Front Brake Discs for LADA 112

Those engaged in Russian automotive parts wholesale know that the classic LADA 112 hatchback remains widely used in Russia, Eastern Europe, and Southeast Asia, resulting in consistently high demand for front brake disc replacements. Our OE-21103501070 brake disc is a specialized replacement component specifically designed for the LADA 112's front braking system, strictly compliant with original factory specifications. It requires no installation modifications and fits perfectly with original calipers and wheel hubs – a compatibility verified through extensive real-world testing. This brake disc utilizes high-carbon gray cast iron HT250, with carbon content precisely controlled between 3.2% and 3.5%. Compared to standard gray cast iron, it exhibits superior resistance to high-temperature deformation and thermal cracking, ensuring stable braking performance even during continuous downhill driving or frequent braking applications. Whether for daily commutes or long-distance suburban trips, it delivers smooth, linear braking response. While primarily compatible with all years of the LADA 112 (2112) hatchbacks, this OE-21103501070 disc also fits the front wheels of LADA 110 sedans and 111 station wagons on the same platform. Additionally, considering the vehicle's weight and suspension characteristics, we have optimized its dynamic balance parameters for enhanced performance. When installed this way, even during high-speed braking, the steering wheel is less likely to shake, and the driving feel will be closer to that of a new vehicle at the factory.

The surface treatment of this Lada 112 front brake disc involves three distinct steps, each specifically addressing key performance issues-a crucial aspect indeed.

Step 1: Zinc-based phosphating primer application: First, shot peening is used to remove surface oxide layers, followed by thorough degreasing and cleaning with alkaline solution before performing zinc-based phosphating treatment to form a dense phosphorus film on the metal surface. In essence, this process establishes a robust foundation for the paint layer, significantly enhancing adhesion and preventing issues such as blistering or patchy paint detachment over prolonged use.

Step 2: Apply cathodic electrophoretic primer for protection. Immersing the entire disc in an aqueous electrophoretic paint bath ensures full coverage of all hard-to-reach areas-including installation hole walls and ventilation gaps-through the electrophoretic effect. The primer thickness is precisely maintained at 8–12 μm, delivering optimal rust prevention. Third-party salt spray testing confirms that our OE-21103501070 Lada 112 brake disc can resist red rust formation on non-friction surfaces for up to 500 hours, performing reliably even in coastal humid environments or winter road salting conditions without requiring removal due to severe corrosion.

Step 3: Advanced weather-resistant topcoat finish upgrade: Apply an additional layer of gray rust-proof paint to non-friction areas, significantly enhancing scratch resistance and aging resistance. The brake friction surfaces are CNC precision-ground to completely remove the coating, revealing the original cast iron working surface for stable friction coefficient from the outset without requiring extended break-in time. Friction surface roughness is controlled at Ra ≤ 1.6 μm, ensuring smooth contact with brake pads and eliminating any harsh noises during braking when accelerating.

Quality control is implemented in strict accordance with the IATF16949 standard through three inspection stages. First, every batch of incoming raw materials undergoes spectral analysis and hardness testing; production only commences when the hardness remains steady between HB180 and HB220. Second, first article validation and hourly spot checks are carried out during machining, with focused monitoring of disc lateral runout and thickness variation. Third, 100% full inspection is performed on finished products, with dynamic balance controlled at ≤5g·cm, lateral runout ≤0.05mm, and circumferential thickness difference ≤0.03mm. Non-conforming products are directly scrapped or reworked and will never be released to the market.

Random samples from each product batch are sent to third-party laboratories for testing compliant with the ECE R90 standard. After 300 high-temperature braking cycles, no visible cracks appear on the disc surface, and the brake performance fade rate is lower than 15%, fully meeting market access requirements for the European Union.

Is this brake disc with part number OE-21103501070 only compatible with the Lada 112?
Answer: OE-21103501070 is the original OEM part number for the front brake disc of the Lada 112. Its core dimensions are specially calibrated for the Lada 112 hatchback model, and it is also compatible with the front axles of the Lada 110 sedan and Lada 111 station wagon built on the same platform. However, for shops that mainly supply replacement parts for the Lada 112, we highly recommend this specially calibrated brake rotor, which has undergone targeted optimizations for dynamic balance and heat dissipation, earning better feedback from vehicle owners after installation.

