TRW Automotive AfterMarket DF4213 Brake Disc

TRW Automotive AfterMarket DF4213 Brake Disc

The TRW DF4213 brake disc is a high‑performance braking component engineered for the rear axle of BMW 3 Series Compact models, including the E36 generation (316, 318, 323). Designed with precision machining and advanced material composition, this disc delivers consistent stopping power, durability, and resistance to heat buildup under demanding driving conditions.

Key Features

• Material Composition: High‑strength cast iron alloy reinforced with a proprietary blend of carbon and silicon for optimal thermal conductivity and wear resistance.
• Diameter & Thickness: 272 mm outer diameter, 9.9 mm thickness, providing a robust surface area that balances weight and braking efficiency.
• Heat Dissipation: Integrated venting design enhances airflow across the disc surface, reducing brake fade during prolonged use.
• Surface Finish: Smooth, matte finish reduces dust accumulation and improves pad contact uniformity.
• Compatibility: Specifically engineered for BMW 3 Series Compact models (E36) with rear wheel sizes ranging from 14.6 in to 16 in, ensuring a perfect fit without modification.

Technical Specifications

Performance Highlights

The DF4213’s advanced venting and material blend provide consistent braking performance even under high‑temperature conditions. Its precise machining ensures a flat, uniform surface that maximizes pad contact, reducing the likelihood of uneven wear or vibration during hard braking.

• Heat Management: The disc’s venting architecture allows rapid heat dissipation, mitigating brake fade and maintaining stopping power over extended periods.
• Durability: High carbon content enhances resistance to cracking and warping, extending the lifespan of both the disc and accompanying pads.
• Noise Reduction: The matte finish minimizes dust buildup, which can contribute to squealing or rattling noises during operation.

Installation Guide

1. Preparation: Ensure the vehicle’s rear brake system is fully cooled. Remove the wheel and existing disc using a suitable socket set and torque wrench.

2. Inspection: Check the caliper mounting bolts for wear or damage. Replace any compromised components before installing the new disc.

3. Mounting: Align the DF4213 with the caliper bracket, ensuring that the bolt holes match precisely. Secure the disc using the original mounting bolts and torque to manufacturer specifications.

4. Pad Installation: Install compatible brake pads (recommended TRW or OEM) onto the calipers, aligning them correctly with the new disc surface.

5. Final Checks: Verify that the wheel rotates freely and that there is no binding. Reinstall the wheel and torque all lug nuts to spec.

Maintenance Tips

• Regularly inspect brake pads for wear; replace when pad thickness falls below 3 mm.
• Clean the disc surface with a non‑abrasive cleaner to remove dust and debris, preventing uneven pad contact.
• Check for any signs of warping or cracking after heavy braking sessions; if detected, consider replacing the disc immediately.
