TRW Automotive AfterMarket DF4147 Brake Disc

TRW Automotive AfterMarket DF4147 Brake Disc

The TRW DF4147 is a high‑performance, ventilated brake disc designed for a wide range of Ford and Jaguar models, including the Mondeo III series (B5Y, B4Y, BWY) and X‑Type. Engineered with advanced carbon‑enhanced steel, this disc delivers superior heat dissipation, consistent braking force, and extended service life.

Key Design Features

• Ventilated Construction: Dual‑channel ventilation channels cut through the disc surface to expel heat efficiently, reducing brake fade during aggressive driving or heavy load conditions.
• High Carbon Content: The steel alloy incorporates a high percentage of carbon, which increases hardness and wear resistance while maintaining structural integrity under thermal stress.
• Optimized Geometry: A 300 mm diameter with a 24 mm thickness provides a balanced combination of stopping power and weight savings. The disc’s profile is engineered to match the brake caliper pistons of the supported models, ensuring proper fitment and seal integrity.
• Surface Finish: The outer rim features a smooth, polished finish that promotes even pad contact and reduces noise during operation.

Compatibility Overview

The DF4147 is specifically calibrated for the following vehicle families:

Each disc is manufactured to meet the exacting tolerances required by these models, ensuring seamless integration with existing brake systems.

Performance Benefits

• Consistent Braking: The ventilated design keeps pad temperature lower, maintaining friction coefficient and preventing sudden loss of braking force.
• Reduced Wear: High carbon steel resists surface wear, extending the life of both the disc and accompanying brake pads.
• Lightweight Construction: Compared to conventional cast iron discs, the DF4147 offers a weight reduction that improves vehicle handling dynamics.
• Noise Reduction: The smooth rim surface minimizes vibration and squeal during braking, enhancing overall ride quality.

Installation Guidelines

1. Remove the existing brake disc and caliper assembly following manufacturer safety procedures.
2. Inspect the hub for any damage or irregularities; clean thoroughly to remove debris.
3. Place the new DF4147 onto the hub, ensuring proper alignment with the mounting flange.
4. Secure the disc using the supplied bolts and torque specifications as per vehicle service manual.
5. Reinstall the caliper, re‑attach brake pads, and bleed the hydraulic system to eliminate air pockets.
6. Perform a test drive at low speed to confirm proper operation before resuming normal driving conditions.

Maintenance Tips

• Regularly inspect pad wear; replace pads when the remaining thickness reaches the minimum threshold specified by the vehicle manufacturer.
• Keep the disc surface free of oil, grease, and brake fluid contamination to avoid uneven wear.
• Use a calibrated torque wrench for all fastener installations to prevent loosening or over‑tightening.
• Monitor braking performance; any sudden changes in pedal feel may indicate pad or disc issues requiring inspection.
