TRW Automotive AfterMarket DF4223 Brake Disc

TRW Automotive AfterMarket DF4223 Brake Disc

The TRW Automotive AfterMarket DF4223 Brake Disc is a high‑performance braking component engineered for the Mercedes-Benz A‑Class (W168) and Vaneo models. Designed to replace original equipment, it delivers reliable stopping power while maintaining the vehicle’s safety standards.

Key Technical Specifications

• Diameter: 258 mm – a size that matches the factory specifications for optimal fitment.
• Thickness: 8 mm – providing sufficient material for heat dissipation and durability.
• Material Composition: Advanced cast iron alloy with a reinforced core, ensuring structural integrity under high thermal loads.
• Surface Finish: Smooth, factory‑grade finish that promotes even brake pad wear and reduces noise.
• Mounting Type: Standard disc mounting with integrated cooling slots for efficient heat management.

Compatibility Overview

The DF4223 is specifically engineered to fit the following Mercedes-Benz platforms:

• A‑Class (W168) – models ranging from 1997 to 2005, including variants such as A190, A160, and A170.
• Vaneo (414) – the compact MPV that shares the same braking architecture as the A‑Class.

All installations are designed for the rear wheel assembly, ensuring seamless integration with existing brake calipers and hardware.

Performance Benefits

• Consistent Stopping Power: The disc’s engineered geometry provides uniform contact across the pad surface, reducing the likelihood of uneven wear.
• Heat Dissipation: Cooling slots and material composition allow rapid heat transfer away from the braking surface, minimizing fade during prolonged use.
• Longevity: The robust alloy construction resists cracking and warping, extending service life even under demanding driving conditions.
• Noise Reduction: Smooth finish and precise machining result in quieter operation compared to aftermarket alternatives.

Installation Highlights

Installing the DF4223 is straightforward for technicians familiar with standard brake disc replacement procedures. Key steps include:

1. Remove existing discs and inspect calipers for wear or damage.
2. Clean mounting surfaces to ensure proper torque application.
3. Align the new disc with the wheel hub, ensuring no gaps between the disc and the brake pad.
4. Tighten bolts to manufacturer specifications using a calibrated torque wrench.
5. Reinstall brake pads and perform a brake system bleed if necessary.

Quality Assurance

The DF4223 undergoes rigorous testing at TRW’s manufacturing facilities, including:

• Dimensional Accuracy Checks to guarantee fitment across all compatible models.
• Thermal Cycling Tests that simulate real‑world braking scenarios.
• Material Hardness Verification ensuring consistent performance under load.
