TRW DF4155 Brake Disc

TRW DF4155 Brake Disc

The TRW DF4155 Brake Disc is a high‑performance braking component engineered for optimal safety and durability in modern vehicles. Designed with precision machining and advanced material science, this disc delivers reliable stopping power while resisting wear, heat buildup, and corrosion.

Key Features

• Ventilated Design: The disc incorporates a series of strategically placed ventilation channels that enhance airflow, reducing heat accumulation during heavy braking. This feature helps maintain consistent brake performance over extended periods.
• Painted Finish: A durable paint coating protects the metal surface from oxidation and environmental damage, ensuring long‑term visual appeal and structural integrity.
• Optimized Dimensions: With a diameter of 257 mm and a thickness of 17 mm, the disc offers an ideal balance between strength and weight. These dimensions are specifically tailored for vehicles such as the Suzuki Ignis, providing seamless fitment.
• High‑Grade Steel Composition: Manufactured from premium alloy steel, the disc resists cracking and deformation under high temperatures, guaranteeing consistent braking performance even in demanding driving conditions.
• Precision Machining: Each disc is produced with tight tolerances to ensure perfect alignment with brake calipers. This precision reduces vibration and noise during operation.
• Compatibility: The DF4155 model is engineered for front‑axle applications in a range of compact cars, offering reliable performance across multiple vehicle platforms.

Performance Benefits

The combination of ventilated architecture and high‑quality steel results in superior heat dissipation. This translates to reduced brake fade, meaning the brakes remain responsive even during prolonged or aggressive use. The painted surface also minimizes rust, extending the lifespan of the disc without compromising braking efficiency.

Installation Overview

Installing the TRW DF4155 Brake Disc is a straightforward process that follows standard vehicle maintenance procedures:

1. Remove the wheel and tire to expose the brake assembly.
2. Detach the caliper by loosening the mounting bolts, then carefully slide it away from the disc.
3. Unscrew the old disc using a suitable socket or wrench, taking care not to damage surrounding components.
4. Place the new DF4155 disc onto the hub, ensuring proper alignment with the mounting surface.
5. Reinstall the caliper, tightening bolts to manufacturer specifications.
6. Replace the wheel and tire, then perform a brake system check to confirm correct operation.

Maintenance Tips

• Regularly inspect the disc for signs of wear, such as uneven thickness or surface damage.
• Keep the braking system clean by removing dust and debris from the disc surface during routine maintenance.
• Use high‑quality brake fluid and replace it according to the vehicle’s service schedule to maintain optimal hydraulic performance.
