TRW Automotive AfterMarket DF4487S Brake Disc

TRW Automotive AfterMarket DF4487S Brake Disc

The TRW Automotive AfterMarket DF4487S Brake Disc is a high‑performance, ventilated brake disc designed for rear applications in a wide range of premium vehicles. Engineered with advanced carbon‑enhanced steel, this component delivers superior heat dissipation and consistent stopping power even under the most demanding driving conditions.

Key Design Features

• Ventilated Construction: Dual‑channel ventilation channels cut through the disc surface to expel heat efficiently, reducing brake fade during prolonged use.
• High‑Carbon Steel Alloy: The steel matrix is infused with a high carbon content, providing exceptional hardness and wear resistance while maintaining structural integrity.
• Precision Machining: Each disc is machined to strict tolerances, ensuring perfect fitment on the hub and optimal contact with brake pads.
• Corrosion‑Resistant Finish: A protective coating resists rust and corrosion, extending the life of the disc in varied climates.

Specifications

Vehicle Compatibility

The DF4487S is engineered to fit a broad spectrum of rear‑wheel vehicles, including:

• Volkswagen Touareg (model codes 7L6615601D, 7L8615601C, 95535240100, 95535240130, 95535240131)
• Audi Q7 (4LB) and other Audi models
• Porsche Cayenne (9PA, 92A) and related variants
• Skoda, Seat, and VW platforms sharing the same rear hub geometry
• Other OEMs that use the 330 mm diameter with a 130 mm hub bore

Because of its standardized dimensions and robust construction, the DF4487S is also popular in aftermarket applications where high‑performance braking is required.

Installation Notes

• Ensure the hub surface is clean and free from burrs before installation.
• Use a torque wrench to tighten the wheel bolts to the manufacturer’s specified sequence and torque value.
• After mounting, perform a brake system bleed to eliminate any trapped air in the hydraulic lines.
• It is recommended to replace both front and rear discs simultaneously for balanced braking performance.

Performance Benefits

The combination of ventilated design and high‑carbon steel yields several tangible advantages:

• Reduced Brake Fade: Efficient heat removal keeps the disc temperature within optimal limits, maintaining consistent braking force.
• Extended Service Life:
The hardened surface resists wear from brake pads, reducing the frequency of replacement.
• Improved Safety: Reliable stopping power in emergency situations enhances overall vehicle safety.

Maintenance Tips

• Inspect discs regularly for signs of glazing or uneven wear.
• Clean the disc surface with a non‑abrasive brake cleaner to remove dust and debris.
• Avoid using metal shavings or abrasive materials that could damage the vented channels.
