Rear Brake Disc Of VOLVO XC40

This brake disc is manufactured from high-carbon alloy cast iron – a material inherently harder and more wear-resistant than conventional cast iron, enabling it to withstand greater pressure and impact. It features a competitive-grade directional grooving design; these grooves effectively remove debris and moisture generated during brake pad friction, keeping the contact surface clean. This ensures an immediate braking response – where the brakes engage instantly upon pressing the pedal – significantly enhancing braking force and efficiency, making the entire braking process feel more powerful and smoother. Regarding heat dissipation, its unique structural design combined with the material's properties allows heat to be rapidly dissipated from the friction zone, resulting in exceptional thermal performance. This effectively prevents thermal degradation that can occur during prolonged or high-intensity braking; even under heavy-load conditions – such as when the vehicle is fully loaded and braking frequently – the performance and stability of the braking system remain reliably guaranteed. Additionally, the brake disc generates minimal noise during operation, making daily driving quieter and more comfortable. Its high wear resistance, combined with a specially treated anti-rust surface, ensures exceptional durability; even in harsh environments – such as rain, snow, or exposure to de-icing agents – its service life is significantly extended. For installation, this product fully complies with original equipment manufacturer (OEM) specifications and is designed as a direct replacement part – requiring no additional modifications or specialized tools, making the installation process simple and quick. Its excellent compatibility ensures seamless integration with the vehicle's system; it is suitable for a range of Volvo models, including the XC40, offering owners a convenient and reliable option for upgrading or replacing their existing brakes.

This brake disc adopts a special three-layer electrostatic high-temperature spraying process exclusively for automotive brake discs, which is different from low-cost single-layer paint and simple sprayed products available on the market. All operations are carried out in a dust-free enclosed spraying workshop, ensuring no dust or impurities adhere to the paint surface. It comprehensively enhances the durability and appearance of the paint finish, making it suitable for harsh road conditions in Northern Europe characterized by high humidity, abundant de-icing salt, frequent rain and fog:

Core practical advantages of the spraying process: The full-area spraying is applied to non-friction surfaces only, so the braking performance of the friction working surface remains unaffected. The disc will not develop extensive rust quickly after long-term outdoor parking or driving in rainy seasons. It can withstand humid environments during transportation and storage without frequent additional anti-rust maintenance. Compared with original brake discs with thin paint layers, its salt spray resistance of the paint is increased by 60%. There will be no edge paint peeling or spreading rust after long-term use. Meanwhile, the inner side of the wheel rim looks neater, matching the premium exterior texture of Volvo vehicles perfectly.

This genuine Volvo rear brake disc of equivalent specifications (Rear Brake Disc of VOLVO XC40 31471477) is specially designed for the Volvo XC40 urban SUV, suited for daily commuting, wet and slippery roads in rainy and snowy weather, as well as harsh road conditions in Northern Europe featuring low temperatures and extensive use of de-icing agents. All Volvo models come standard with an active safety automatic braking system, which frequently triggers short-distance emergency braking during regular driving. The rear brake discs are constantly exposed to alternating hot and cold conditions. Compared with brake discs for ordinary family cars, this product demands higher overall thermal stability, better resistance to disc surface deformation and comprehensive anti-rust and anti-corrosion performance. 

Warranty Instructions
We provide a manufacturer's warranty of 80,000 kilometers or 12 months (whichever comes first) for the Rear Brake Disc of VOLVO XC40 31471477. This product is designed and verified in compliance with the original OE specifications of Kia and Hyundai. The warranty covers casting defects (including porosity, sand inclusions and shrinkage porosity) and abnormal peeling of the surface anti-rust coating that occur under normal operating conditions.

Please note that the warranty does not cover uneven wear, vibration and abnormal noises caused by improper installation. Such issues include excessive runout of the disc surface resulting from uncleaned hub bearing flange surfaces, slight deformation of the disc due to failure to fasten bolts in batches with standard torque, and running-in the new disc directly with worn-out brake pads that have reached the wear limit.

Shipping and Logistics
The it is shipped directly from our factory in Shandong. Each two discs are packed as one set. They are tightly wrapped with OPP foam and placed in customized thick cardboard boxes, with cross-shaped honeycomb partitions inside to avoid collision during transit.

The standard production and lead time is 30 to 45 working days after order confirmation. For urgent orders, expedited air freight can be arranged, and the additional air freight cost shall be borne by the buyer. We also accept designated freight forwarders if notified in advance.

After-sales and Return & Exchange Policy

After verification, you may choose to receive a replacement immediately or get a full refund.
- Manufacturing Quality Issues: For problems such as casting pinholes, quenching cracks and excessive dynamic imbalance, we will cover all round-trip freight and provide free replacements.
- Non-quality Related Returns and Exchanges: If returns or exchanges are needed due to incorrect model selection or incompatibility with the vehicle model, the buyer shall bear the return freight. Relevant procedures will be completed within 5 working days after the returned products are received and inspected.

Q1: When driving my XC90 fully loaded with seven people on a long downhill section in rainy weather, I feel unsure about the braking performance. Can this solid brake disc handle the load effectively?

A: The XC90 itself has a considerable curb weight, and with seven passengers on board, sustained downhill driving poses a severe challenge to any standard single-piece solid brake disc of original equipment size. However, the model 31471477 boasts core advantages: GG25 high-carbon grey cast iron features high heat capacity, and its zinc-aluminum coating ensures stable heat exchange performance. During continuous braking, it can greatly mitigate brake fade and prevent instantaneous vaporization of the resin in friction materials. It is recommended to use engine compression braking (manual downshifting) when driving downhill with a heavy load, allowing the brake disc a few seconds to cool down. This combined operation will greatly boost your driving confidence.

Q2: My S60 makes a sharp squeaking noise from the rear wheels when turning at low speeds or reversing with a cold engine. Does this mean the brake discs are worn out completely?

A: In nearly all cases, the noise is caused by hard metal particles in the brake pad compound sliding across the thin layer of surface rust on the cold brake disc. The squeak will disappear after applying the brakes firmly once. If a persistent metal scraping sound occurs after off-roading or rainy days, please inspect the brake discs in person. If your fingernail can feel grooves deeper than 0.5 millimeters, or there are rust pits over 1 millimeter deep on the disc surface, do not attempt repairs and replace the brake discs immediately.

Q3: How often should the rear brake discs of a Volvo be inspected generally?

A: For vehicles mainly driven on paved roads, conduct the inspection along with routine maintenance every 20,000 kilometers. For owners of XC60 or XC90 who frequently travel on unpaved roads, it is advised to shorten the inspection interval to every 15,000 kilometers. Pay close attention to the following three key aspects:
• Critical limit: Check if the actual thickness of the brake disc is below the minimum limit of 9 millimeters.
• Surface damage: Look for radial deep cracks, hard spots or extensive rust areas on the disc surface.
• Smoothness: Accelerate the vehicle to over 80 kilometers per hour, then gently apply the brakes. Check if there is obvious intermittent vibration transmitted to the steering wheel and brake pedal.
