BRAKE DISC (PAIR) DF4156

TRW DF4156 Brake Disc (Pair)

The TRW DF4156 brake disc is a high‑performance, ventilated front wheel braking component designed for a wide range of Suzuki models, including the Grand Vitara and Vitara series. Manufactured by TRW Automotive, this disc pair delivers reliable stopping power while maintaining durability under demanding driving conditions.

Key Features

• Ventilated Design: The dual‑channel ventilation system enhances heat dissipation, reducing brake fade during prolonged use.
• High‑Grade Material: Constructed from a premium alloy that offers excellent wear resistance and consistent performance across temperature variations.
• Precision Machining: Each disc is machined to tight tolerances, ensuring optimal fitment and balanced rotation for smooth braking.
• Compatibility: Specifically engineered for Suzuki Grand Vitara (both first‑generation and second‑generation) and Vitara models, covering a range of engine sizes from 1.6L to 2.0L.
• Coated Surface: The disc surface is treated with a high‑friction coating that improves brake pad adhesion and extends component life.

Technical Specifications

Installation Notes

The DF4156 pair is designed for straightforward installation. Technicians should follow standard procedures: remove the wheel and existing brake assembly, clean the hub surface, install the new discs with the supplied mounting hardware, and torque all fasteners to manufacturer specifications. Proper alignment of the disc relative to the caliper ensures even pad wear.

Performance Benefits

• Consistent Braking: The ventilated design keeps operating temperatures lower, maintaining brake fluid performance and preventing fade during spirited driving or heavy traffic.
• Extended Life: High‑grade alloy construction resists cracking and warping, extending the service life of both the disc and accompanying pads.
• Improved Safety: Reliable stopping power contributes to overall vehicle safety, especially in emergency braking scenarios.

Maintenance Recommendations

Regular inspection is advised. Look for signs of excessive wear, glazing, or scoring on the disc surface. Replace the pair if pad wear reaches the minimum thickness threshold or if any irregularities are observed that could compromise braking performance.

Compatibility Summary

The TRW DF4156 brake discs are specifically engineered for Suzuki front wheel assemblies, covering a broad range of model years and configurations. Their design ensures seamless integration with existing caliper systems without the need for additional modifications.

Conclusion

The TRW DF4156 Brake Disc (Pair) offers a blend of high performance, durability, and precise engineering tailored to Suzuki vehicles. Its ventilated construction, premium materials, and meticulous machining make it an ideal choice for drivers seeking reliable braking under all conditions.
