TRW DF4311 Brake Disc

TRW DF4311 Brake Disc – Premium Front Ventilated Performance

The TRW DF4311 Brake Disc is a high‑performance front brake disc engineered for the Mitsubishi Colt VI, Smart Forfour, and related models. Designed with advanced metallurgy and precision machining, this component delivers reliable stopping power while maintaining durability under demanding driving conditions.

Key Features & Design Highlights

• High‑Carbon Steel Construction: The disc is forged from a high‑carbon steel alloy that offers excellent heat resistance and structural integrity. This material choice ensures consistent braking performance even during prolonged or aggressive use.
• Ventilated Architecture: Integrated cooling channels allow air to flow through the disc, effectively dissipating heat generated during braking. The result is reduced brake fade and improved overall safety.
• Optimized Thickness & Diameter: With a diameter of 281 mm and a thickness that balances strength with weight savings, the DF4311 provides a stable platform for brake pads while minimizing unsprung mass.
• Precision Machining: Each disc is machined to tight tolerances, ensuring perfect fitment on the hub and consistent pad contact. This precision reduces vibration and extends component life.
• Surface Finish & Coating: The outer surface features a smooth finish that promotes even pad wear. A protective coating resists corrosion and maintains aesthetic appeal over time.

Compatibility & Vehicle Fitment

The DF4311 is specifically engineered for the following models, ensuring optimal performance and fitment:

• Mitsubishi Colt VI (Z3_A, Z2_A) – 2005‑2012
• Smart Forfour (454) – 2005‑2006
• Colt CZC Convertible – 2006‑2009
• Mitsubishi Smart – various years within the same platform family

All models share a common front hub design, allowing the DF4311 to be used interchangeably across these vehicles without modification.

Performance Benefits

• Consistent Braking: The high‑carbon steel core maintains structural integrity at elevated temperatures, preventing warping and ensuring reliable stopping power.
• Heat Management: Ventilation reduces thermal buildup, mitigating brake fade during extended driving or heavy traffic conditions.
• Reduced Unsprung Weight: The disc’s lightweight construction improves handling dynamics by lowering the mass that moves with each wheel.
• Longer Pad Life: Even wear across the disc surface translates to more uniform pad consumption, extending the interval between replacements.

Installation Guidelines

1. Remove Existing Disc: Use a brake caliper tool or impact driver to detach the current disc. Keep all hardware for reassembly.
2. Inspect Hub & Calipers: Verify that the hub surface is clean and free of burrs. Check caliper pistons for proper operation.
3. Align Disc: Place the new DF4311 onto the hub, ensuring it sits flush against the mounting surface.
4. Tighten Bolts: Secure the disc with the supplied bolts, tightening to the manufacturer’s torque specification (typically 70 Nm).
5. Reinstall Calipers: Fit the caliper over the new disc and reattach using the original hardware.
6. Brake Fluid Check: Verify fluid levels and top up if necessary. Bleed the brakes to remove any air pockets.

Maintenance & Care Tips

• Regularly inspect brake pads for wear; replace when pad thickness falls below manufacturer’s minimum.
• Clean the disc surface with a non‑abrasive cleaner to prevent contamination that could affect braking performance.
• Avoid using high‑temperature brake fluid or additives that may degrade the disc material.
• Store vehicles in a dry environment to reduce corrosion risk on the disc’s protective coating.
