TRW Automotive AfterMarket GDB3470 Brake Pad

TRW Automotive AfterMarket GDB3470 Brake Pad

The TRW GDB3470 is a high‑performance disc brake pad designed for the front axle of Subaru vehicles, including the Impreza Saloon and Estate models. Developed by TRW Automotive, this aftermarket component delivers reliable stopping power while maintaining durability under demanding driving conditions.

Key Features

• Optimized Friction Material: The pad incorporates a proprietary blend of ceramic and metallic fibers that provide consistent braking performance across a wide temperature range. This composition reduces fade during prolonged use, ensuring safe stopping distances even on steep descents.
• Low Noise & Vibration: Advanced engineering minimizes squeal and vibration, offering a quieter ride compared to many conventional brake pads.
• Extended Wear Life: The engineered compound resists wear, extending pad life by up to 20% over standard aftermarket options. This longevity translates into fewer replacements and lower maintenance costs.
• Heat Dissipation: Designed with a high‑thermal conductivity core, the GDB3470 dissipates heat efficiently, preventing brake fade and maintaining consistent performance during repeated hard braking.
• Compatibility: Specifically engineered for Subaru models such as the Impreza Saloon (2.5L) and Estate (2.5L), the pad fits seamlessly into the OEM mounting system without modification.

Installation Overview

Installing the TRW GDB3470 is straightforward for technicians familiar with front disc brake systems:

1. Remove Old Pads: Detach the existing brake pads from the caliper, ensuring no debris remains in the rotor surface.
2. Inspect Rotors: Check rotors for scoring or glazing; if necessary, perform a light resurfacing to guarantee optimal contact.
3. Install New Pads: Place the GDB3470 pads into the caliper bracket, aligning them with the mounting pins. Apply a thin layer of brake grease to the pad backing where it contacts the caliper piston.
4. Reassemble Calipers: Secure the caliper onto the rotor and tighten all fasteners to manufacturer specifications.
5. Bake‑In Process: After installation, perform a short drive to allow the pads to bed into the rotors. This step ensures maximum friction coefficient and longevity.

Performance Highlights

The TRW GDB3470 delivers:

• Consistent Braking Force: Maintains a stable braking feel across temperature swings, reducing the risk of sudden loss of control.
• Reduced Brake Fade: The high‑thermal conductivity core keeps pad temperatures lower during aggressive driving or heavy traffic.
• Quiet Operation: Advanced pad geometry and material composition minimize noise, enhancing overall vehicle comfort.

Compatibility Matrix

The TRW GDB3470 is specifically tailored for Subaru front disc brakes. Below is a concise compatibility list:

• Subaru Impreza Saloon (2.5L) – Front Axle
• Subaru Impreza Estate (2.5L) – Front Axle
• Subaru models with GDB3470‑designated calipers and rotors

For other vehicle makes or models, consult the manufacturer’s fitment guide before installation.

Maintenance Tips

• Inspect pads every 10,000 miles for wear; replace when thickness falls below 4 mm.
• Keep rotors clean to prevent scoring and ensure even pad contact.
• Avoid driving with the engine off on hot brakes to reduce heat buildup.
