Passat B5 Front Brake Disc (312mm Vented)

This front brake disc is a high-quality replacement designed for Volkswagen Passat (3BG) models fitted with ATE braking systems and PR code 1LT. With a 312mm outer diameter and internally vented construction, this disc is intended for higher-powered Passat variants that require increased braking performance and improved heat management.

What this brake disc does

The front brake discs are the primary braking components on your Passat, responsible for converting vehicle speed into controlled stopping power. When the brake pedal is pressed, hydraulic pressure forces the brake caliper to clamp the pads against the disc faces. The resulting friction slows the vehicle safely and predictably.

This disc features an internally vented design, using internal cooling vanes to draw air through the disc as it rotates. This significantly improves heat dissipation during heavy braking, reducing brake fade, maintaining consistent pedal feel, and extending the service life of both discs and pads—especially important on heavier or more powerful Passat models.

Construction & specifications

• Outer diameter: 312mm

• Disc thickness: 25mm

• Brake disc type: Vented

• Surface finish: Coated (anti-corrosion protection)

• Stud pattern: 5-hole

• Fitting position: Front axle

• Manufacturer restriction: ATE

• PR code: 1LT

The protective coating helps prevent corrosion on non-friction surfaces, keeping the hub area cleaner and reducing the risk of the disc seizing to the hub over time.

Fitment & compatibility

Suitable for the following applications fitted with PR code 1LT and ATE front brakes:

• VW Passat (3BG) – 1.6, 1.8, 2.0 petrol and 1.9D, 2.0D, 2.3, 2.5D, 2.8 and 4.0 models

  • Production dates: 10/2000 – 11/2005

Always confirm the PR code, disc diameter (312mm), and ATE brake system before ordering, as smaller front brake setups were also fitted to some Passat B5/B5.5 models.

Recommended additional parts

For best braking performance and safety, we recommend fitting:

• Front brake pads compatible with ATE calipers and 312mm discs

• Brake disc retaining screws

• Brake pad fitting kit / anti-rattle clips (where applicable)

Front brake discs should always be replaced in axle pairs to ensure even braking and consistent pedal feel.
