TRW Automotive AfterMarket DF4184 Brake Disc

The TRW DF4184 is a high‑performance, ventilated front brake disc designed for a wide range of modern passenger vehicles. Engineered with advanced carbon‑reinforced technology, it delivers superior stopping power, heat dissipation, and long‑term durability.

Key Technical Features

• Diameter: 266 mm – a standard size that fits most compact and mid‑size cars.
• Thickness: 22 mm – balances strength with weight savings.
• Ventilation: Multi‑channel design ensures rapid cooling, reducing brake fade during heavy use.
• Carbon Reinforcement: High‑carbon content improves thermal stability and extends service life.
• Bore Size: 108 mm – compatible with a wide range of caliper pistons.
• Weight: Approximately 2.5–3 kg per disc, offering a lightweight alternative to cast iron.

Material Composition and Manufacturing Process

The DF4184 is fabricated from a proprietary alloy of aluminum and carbon fibers. The manufacturing process involves:

1. Precision Casting: High‑temperature molds create the disc’s core shape.
2. Carbon Fiber Integration: Layers of carbon fiber are embedded during cooling to reinforce structural integrity.
3. Heat Treatment: Controlled annealing optimizes hardness and reduces internal stresses.
4. Surface Finishing: A thin, high‑friction coating is applied to enhance pad contact and reduce wear.

Performance Advantages

• Enhanced Heat Dissipation: The ventilated design allows air to flow through the disc, maintaining lower operating temperatures even during aggressive driving.
• Reduced Brake Fade: Consistent temperature control ensures reliable braking performance over extended periods.
• Lightweight Construction: Lower unsprung mass improves vehicle handling and fuel efficiency.
• Longer Service Life: Carbon reinforcement resists wear, extending the interval between replacements.
• Compatibility: Fits a broad spectrum of models from Peugeot, Citroën, Opel, and related brands, making it a versatile choice for mechanics and enthusiasts alike.

Installation Guidelines

Proper installation is critical to maximize the disc’s performance. Follow these steps:

1. Remove Old Disc: Use a brake caliper tool to retract pistons before removing the old disc.
2. Clean Surfaces: Thoroughly clean the hub and new disc with brake cleaner to eliminate grease or debris.
3. Check Alignment: Ensure the disc is centered on the hub; misalignment can cause uneven pad wear.
4. Tighten Fasteners: Use a torque wrench to secure mounting bolts to manufacturer specifications.
5. Re‑insert Caliper Pistons: Carefully push pistons back into place, ensuring no damage to seals.
6. Brake Fluid Check: Verify fluid levels and top up if necessary before testing.

Maintenance Tips

• Regular Inspection: Check for cracks, warping, or excessive wear every 10,000 km.
• Pad Compatibility: Use high‑quality brake pads that match the disc’s friction coefficient to avoid premature wear.
• Avoid Overheating: During long descents or spirited driving, allow brakes to cool between hard stops.
• Proper Storage: Store discs in a dry environment to prevent corrosion of mounting surfaces.

Applications and Vehicle Compatibility

The DF4184 is engineered for front‑wheel braking systems on numerous models, including but not limited to:

• Peugeot 206/207/208/307/308 series
• Citroën C2/C3/C4/DS3/DS4/Xsara Picasso
• Opel Corsa F, Crossland X (P17), and related models
• Vauxhall/Dongfeng variants sharing the same chassis architecture
• Various commercial and passenger vehicles that require a 266 mm ventilated disc

These applications demonstrate the DF4184’s versatility across different brands while maintaining consistent performance standards.
