• Thickness: 32 mm (1.26 inches) at the outer rim, tapering to a 64.5 mm (2.54 inches) height from the hub.
• Weight: Approximately 3.8 kg per disc, optimized for balanced mass distribution.
• Material: High‑strength cast iron alloy with a reinforced steel core for enhanced heat dissipation.
• Ventilation: Internally vented design featuring a series of radial channels that promote airflow and reduce thermal buildup.
• Punching Pattern: Perforated surface (drilled holes) to further improve cooling efficiency and reduce weight.
• Bore Size: 112 mm (4.41 inches) compatible with the standard hub diameter of the W221 front axle.

Design Features & Performance Benefits

The disc’s internally vented architecture ensures that heat generated during braking is efficiently expelled, preventing brake fade and maintaining consistent performance. The perforated surface not only reduces overall weight but also creates turbulence in the airflow, enhancing cooling capacity.

Its precision machining guarantees a flat, even surface for optimal contact with brake pads, reducing vibration and noise during operation. The disc’s reinforced steel core provides structural integrity, allowing it to withstand high temperatures without warping or cracking.

The VAICO V30-80011 is specifically engineered for the Mercedes-Benz S‑Class (W221) front axle. It matches the original equipment specifications, ensuring a seamless fit with existing brake calipers and hardware. The disc’s 112 mm bore size aligns perfectly with the hub diameter of the W221, eliminating the need for additional adapters or modifications.

Installation is straightforward: remove the old disc, clean the hub surface, apply anti‑seize compound to the mounting bolts, and secure the new disc using the supplied hardware. Torque specifications should follow the manufacturer’s guidelines to guarantee optimal performance and safety.

The core of the VAICO V30-80011 is a high‑strength cast iron alloy, chosen for its excellent wear resistance and ability to absorb shock loads. The disc undergoes a rigorous heat treatment process that enhances its hardness while maintaining toughness, ensuring it can endure repeated braking cycles without degradation.

During manufacturing, the disc is subjected to precision CNC machining, guaranteeing dimensional accuracy within ±0.05 mm. The perforation pattern is carefully engineered to balance weight reduction with structural integrity, preventing any compromise in braking performance.

The combination of internal venting and surface perforations creates a highly efficient thermal management system. By allowing hot gases to escape rapidly, the disc maintains lower operating temperatures, which translates into extended lifespan and consistent braking performance.

Additionally, the disc’s material composition resists corrosion and oxidation, even under harsh environmental conditions. This resilience ensures that the brake system remains reliable over many years of use.

The VAICO V30-80011 incorporates a smooth, flat surface finish that minimizes contact noise with brake pads. The internal venting also reduces vibration by allowing heat to dissipate evenly across the disc’s structure.

• Inspect for cracks or scoring every 10,000 km (6,200 mi) or after any high‑speed braking event.
• Check pad wear and replace pads when the remaining thickness is below 4 mm (0.16 inches).
• Clean the disc surface with a non‑abrasive cleaner to remove brake dust and debris.
• Verify that mounting bolts are torqued to the specified value; re‑torque if necessary after every replacement cycle.

While the VAICO V30-80011 is optimized for the W221 front axle, its dimensions and design make it suitable for other vehicles that share similar hub diameters and brake system configurations. However, compatibility should be verified with each specific model before installation.

The VAICO V30-80011 Brake Disc exemplifies engineering excellence tailored to the Mercedes-Benz S‑Class (W221). Its combination of internally vented design, perforated surface, high‑strength material, and precision manufacturing delivers superior braking performance, durability, and thermal management. Whether you’re restoring a classic sedan or upgrading an existing vehicle, this disc provides reliable stopping power that meets the rigorous demands of modern driving.
