9N Polo Front Brake Disc (239mm Vented)

This front brake disc is a direct-fit replacement for Mk4 Volkswagen Polo (9N) and Volkswagen Fox I models equipped with PR codes 1LM or 1ZN. Manufactured to original equipment dimensions, it features a vented design, 239 mm outer diameter, and 18 mm disc thickness, ensuring reliable braking performance and effective heat dissipation.

The disc is supplied with a protective coated surface, helping to prevent corrosion on the hub and outer edge while maintaining a clean appearance behind alloy wheels. This makes it ideal for both everyday use and long-term ownership.

What this brake disc does

The front brake disc provides the friction surface that the brake pads clamp against when braking. As the disc rotates with the wheel, friction converts the vehicle’s kinetic energy into heat, slowing the car safely and predictably.

How it works

This disc uses a vented internal vane design, allowing air to flow between the braking faces as the disc rotates. This improves cooling compared to a solid disc, reducing brake fade and maintaining consistent braking performance during repeated stops.

With an 18 mm thickness, the disc ensures correct pad alignment and caliper operation, while the 239 mm diameter matches the factory braking systems fitted to these PR-code applications.

Fitting notes & recommended additional parts

• Fitting position: Front axle (left and right discs are identical)

• Number of holes: 5 (5-stud hub pattern)

• Brake pads: Always replace brake pads when fitting new discs

• Brake discs: Supplied individually – replacing discs in axle pairs is strongly recommended

• Calipers & carriers: Inspect for wear or corrosion before refitting

• Brake fluid: Check condition during installation

Replacing front brake discs in pairs ensures balanced braking performance and helps prevent steering vibration or uneven wear.
