The TRW DF4821S is a high‑performance brake disc engineered for the Ford Transit Mk6 and related chassis models, including the flatbed and bus variants. Designed to meet stringent safety standards, this component delivers reliable stopping power under demanding conditions.

Key Technical Specifications

• Diameter: 280 mm (11 in.) – a size that balances braking efficiency with vehicle weight distribution.
• Thickness: 16 mm – ensures structural integrity while maintaining manageable mass for optimal heat dissipation.
• Hub Bore: 160 mm – compatible with the standard hub dimensions of Ford Transit Mk6 chassis.
• Material Composition: High‑strength cast iron alloy, treated to resist thermal fatigue and corrosion.
• Surface Finish: Smooth, factory‑polished surface that promotes consistent brake pad wear.

Compatibility Overview

The DF4821S is specifically tailored for the following Ford Transit configurations:

• Transit Mk6 Van (V347, V348, FA)
• Transit Mk6 Bus (V347, V348, FD, FB, FS, FZ, FC)
• Flatbed / Chassis 2.4 Tdci Post models

Its design aligns with the rear axle architecture of these vehicles, ensuring a seamless fit without the need for additional modifications.

Performance Highlights

• Enhanced Heat Dissipation: The cast‑iron construction and precise thickness allow rapid heat transfer, reducing brake fade during prolonged use.
• Consistent Wear Characteristics: The uniform surface promotes even pad contact, extending the life of both disc and pads.
• Durability Under Load: Engineered to withstand heavy-duty applications such as commercial transport and long-haul driving.

Installation Guidance

Installing the DF4821S follows standard procedures for rear brake discs on Ford Transit Mk6 models. Key steps include:

1. Secure the vehicle on a lift and remove the rear wheels.
2. Detach the existing disc by loosening the mounting bolts.
3. Align the new DF4821S with the hub bore, ensuring proper seating.
4. Tighten bolts to the manufacturer’s torque specifications.
5. Reinstall brake pads and perform a brake system bleed if necessary.

For detailed torque values and safety checks, consult the official Ford service manual or TRW technical documentation.

Quality Assurance & Compliance

• Manufactured in accordance with ISO/TS 16949 quality management standards.
• Complies with European Union regulations for automotive safety components.
• Subjected to rigorous testing, including thermal cycling and impact resistance tests.

Maintenance Tips

To preserve optimal braking performance:

• Inspect the disc surface regularly for glazing or scoring.
• Replace brake pads when wear indicators reach the minimum thickness threshold.
• Avoid driving with worn discs, as this can lead to uneven pad contact and reduced stopping power.
