Mk6 Polo Front Brake Disc (312mm Vented)

This 312mm front brake disc is a performance-grade replacement designed specifically for VW Polo Mk6 (AW/BZ) models fitted with PR code 1ZB. Commonly found on higher-powered variants, including 2.0 and 1.5 petrol models, this larger diameter disc provides increased braking torque and improved heat management compared to smaller front disc setups.

What this brake disc does

The front brake discs are the primary braking components on your Polo, responsible for converting vehicle speed into stopping power. When the brake pedal is pressed, hydraulic pressure forces the caliper to clamp the brake pads onto the disc face, creating friction that slows the vehicle.

With its 312mm diameter, this disc offers a larger swept area, allowing the brakes to generate more stopping force with less effort. The internally vented construction uses internal cooling vanes to pull air through the disc as it rotates, reducing heat build-up under hard braking. This helps prevent brake fade, improves pedal consistency, and supports confident braking during spirited driving or repeated heavy stops.

Construction & finish

  • Outer diameter: 312mm

  • Disc thickness: 25mm

  • Brake disc type: Internally vented

  • Surface finish: Coated (anti-corrosion protection)

  • Stud pattern: 5-hole

  • Fitting position: Front axle

The coated surface protects the non-friction areas of the disc from corrosion, helping to maintain a clean appearance behind alloy wheels and reducing the risk of the disc seizing to the hub over time.

Fitment & compatibility

Suitable for the following applications:

  • VW Polo Mk6 (AW/BZ) – 2.0 and 1.5 petrol models from 06/2017 onwards, PR code 1ZB only

Always confirm the PR code on your vehicle data sticker (boot floor or service book) before ordering, as 312mm discs are not interchangeable with smaller Polo front brake setups.

Recommended additional parts

For best results and safe installation, we recommend replacing:

  • Front brake pads matched to 312mm discs and PR code 1ZB

  • Brake disc retaining screws

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

Brake discs should always be replaced in pairs on the same axle to maintain even braking and balanced performance.
