G4 Brake Disc - 228mm Vented

This 288mm vented front brake disc is a direct-replacement brake disc designed to original Volkswagen specifications and is most commonly fitted to the VW Golf Mk4 (Golf IV) range. It provides dependable stopping power, excellent heat dissipation, and long service life, making it ideal for daily drivers, restored cars, or performance-maintained vehicles.

With a 25mm thickness, 5-stud mounting, and protective coated finish, this disc is suited to vehicles equipped with the factory 288mm front brake setup.

This brake disc is widely used across the VW Golf Mk4 platform, fitted to many petrol and diesel variants that left the factory with 288mm vented front brakes.

Fits VW Golf Mk4 (Golf IV):

• 1.6 Petrol

• 1.8 Petrol

• 1.8 Turbo (1.8T)

• 2.0 Petrol

• 1.9 SDI Diesel

• 1.9 TDI Diesel

• 2.3 V5

• 2.8 V6 (non-R32 models)

Not suitable for models fitted with smaller 256mm brakes or larger performance systems such as 312mm or R32 brakes. Always confirm disc diameter before ordering.

Why This Disc Is Ideal for the Mk4 Golf

The Mk4 Golf places significant braking demand on the front axle, particularly on heavier or higher-powered models such as the 1.8T, V5, and V6. The vented design allows airflow between the disc faces, improving cooling under repeated braking and reducing brake fade — especially useful for motorway driving, spirited road use, or urban stop-start conditions.

The coated surface helps prevent corrosion on non-friction areas, keeping hubs and wheels cleaner and extending the life of the disc when the car is used year-round.

Other Compatible Volkswagen Models

In addition to the Golf Mk4, this disc is also used on several related Volkswagen platforms that share the same front brake specification:

• VW Bora (1998–2014)

•  VW New Beetle (1998–2010)

• VW Polo 9N (selected models)

• VW Polo 6R (selected models, check disc size)

How the Brake Disc Works

When braking, the caliper clamps the brake pads onto the rotating disc, converting motion into heat through friction. The internal ventilation channels allow heat to escape efficiently, helping maintain consistent braking performance and reducing stress on pads, discs, and brake fluid.

Recommended Additional Parts

For correct installation and best braking performance, we recommend fitting:

• New front brake pads

• New caliper carrier bolts (where specified by VW)

• Brake pad wear sensor (if fitted)

Brake discs should always be replaced in axle pairs to avoid uneven braking.
