Bosch 0 986 479 B44 Brake Disc

The Bosch 0 986 479 B44 is a high‑performance, ventilated front brake disc designed for modern passenger cars. It delivers reliable stopping power while maintaining durability under demanding driving conditions.

Key Technical Specifications

• Diameter: 300 mm (11.81 in)
• Thickness: 24 mm (0.94 in)
• Material: Premium cast iron with a reinforced core for heat dissipation
• Ventilation: Internal venting system to reduce brake fade and improve cooling efficiency
• Surface Finish: Smooth, high‑friction coating optimized for ceramic or metallic pads
• Weight: Approximately 1.8 kg (3.97 lb) per disc
• Compatibility: Designed to fit a wide range of front wheel assemblies in vehicles such as Ford Mondeo, Jaguar X‑Type, and other models requiring a 300 mm ventilated disc.

Performance Highlights

The internal ventilation allows the disc to dissipate heat more effectively than solid discs. This reduces the risk of brake fade during prolonged use, such as in mountainous terrain or spirited driving sessions. The high‑friction surface ensures consistent braking performance across a variety of pad materials.

Installation Overview

Installing the Bosch 0 986 479 B44 involves the following steps:

1. Remove the existing front brake disc and caliper assembly.
2. Clean the hub surface with a solvent to remove any debris or old grease.
3. Place the new disc onto the hub, ensuring proper alignment of mounting holes.
4. Screw in the mounting bolts to the specified torque (typically 80–90 Nm).
5. Reinstall the caliper and brake pads, adjusting pad clearance as needed.
6. Bleed the brake system to eliminate air pockets and restore optimal hydraulic pressure.

Maintenance Tips

• Inspect the disc surface for glazing or uneven wear before each major service.
• Replace pads when pad thickness falls below 4 mm to maintain braking efficiency.
• Avoid using abrasive cleaners that could damage the high‑friction coating.
• Check bolt torque periodically, especially after heavy driving or towing activities.

Compatibility Summary

The disc is engineered to fit front wheel assemblies in a variety of vehicles. Common models include:

• Ford Mondeo (B5Y) – 2000‑2007
• Jaguar X‑Type – 2004‑2012
• Mondeo III Kombi and Stufenheck variants
• Other European passenger cars requiring a 300 mm ventilated front disc.
