BRAKE DISC (SINGLE) DF4983S

Overview of the BRAKE DISC (SINGLE) DF4983S

The DF4983S is a high‑performance, single front brake disc designed for use in a wide range of Nissan and Infiniti vehicles. Manufactured by TRW Automotive Aftermarket, this ventilated disc delivers superior stopping power, heat dissipation, and durability under demanding driving conditions.

Key Technical Specifications

• Diameter: 320 mm (12.6 in)
• Thickness: 28 mm (1.10 in)
• Material: Premium cast iron with a reinforced core for enhanced strength.
• Ventilation: Dual‑channel design to efficiently dissipate heat during braking.
• Surface Finish: Painted or anodized finish (varies by model) to resist corrosion and improve brake pad wear.
• Compatibility: Designed for Nissan Murano II, Murano I, Infiniti G‑Series (G25/G37/G35), and other models with the same wheel hub dimensions.

Design Features That Enhance Performance

The DF4983S incorporates several engineering features that set it apart from standard aftermarket discs:

• Optimized Ventilation Channels: The twin‑channel pattern reduces heat buildup, maintaining consistent brake performance even during prolonged or aggressive braking.
• Reinforced Core: A thicker core provides structural integrity, minimizing warping and extending the life of both the disc and the brake pads.
• Precision Machining: Tight tolerances ensure a perfect fit on the hub, reducing vibration and noise during operation.
• Corrosion‑Resistant Coating: The protective paint or anodized layer guards against rust in harsh climates, preserving aesthetic appeal and functional reliability.

Installation & Compatibility

Installing the DF4983S is straightforward for technicians familiar with front brake systems. Key steps include:

1. Remove Existing Disc: Detach the current brake disc, ensuring all bolts and fasteners are properly documented.
2. Inspect Hub & Caliper: Verify that the hub bore matches the 320 mm diameter and that the caliper is compatible with a single disc setup.
3. Mount the Disc: Align the disc with the hub, secure it using the supplied mounting bolts, and torque to manufacturer specifications.
4. Reinstall Calipers & Pads: Fit new or existing brake pads onto the caliper, ensuring proper clearance for the ventilated design.
5. Bleed Brakes: Perform a full bleed cycle to eliminate air from the hydraulic system and achieve optimal braking response.

Performance Benefits

The DF4983S delivers noticeable improvements in several critical areas:

• Stopping Power: Enhanced friction coefficient provides quicker, more reliable stops.
• Heat Management: Ventilation reduces the risk of brake fade during high‑speed or downhill driving.
• Longevity: Durable construction means fewer replacements over the vehicle’s lifetime.
• Noise Reduction: Smooth surface finish and precise machining lower squeal and rattling.

Applications & Vehicle Models

The DF4983S is tailored for a variety of models, ensuring that drivers receive the same level of performance across different platforms. Common applications include:

• Nissan Murano (first and second generation)
• Infiniti G‑Series (G25, G37, G35)
• Other Nissan/Infiniti vehicles with matching wheel hub specifications

Maintenance Tips

To keep the DF4983S operating at peak performance:

• Regular Inspection: Check for signs of wear, glazing, or scoring on the disc surface.
• Brake Pad Replacement: Replace pads when they reach the minimum thickness to avoid contact with the disc rim.
• Clean Thoroughly: Remove brake dust and debris using a non‑abrasive cleaner; avoid harsh chemicals that could damage the protective coating.
• Avoid Overheating: When driving in mountainous terrain or during spirited driving, allow brakes to cool between hard stops.

Why Choose the DF4983S?

The combination of advanced ventilation, reinforced core, and precise engineering makes the DF4983S a top choice for drivers who demand reliable braking performance. Whether you’re navigating city streets or tackling challenging roadways, this brake disc provides confidence and safety.

Conclusion

In summary, the BRAKE DISC (SINGLE) DF4983S is a meticulously engineered component that delivers exceptional stopping power, heat dissipation, and durability. Its compatibility with popular Nissan and Infiniti models ensures that it can be seamlessly integrated into existing brake systems, offering drivers enhanced safety and performance without compromising on quality.
