TRW DF4407 Brake Disc

TRW DF4407 Brake Disc – Precision Engineering for Ford Tourneo & Transit

The TRW DF4407 Brake Disc is a high‑performance, OEM‑grade braking component specifically engineered for the rear axle of Ford’s popular commercial and passenger vans: the Tourneo Connect, Transit Connect, and related models from 2006 to 2013. Designed with rigorous automotive standards, this disc delivers consistent stopping power, durability, and ease of maintenance.

Key Technical Specifications

• Diameter: 278 mm (10.94 in)
• Thickness: 11 mm (0.43 in)
• Material Composition: High‑strength cast iron with a black anodized finish to resist corrosion and heat buildup.
• Heat Dissipation: Optimized internal geometry for rapid heat transfer, reducing brake fade during heavy use.
• Weight: Approximately 4.2 kg (9.3 lb) per disc – lightweight yet robust.
• Compatibility: Fits all rear wheel assemblies on Ford Tourneo Connect and Transit Connect models equipped with the P65, P70, P80 chassis variants, including 1.8 L petrol, 2.0 L diesel, and LPG/TDci powertrains.
• Installation: Standard mounting bolts (M12) with a torque specification of 120 Nm; compatible with existing caliper brackets and brake pads.
• Surface Finish: Smooth, machined surface for optimal pad contact; no burrs or sharp edges.

Performance Highlights

The DF4407 disc is engineered to meet the demanding braking requirements of commercial vehicles that often carry heavy loads. Its design ensures:

• Consistent Stopping Power: Even under high‑temperature conditions, maintaining brake performance.
• Reduced Brake Fade: Advanced heat management keeps pad temperature within optimal range.
• Long Service Life: High‑grade cast iron resists wear and corrosion, extending the interval between replacements.
• Quiet Operation: Smooth surface reduces noise during braking, enhancing driver comfort.

Installation Guide

1. Safety First: Secure the vehicle on a jack stand and disconnect the battery to prevent accidental air brake release.
2. Remove Old Disc: Use an impact wrench to loosen the caliper bolts, then slide the caliper away. Carefully remove the old disc from the hub.
3. Prepare New Disc: Inspect for scratches or damage; clean with a solvent if necessary.
4. Mount Disc: Place the new DF4407 onto the wheel hub, aligning the mounting holes. Tighten bolts to 120 Nm in a star pattern.
5. Reinstall Caliper: Slide the caliper back over the disc and secure with bolts. Re‑attach any brake lines or ABS components.
6. Bleed Brakes: Follow manufacturer’s procedure to remove air from the system, ensuring optimal braking feel.

Maintenance Tips

• Regular Inspection: Check for cracks or scoring on the disc surface during routine service intervals.
• Pad Compatibility: Pair with TRW’s DF4407 compatible brake pads to maintain optimal friction and avoid premature pad wear.
• Cleaning: Use a non‑abrasive cleaner; avoid harsh chemicals that could damage the anodized finish.
• Temperature Monitoring: In high‑load scenarios, monitor disc temperature with an infrared thermometer to preempt overheating.

Why Choose TRW DF4407?
