TRW Automotive AfterMarket DF4025 Brake Disc

Performance Advantages

The DF4025 rotor incorporates a precision‑machined surface that promotes even brake pad wear. Its design enhances:

• Heat Management: The finned architecture increases the rotor’s thermal capacity, reducing fade during prolonged braking.
• Brake Feel: A smoother, more consistent pedal response due to reduced vibration and noise.
• Longevity: Engineered for extended service life, even under aggressive driving or high‑temperature environments.

Installation & Compatibility Notes

Installing the DF4025 is straightforward for technicians familiar with front brake assemblies. Key points include:

• Use the original caliper mounting hardware to preserve alignment and torque specifications.
• Verify that the rotor thickness matches OEM tolerances; if necessary, adjust pad wear indicators accordingly.
• Ensure proper drainage clearance for brake fluid by maintaining the correct rotor spacing.
