TRW DF4409 Brake Disc

TRW DF4409 Brake Disc Overview

The TRW DF4409 Brake Disc is a high‑performance component designed to deliver reliable stopping power and durability for front-wheel drive vehicles, particularly the Hyundai Getz. Manufactured by TRW Automotive, this disc incorporates advanced engineering to meet demanding braking requirements while maintaining lightweight construction.

Key Design Features

• Ventilated Construction: The disc features a multi‑channel ventilation system that efficiently dissipates heat during heavy braking. This reduces the risk of brake fade and extends component life.
• Optimized Geometry: With a diameter of 256 mm and a thickness of 19 mm, the DF4409 balances strength with weight savings. The design includes a central bore that aligns with standard caliper mounting patterns.
• High‑Strength Steel Alloy: The disc is forged from a premium steel alloy that offers excellent wear resistance and maintains structural integrity under high temperatures.
• Surface Finish: A smooth, machined surface ensures consistent pad contact and reduces the likelihood of uneven wear or noise.

Compatibility and Application

The DF4409 is specifically engineered for front‑wheel applications in vehicles such as the Hyundai Getz. It matches the factory specifications for:

• Front caliper mounting points
• Bore size and offset
• Brake pad dimensions and clearance

Because of its precise fitment, the disc can be installed as a direct replacement or upgrade without requiring additional modifications.

Installation Guidelines

1. Preparation: Ensure the vehicle is securely lifted and supported. Remove existing brake discs and pads following standard safety procedures.
2. Cleaning: Clean all mounting surfaces with a solvent to remove grease, dust, or old brake fluid residue.
3. Mounting: Align the disc’s central bore with the caliper bracket. Secure it using the supplied bolts and torque specifications recommended by TRW.
4. Pad Installation: Install new brake pads that match the disc’s dimensions. Verify pad thickness to maintain proper clearance.
5. Bleeding: Bleed the braking system to eliminate air pockets, ensuring optimal hydraulic performance.
6. Testing: Perform a low‑speed test drive to confirm correct operation and listen for any abnormal noises.

Maintenance Tips

• Inspect the disc surface regularly for signs of glazing, scoring, or uneven wear. Replace if damage exceeds manufacturer guidelines.
• Keep the braking system clean; avoid contamination from road salts or debris that can accelerate corrosion.
• Use high‑quality brake fluid and change it according to the vehicle’s service schedule to preserve hydraulic integrity.

Performance Benefits

The TRW DF4409 delivers:

• Consistent stopping power even under repeated hard braking scenarios.
• Reduced heat buildup, minimizing brake fade during spirited driving or heavy traffic conditions.
• Longer service life compared to standard cast‑iron discs due to superior material properties.
