TRW Brake Disc Single Vented

TRW Brake Disc Single Vented – The Pinnacle of Performance and Reliability

The TRW DF6617S brake disc is engineered to deliver uncompromised stopping power for the BMW 5 Series (F10/F11) and compatible models. Designed as a single, vented component, it combines advanced metallurgy with precision machining to meet the demanding requirements of modern automotive braking systems.

Key Technical Specifications

• Diameter: 330 mm – optimal for high-performance brake calipers and pad assemblies.
• Thickness: 20 mm – provides a robust structural profile while maintaining manageable weight.
• Ventilation: Dual-vented design – ensures efficient heat dissipation during aggressive driving or heavy braking scenarios.
• Material Composition: High‑carbon alloy steel – offers superior hardness, wear resistance, and thermal stability.
• Compatibility: BMW 5 Series (F10/F11), including Touring and Limousine variants; suitable for models equipped with 2.0 L four‑cylinder engines.

Engineering Excellence

The DF6617S is crafted using a high‑carbon steel matrix, which undergoes meticulous heat treatment to achieve a fine-grained microstructure. This process results in:

• Enhanced wear resistance: Extends the lifespan of both the disc and accompanying brake pads.
• Superior thermal conductivity: Rapidly transfers heat away from the braking surface, reducing fade during sustained use.
• Consistent dimensional stability: Maintains precise tolerances across temperature variations, ensuring reliable fitment.

Ventilation Design for Optimal Heat Management

The dual-vented architecture incorporates strategically placed channels that allow hot air to escape from the disc’s interior. This design:

• Prevents excessive temperature buildup, which can compromise braking performance.
• Reduces the risk of brake pad glazing by maintaining a cooler operating environment.
• Supports high-speed driving conditions, such as track use or spirited road driving.

Installation and Fitment

Installing the TRW DF6617S is straightforward for technicians familiar with BMW 5 Series brake systems. Key points include:

• Removal of existing discs: Use a torque wrench to loosen caliper bolts, then carefully lift the disc away from the rotor.
• Cleaning: Remove all debris and old brake fluid residue before mounting the new disc.
• Alignment: Ensure the disc is seated evenly on the hub; use a torque wrench to tighten bolts to manufacturer specifications.
• Brake pad compatibility: Pair with matching TRW or OEM pads for optimal performance and longevity.

Performance Benefits

The DF6617S delivers noticeable improvements in braking feel and consistency:

• Consistent stopping power: Maintains reliable deceleration across a wide range of speeds.
• Reduced brake fade:
The vented design keeps temperatures lower, preserving pad performance during repeated stops.
• Enhanced safety:
Reliable braking translates to better vehicle control in emergency situations.

Durability and Longevity

Thanks to its high‑carbon composition and precise machining, the DF6617S offers a long service life. Even under demanding conditions—such as spirited driving or heavy traffic—the disc maintains structural integrity and performance.

Compatibility with BMW 5 Series Variants

The disc is specifically engineered for:

• BMW 5 Series (F10) – Limousine models from 2010 to 2016.
• BMW 5 Series (F11) – Touring models from 2009 to 2017.

It is also suitable for vehicles equipped with the 2.0 L four‑cylinder engine, ensuring a seamless fit across the BMW 5 Series lineup.

Why Choose TRW?

TRW has long been recognized as a leader in automotive braking solutions. The DF6617S exemplifies this reputation through:

• Rigorous quality control: Each disc undergoes multiple inspections to guarantee dimensional accuracy and material integrity.
