TRW Automotive AfterMarket DF4007 Brake Disc

TRW Automotive AfterMarket DF4007 Brake Disc is a high‑performance braking component engineered to deliver reliable stopping power and durability for a wide range of Toyota models, including the Starlet, Paseo, and Tercel. Designed with precision machining and advanced material technology, this brake disc offers superior heat dissipation, reduced wear, and consistent performance under demanding driving conditions.

Key Features

• Optimized Ventilation: The DF4007 incorporates a dual‑channel venting system that efficiently channels heat away from the braking surface, maintaining optimal temperature during heavy braking or prolonged use.
• High‑Grade Cast Iron Construction: Manufactured from premium cast iron with a carefully balanced alloy composition, the disc provides excellent structural integrity and resistance to cracking under high stress.
• Precision Machining: Each disc is machined to exact tolerances, ensuring a perfect fit on the hub and rotor assembly. This precision reduces vibration and enhances overall braking feel.
• Corrosion‑Resistant Finish: A protective coating resists rust and corrosion, extending the life of the brake system even in harsh environmental conditions.
• Compatibility: The DF4007 is specifically engineered for front axle applications on Toyota models such as the Starlet (P8/P9), Paseo L5, and Tercel. It matches OEM specifications for diameter, thickness, and bolt pattern.

Installation Guidelines

Installing the DF4007 brake disc is straightforward for technicians familiar with front axle replacement. Follow these steps to ensure optimal performance:

1. Remove the Wheel and Brake Caliper: Safely lift the vehicle, remove the wheel, and detach the caliper from the rotor.
2. Detach the Old Disc: Use a torque wrench to loosen the mounting bolts. Carefully slide the old disc off the hub.
3. Clean the Hub Surface: Remove any debris or residue with a clean rag and ensure the surface is smooth for proper seating.
4. Install the New Disc: Position the DF4007 onto the hub, aligning the bolt holes. Tighten the mounting bolts to the manufacturer’s specified torque sequence.
5. Reattach the Caliper and Wheel: Secure the caliper back onto the rotor, reinstall the wheel, and lower the vehicle.
6. Brake System Check: Pump the brake pedal a few times to seat the pads against the new disc. Verify that there are no leaks or abnormal noises.

Performance Benefits

The DF4007 is engineered to provide:

• Consistent Braking Response: The precise machining and balanced design reduce vibration, delivering a smooth and predictable braking feel.
• Enhanced Heat Management: Dual‑channel ventilation keeps the disc cooler during intense braking sessions, preventing fade and maintaining stopping power.
• Longer Service Life: The high‑strength cast iron material resists wear and deformation, extending the interval between replacements.
• Improved Safety: Reliable performance under various driving conditions ensures that the vehicle stops safely when needed.

Maintenance Tips

To keep the DF4007 brake disc in optimal condition:

• Inspect for cracks or uneven wear during routine service checks.
• Keep the braking system clean; avoid oil, grease, and other contaminants on the rotor surface.
• Replace brake pads when they reach the minimum thickness to prevent glazing of the disc.
• Use a calibrated torque wrench for all mounting bolts to maintain proper clamping force.
