TRW df4481s Brake Disc

TRW DF4481S Brake Disc

The TRW DF4481S Brake Disc is a high‑performance, full‑size disc designed for front and rear applications on a wide range of light commercial vehicles and passenger cars. It delivers consistent stopping power, excellent heat dissipation, and long service life under demanding operating conditions.

Key Features

• Material Composition: The disc is manufactured from a premium alloy steel blend that offers superior strength-to-weight ratio. This composition ensures the disc can withstand high temperatures without warping or cracking.
• Heat Dissipation: Integrated venting and drilled design allow rapid heat transfer, reducing brake fade during heavy use such as towing or highway cruising.
• Surface Finish: The outer surface is machined to a smooth finish that promotes optimal pad contact. This reduces noise and vibration while enhancing braking efficiency.
• Compatibility: Engineered for vehicles including Fiat, Peugeot, Citroën, Ducato, Honda Civic Vii (2001‑2005), and other models requiring the DF4481S specification. The disc fits both left and right side mounting positions.
• Dimensions: Standard diameter of 280 mm with a thickness that meets OEM requirements for robust performance. The bore size accommodates standard wheel hubs.
• Weight: Lightweight construction reduces unsprung mass, improving vehicle handling and ride quality.

Installation & Compatibility Details

The TRW DF4481S is designed for straightforward installation. It comes with a pre‑drilled mounting pattern that matches the factory hub layout on supported models. The disc’s backing plate includes a heat‑shielding layer to protect surrounding components.

• Front & Rear Mounting: Suitable for both front and rear brake systems, providing flexibility for replacement or upgrade scenarios.
• Vehicle Models: Commonly used on Fiat Ducato, Peugeot Boxer, Citroën Jumper, Honda Civic Vii (2001‑2005), and other vehicles that specify the DF4481S part number. The disc is also compatible with aftermarket brake kits that require a 280 mm diameter.
• Brake Pad Compatibility: Works seamlessly with TRW’s range of brake pads, ensuring optimal friction characteristics and wear balance.

Performance Characteristics

The disc’s design focuses on delivering reliable stopping power across a spectrum of driving conditions. Its high‑temperature tolerance allows it to maintain performance during prolonged braking sessions, such as steep descents or heavy load towing.

• Consistent Braking: The uniform thickness and precise machining guarantee even pad wear, reducing the likelihood of uneven brake fade.
• Noise Reduction: The smooth surface finish minimizes squeal and chatter, providing a quieter driving experience.
• Longevity: The alloy steel construction resists corrosion and fatigue, extending the disc’s service life even in harsh environments.

Maintenance Tips

To preserve optimal performance, follow these maintenance guidelines:

1. Regular Inspection: Check for cracks, scoring, or excessive wear during routine brake system inspections.
2. Pad Replacement: Replace brake pads when the pad thickness reaches the manufacturer’s minimum specification to avoid uneven wear on the disc.
3. Cleaning: Use a non‑abrasive cleaner to remove brake dust and debris. Avoid harsh chemicals that could damage the surface finish.
4. Heat Management: Ensure adequate airflow around the braking system, especially in heavy-duty or towing applications, to prevent overheating.
