TRW Automotive AfterMarket DF4240 Brake Disc

The TRW DF4240 Brake Disc is a high‑performance braking component designed for rear applications on a wide range of Nissan vehicles, including the Primera, Traveller, and various hatchback models. Engineered with precision machining and advanced materials, this disc delivers reliable stopping power, durability, and consistent performance across diverse driving conditions.

Key Design Features

• Material Composition: Constructed from a high‑strength alloy that offers excellent thermal conductivity, the DF4240 maintains optimal temperature during heavy braking, reducing fade and ensuring consistent performance.
• Diameter & Thickness: The disc measures 278 mm in diameter with a thickness of 10 mm, providing an ideal balance between weight and structural integrity for rear brake systems.
• Slotting Pattern: Features a carefully engineered slotting pattern that enhances heat dissipation while maintaining mechanical stability. The slots also facilitate efficient removal of debris and brake dust.
• Surface Finish: A smooth, factory‑applied finish reduces the risk of uneven wear when paired with compatible pads, extending overall component life.
• Compatibility: Designed to fit a broad spectrum of Nissan models from the late 1990s through early 2000s, including the Primera P11 (1.6 L, 1.8 L, 2.0 L) and Traveller variants.

Performance Characteristics

The DF4240 is engineered to provide:

• Consistent Braking Force: The disc’s uniform thickness and precise machining ensure even pad contact, translating into predictable braking performance.
• Heat Management: Advanced alloy composition coupled with slotting allows rapid heat dissipation, mitigating brake fade during prolonged or aggressive use.
• Longevity: The robust construction resists warping and cracking under thermal cycling, extending the service life of both the disc and associated pads.

Installation & Maintenance

Installing the DF4240 is straightforward for technicians familiar with rear brake systems. Key steps include:

1. Remove Existing Disc: Carefully detach the current rear disc, noting any retained hardware or alignment marks.
2. Inspect Rotors & Pads: Verify that rotors are free of damage and pads meet manufacturer specifications before installation.
3. Mount the DF4240: Secure the new disc onto the hub using the supplied bolts, ensuring torque is applied to spec for optimal alignment.
4. Reinstall Pads & Calipers: Fit compatible brake pads and reattach calipers, checking for proper clearance and pad wear indicators.
5. Brake Fluid Check: Verify fluid levels and perform a brake system bleed if necessary to eliminate air pockets.

Routine maintenance involves inspecting the disc surface for glazing or uneven wear. If significant wear is detected, replace the disc in conjunction with new pads to maintain braking efficacy.
