inner and outer diameters as well as thickness, with tolerances kept within specified ranges
- Accurate drilling of mounting holes and central holes to avoid excessive deviation
- Flatness and surface roughness of friction surfaces meeting relevant standards
- Dynamic balance calibration to prevent vibration during high-speed rotation

Export Standards and Qualifications
Many Chinese brake disc manufacturers have obtained the qualification of "National Automotive Parts Export Base Enterprise". Their products are sold to major markets such as Europe and America, complying with local quality and environmental protection regulations. Access to these markets is proof that the products have passed rigorous reviews.
In terms of supply capacity, leading brake disc manufacturers boast an annual output of over 10 million units, ensuring stable and on-time order delivery.

Tips on Origin Selection
The model 4840134101 available on the market comes from various origins. Some are manufactured in Shandong, a major cluster for brake disc production. Some are produced in Hebei, which is also home to numerous brake disc manufacturers, while others are imported from South Korea. As a key export base for brake discs in China, Shandong features a solid industrial foundation and a well-established quality control system. Buyers are advised to check the product origin when placing orders, as the origin usually reflects the overall quality level of the products.

A multi-layer protection solution is uniformly adopted for packaging to prevent the iron trays from being bumped and scratched during long-distance transportation. The standard production and delivery lead time is 25 to 40 working days after order confirmation. Customers may designate their own freight forwarders. Sea transportation is recommended to keep shipping costs down given the moderate weight of each item. Express air freight can be arranged for urgent orders, with additional fees charged based on actual expenses incurred.

The SSANGYONG ACTYON 4840134101 Rear Brake Disc comes with a manufacturer's quality warranty valid for 100,000 kilometers or 12 months. The warranty covers casting defects (such as blowholes and pinholes formed during casting) and surface treatment defects (including coating peeling and abnormal rusting).

Specifically: If casting-related defects like cracks and blowholes appear on the disc surface within the warranty period, or the Dacromet coating peels off abnormally and severe rust occurs under normal service conditions, you may apply for after-sales service.

Response Time
If customers need to resolve quality issues, they shall submit photos of the brake disc taken from all angles (close-up shots showing the defective areas are preferred) along with the original order information. Upon receiving the complete application documents, we promise to provide a solution within 48 hours, and customers may choose product replacement or a refund based on actual circumstances. This 48-hour commitment is calculated based on working days and will be extended on weekends and statutory holidays.

Additionally, please note that abnormal wear of the brake disc caused by failure to replace or maintain other components of the braking system (such as brake pads and calipers) in a timely manner is not covered under the warranty.

Q: Are part numbers 4840134101 and 4840134100 interchangeable?

A: Yes. These two part numbers refer to the same brake disc with identical dimensions and specifications. They are just different codes assigned by different suppliers. Either number is acceptable when making a purchase.

Q: The brake disc has worn down to 8.4 mm. Can it still be used?

A: Strictly in accordance with safety standards, 8.4 mm is the minimum wear thickness specified by the manufacturer. At this thickness, the brake disc no longer has sufficient heat capacity and structural strength. Continuing to use it will pose a risk of brake failure, so it is recommended to replace it immediately.

Q: Is the rear brake disc with part number 4840134101 compatible with all model years of Ssangyong Korando?
A: This brake disc is mainly suitable for Ssangyong Korando (CK) models manufactured from 2013 to 2019. For Korando vehicles of other years or variants, please provide your vehicle VIN so we can confirm the compatibility.

Industry Trend: Escalating Environmental Standards
It has become an irreversible global trend for the auto parts industry to embrace environmental protection. Traditional zinc/chromium-containing coating processes are being gradually restricted. Regulations including the EU REACH Regulation and ELV Directive have imposed stricter controls on chemical substances. Currently, many Chinese brake disc exporters have adopted copper-free eco-friendly formulas combined with advanced high-temperature stability technologies, and all performance indicators fully comply with European environmental access standards. If you plan to sell products to the European market, make sure to verify the relevant compliance certificates during procurement.

China's Global Role in the Brake Disc Industry
China's brake disc industry has achieved rapid development in recent years. While small and medium-sized manufacturers focus on small orders and cost-effective products, major export-oriented enterprises can steadily supply mid-to-high-end markets in Europe and America. Every brake disc undergoes nearly 20 rigorous inspections before leaving the factory, including 100% full inspection for dynamic balance. Full traceability from raw materials to finished products has become a standard practice. Purchasers' trust in "Made in China" brake discs keeps growing.
