• Diameter & Thickness: Standard 312 mm diameter with a 28 mm thickness, matching the original specifications for many Mercedes-Benz models.
• Weight Reduction: Lightweight construction reduces unsprung mass, improving vehicle handling and ride quality.
• Surface Finish: Smooth, high‑friction surface engineered to resist glazing and maintain consistent braking force over time.
• Compatibility: Designed for front axle applications on models such as the Mercedes-Benz E-Class (W211), CLS (C219), and other related platforms. The disc is available in single or paired configurations, depending on vehicle requirements.

Performance Benefits

The TRW DF4264 brake disc delivers a host of performance advantages that elevate both safety and driving experience:

• Consistent Braking Response: The engineered surface texture ensures reliable friction coefficients, providing predictable stopping distances.
• Heat Management: Ventilation channels dissipate heat rapidly, reducing the risk of brake fade during aggressive braking or high‑speed driving.
• Longevity: High‑quality materials and precise machining result in extended service life compared to standard aftermarket options.
• Reduced Noise & Vibration: The disc’s balanced design minimizes noise, vibration, and harshness (NVH) during operation.

Installation Overview

Installing the TRW DF4264 brake disc is a straightforward process that can be completed with standard automotive tools. Below is a step‑by‑step guide for technicians and DIY enthusiasts alike:

1. Safety First: Secure the vehicle on jack stands and disconnect the battery to prevent accidental airbag deployment.
2. Remove Wheel & Brake Caliper: Detach the wheel, then carefully remove the caliper by loosening the mounting bolts. Keep the caliper suspended using a hanger or cable to avoid stress on brake lines.
3. Extract Old Disc: Remove any retaining clips or screws that secure the disc to the hub. Gently tap the disc with a rubber mallet if it is stuck due to corrosion.
4. Clean Hub Surface: Use a brake cleaner and a soft brush to remove dust, grease, and old brake pad residue from the hub surface.
5. Install New Disc: Place the TRW DF4264 disc onto the hub, ensuring it sits flush against the mounting surface. Reattach any retaining clips or screws.
6. Reassemble Caliper & Wheel: Position the caliper over the new disc and secure it with bolts. Replace the wheel and torque the lug nuts to manufacturer specifications.
7. Brake Fluid Check: Inspect brake fluid levels and top up if necessary. Bleed the brakes to remove any air pockets, ensuring optimal hydraulic performance.

Maintenance Tips

To keep your TRW DF4264 disc performing at its best, follow these routine maintenance practices:

• Regular Inspection: Check for signs of wear such as uneven thickness, scoring, or glazing. Replace the disc if any of these issues are present.
• Brake Pad Compatibility: Pair the disc with high‑quality brake pads that match the disc’s surface characteristics to maintain optimal friction and reduce wear.
• Avoid Overheating: When driving in mountainous terrain or during spirited driving, allow brakes to cool between hard stops to prevent thermal degradation.
• Clean After Use: Remove brake dust buildup with a dedicated brake cleaner to preserve the disc’s surface integrity.