Are there any parameter requirements for installation when replacing the front brake disc OE-21103501070 on a Lada 112?
Answer: When installing this front brake disc for the Lada 112, tighten the wheel mounting bolts in diagonal increments. The final tightening torque is recommended to be 98Nm. Do not fully tighten a single bolt at once, as this may deform the disc surface under stress, resulting in excessive lateral runout and brake shudder at high speeds. In addition, remove rust and debris from the wheel mounting surface before installation to ensure full, flat contact with the disc.

At what level of wear does the Lada 112 brake disc OE-21103501070 need to be replaced?
Answer: The brand-new thickness of this Lada 112 front brake rotor is 19.5mm, and the industry-standard wear limit thickness is 18mm, meaning the maximum allowable wear on each side is 0.75mm. It is advised to replace the disc promptly when the total wear reaches 1.5mm; otherwise, braking performance and heat capacity will be compromised, leading to potential brake shudder or even cracking under high-speed braking conditions.

What model of front brake pads is the best match if purchasing the OE-21103501070 brake disc?
Answer: For the OE-21103501070 brake disc fitted to the front axle of the Lada 112, the factory-spec front brake pads with OEM part number 2110-3501080 are recommended. Their friction area perfectly matches the disc surface for stable brake torque output. For customers seeking performance upgrades, semi-metallic or ceramic brake pads of identical dimensions are also fully compatible without causing caliper interference.

Hello fellow overseas buyers! Today, we'd like to share two crucial updates on recent industry policies to help you prepare your stock inventory in advance and avoid potential regulatory pitfalls. The first update concerns the much-discussed EU "EU 7" emission regulations, which will take effect for all new vehicle models starting November 2026. This regulation introduces a groundbreaking requirement: it now strictly controls particulate matter emissions from braking systems. Specifically, PM10 particles generated by passenger car brake wear must not exceed 7 mg per kilometer, with even stricter limits of 3 mg per kilometer for pure electric vehicles. To meet these requirements proactively, we've developed brake discs for the Lada 112 model (OE number 21103501070) with optimized material formulations and specially engineered friction surface textures. When paired with suitable low-dust brake pads, these discs effectively reduce particulate emissions and ensure compliance ahead of schedule. With this solution, you won't face challenges from unsold inventory due to sudden policy changes. The second update involves the revised ECE R90 standards, which impose stricter requirements: aftermarket replacement parts must match original factory components exactly, while imposing more rigorous testing criteria for brake disc dimensions, thermal performance, and wear resistance. Rest assured, all our Lada series brake discs-including model OE-21103501070-are manufactured using precise 1:1 casting processes that replicate original factory specifications. Each batch undergoes rigorous comparative testing to ensure complete compliance with consistency standards, effectively preventing customs clearance delays. Finally, I'd like to share three practical tips for store owners and repair shop operators to avoid common pitfalls when purchasing Lada 112 brake discs: First, prioritize the OE number over just the vehicle model when verifying compatibility. Brake disc specifications may vary slightly across different years and configurations; always confirm the OE number is 21103501070 – this serves as the most reliable reference standard, significantly reducing returns caused by component mismatches. Second, identify quality through surface details: examine non-friction surfaces first – well-applied paint should be uniform, smooth, and fully covering edges; tactilely, high-quality cast iron feels smooth without pores or defects. Use measuring tools to check end face runout – discs with values below 0.05 mm typically exhibit no braking vibration after installation, minimizing after-sales complaints. Third, replace brake pads simultaneously when changing brake discs. If you install brand-new OE-21103501070 brake discs but use old brake pads, the wear patterns on the old pads simply won't match those of the new discs, leading to abnormal noises and uneven wear. Replacing brake discs with matching pads not only extends service life but also enhances braking performance, ultimately delivering a significantly better user experience.
