TRW Automotive AfterMarket DF4856S Brake Disc

The TRW DF4856S brake disc is a high‑performance, ventilated rotor designed for front application on a wide range of Lexus and Toyota models. Engineered with advanced carbon‑enhanced steel, it delivers exceptional heat dissipation, consistent braking force, and long‑term durability even under demanding driving conditions.

Key Technical Features

• Diameter: 334 mm (13.1 in)
• Thickness: 30 mm (1.18 in)
• Material Composition: High‑carbon steel alloy with a proprietary heat‑resistant coating
• Ventilation: Dual‑channel design for optimal airflow and temperature control
• Weight: Approximately 2.5 kg (5.5 lb) per disc, reducing unsprung mass
• Compatibility: Front left/right on Lexus IS II/III, GS, RC; Toyota LEXUS models 200‑460 series (2005–2011)
• Installation: Standard mounting pattern with 4 bolt holes; compatible with OEM and aftermarket calipers

Performance Advantages

The DF4856S rotor’s carbon‑rich steel matrix offers a higher modulus of elasticity, which translates into reduced flex under high braking loads. Combined with the ventilated design, this ensures:

• Consistent Fade Resistance: Maintains braking performance during prolonged deceleration or spirited driving.
• Improved Heat Dissipation: Dual‑channel vents allow hot air to escape efficiently, keeping the rotor temperature within safe limits.
• Reduced Unsprung Mass: Lighter weight improves suspension response and vehicle handling.
• Longer Life Span: The high‑carbon coating resists corrosion and wear, extending service intervals.

Installation & Maintenance Tips

1. Preparation: Clean the rotor surface with a brake cleaner to remove oils or residues. Inspect for any manufacturing defects such as cracks or unevenness.
2. Alignment: Use a torque wrench to tighten mounting bolts to the manufacturer’s specified sequence and torque value, ensuring even pressure distribution.
3. Brake Pad Compatibility: Pair with high‑performance brake pads that match the rotor’s thermal capacity for optimal braking feel.
4. Break‑In Procedure: Perform a controlled break‑in by applying moderate brakes at low speeds, gradually increasing intensity to allow pad material to conform to the rotor surface.
5. Inspection Schedule: Check rotor thickness and surface integrity every 10,000 km (6,200 mi) or as part of routine maintenance. Replace if wear exceeds manufacturer limits.

Applications Across Vehicle Models

The DF4856S is specifically engineered for the following vehicle platforms:

• Lexus IS II (GSE2, ALE2, USE2) – front left/right
• Lexus IS III – front left/right
• Lexus GS – front left/right
• Lexus RC – front left/right
• Toyota LEXUS series (200‑460 models, 2005–2011) – front application

Its universal fitment across these models makes it a versatile choice for both OEM replacements and aftermarket upgrades.
