TRW df6601s Brake Disc

TRW DF6601S Brake Disc – Premium Performance for BMW

The TRW DF6601S Brake Disc is engineered to deliver exceptional stopping power and durability for a wide range of BMW models, including the 3 Series (F30, F31, F34, F36), 4 Series (F32, F33, F82, F83), and touring variants. Designed with advanced materials and precision manufacturing, this disc is the ideal choice for drivers who demand reliable braking under all conditions.

Key Features

• Diameter: 345 mm – a balanced size that provides optimal heat dissipation while maintaining compactness for tight wheel wells.
• Thickness: 24 mm – engineered to withstand high temperatures without warping, ensuring consistent performance during spirited driving or heavy braking.
• Ventilated Design: The disc incorporates a series of radial and cross‑flow vents that allow hot air to escape, reducing brake fade and maintaining peak friction.
• Split (Fissured) Pattern: A carefully engineered split pattern enhances heat transfer and reduces the risk of cracking under extreme loads.
• High Carbon Content: The rotor’s composition includes a high percentage of carbon, which improves thermal conductivity and extends service life.
• Two‑Piece Construction: Each disc is manufactured as a single unit but can be paired with the corresponding front or rear brake system for balanced braking performance.

Compatibility Overview

The DF6601S is specifically tailored to fit the following BMW models and variants:

• BMW 3 Series: F30, F31, F34, F36 (including Touring, Gran Turismo, and Coupe)
• BMW 4 Series: F32, F33, F82, F83 (including 435d xDrive and 420i variants)

These discs are available in both left‑hand drive (LHD) and right‑hand drive (RHD) configurations to accommodate global markets.

Performance Benefits

• Consistent Braking: The ventilated, split design ensures that heat is efficiently dissipated, preventing brake fade during prolonged use or high‑speed driving.
• Enhanced Durability: High carbon content and precise machining reduce wear on brake pads, extending the life of both the disc and the pads.
• Improved Safety: Reliable stopping power in wet or dry conditions enhances overall vehicle safety, especially during emergency maneuvers.

Installation Guidelines

1. Preparation: Remove the wheel and brake caliper. Clean the rotor surface with a non‑abrasive cleaner to remove any debris or old brake fluid residue.
2. Alignment Check: Verify that the rotor is free of warping by measuring its flatness with a dial indicator. If deviations exceed 0.1 mm, consider machining or replacing the disc.
3. Mounting: Secure the rotor to the hub using the supplied mounting bolts. Tighten in a star pattern to ensure even pressure distribution.
4. Caliper Reassembly: Position the caliper over the new rotor, ensuring that the brake pads are correctly seated and not rubbing against the disc surface.
5. Brake Fluid Check: After reassembling, bleed the braking system to remove any trapped air. Verify fluid levels and inspect for leaks.

Maintenance Tips

• Inspect the rotor surface every 10,000 km or after significant braking events for signs of glazing or scoring.
• Replace brake pads when pad wear indicators show less than 2 mm of pad material remaining to maintain optimal contact with the disc.
• Avoid using abrasive cleaners that can damage the rotor’s finish; opt for mild, non‑corrosive solutions instead.
