TRW Automotive AfterMarket DF4308S Brake Disc

TRW Automotive AfterMarket DF4308S Brake Disc

The TRW DF4308S is a high‑performance, ventilated brake disc designed for front applications on Volkswagen vehicles such as the Transporter, Touareg, and Multivan. It features a 308 mm diameter with a 30 mm thickness, providing robust stopping power while maintaining lightweight characteristics.

Key Design Features

Ventilated Construction: The disc incorporates multiple internal cooling channels that dissipate heat efficiently during braking. This design reduces the risk of brake fade and ensures consistent performance in demanding driving conditions.

High‑Carbon Composite Layer: A carbon‑rich surface layer enhances friction coefficient, allowing for shorter stopping distances and improved durability under high‑temperature operation.

Optimized Rim Geometry: The rim is engineered to balance strength and weight. It offers a smooth transition between the disc face and the mounting flange, reducing vibration and noise during use.

Compatibility

• Volkswagen Transporter (7HA, 7HH, 7EA, 7EH)
• Volkswagen Touareg (7LA, 7L6, 7L7)
• Volkswagen Multivan (7HM, 7HN, 7HF, 7EF, 7EM, 7EN)
• Other VW models with the same front axle specifications

The disc is available in both left and right configurations, ensuring seamless installation on either side of the vehicle.

Installation Overview

1. Remove Existing Disc: Detach the brake caliper, then unscrew the mounting bolts to free the old disc.
2. Clean Surface: Use a brake cleaner and microfiber cloth to remove grease or debris from the hub area.
3. Mount New Disc: Align the disc with the hub, secure it using the supplied bolts, and torque to manufacturer specifications.
4. Reinstall Caliper: Position the caliper over the new disc, ensuring proper clearance. Tighten all fasteners evenly.
5. Brake Fluid Check: Verify fluid levels and bleed brakes if necessary to eliminate air pockets.

Performance Benefits

The combination of a ventilated design and high‑carbon surface delivers:

• Enhanced heat dissipation for sustained braking performance.
• Reduced brake fade during prolonged use or heavy traffic conditions.
• Improved stopping power with consistent pedal feel.
• Longer lifespan due to resistance against thermal cracking and wear.

Maintenance Tips

To preserve optimal performance:

• Inspect discs regularly for glazing, scoring, or uneven wear.
• Replace brake pads when pad thickness falls below the manufacturer’s minimum.
• Avoid driving on wet roads with worn brakes; consider a full braking system check if stopping distances increase.
