TRW Automotive AfterMarket DF4022 Brake Disc

The TRW DF4022 is a high‑performance, front‑wheel brake disc designed for a wide range of Mitsubishi and Proton models. Engineered with precision machining and advanced material technology, this disc delivers reliable stopping power while maintaining durability under demanding driving conditions.

Key Features

• Ventilated Design: The disc incorporates a series of strategically placed cooling channels that dissipate heat efficiently, reducing brake fade during prolonged use.
• High‑Strength Steel Core: Constructed from a proprietary alloy, the core offers excellent resistance to warping and cracking.
• Optimized Surface Finish: The outer surface is engineered for optimal friction with brake pads, ensuring consistent braking performance.
• Standardized Dimensions: With a diameter of 236 mm and a thickness of 18 mm, the disc fits seamlessly into most front‑wheel assemblies for Mitsubishi Lancer, Carisma, Colt, and Proton models.
• Corrosion‑Resistant Coating: A protective paint layer guards against rust and environmental degradation, extending the life of the disc.

Compatibility Overview

The DF4022 is specifically tailored for the following vehicle families:

• Mitsubishi Lancer (1992–present)
• Mitsubishi Carisma (1996–2006)
• Mitsubishi Colt IV (1992–present)
• Proton Persona, Proton Wira, and other Proton models derived from Mitsubishi platforms
• Various trim levels including hatchback, sedan, and station wagon variants

Each model receives a pair of front discs, ensuring symmetrical braking and balanced handling.

Installation & Maintenance

Installing the DF4022 is straightforward for technicians familiar with standard brake systems:

1. Remove the existing front discs and calipers.
2. Clean the wheel hub and mounting surface to eliminate debris.
3. Align the new disc with the hub, ensuring proper seating of the mounting flange.
4. Reinstall the caliper and secure it with torque specifications recommended by TRW.
5. Perform a brake fluid flush and bleed to eliminate air from the system.

For optimal performance, replace brake pads concurrently with the disc. Regular inspections should focus on pad wear, disc surface integrity, and caliper function.

Performance Benefits

• Consistent Stopping Power: The ventilated design maintains lower operating temperatures, preventing brake fade during aggressive driving or heavy traffic.
• Enhanced Durability: The high‑strength core resists deformation, ensuring the disc maintains its shape and alignment over time.
• Improved Handling: Balanced front‑wheel braking contributes to stable vehicle dynamics, especially during cornering and emergency stops.
• Reduced Maintenance Costs: The disc’s longevity and resistance to corrosion reduce the frequency of replacement, saving time and money.
