G4 Brake Disc - 280mm Vented

This 280mm vented front brake disc is a direct replacement part commonly fitted to VW Golf Mk4 (Golf IV) models equipped with the smaller factory front brake setup. Manufactured to original Volkswagen specifications, it provides dependable braking performance, effective heat control, and long service life, making it ideal for everyday road use and standard restorations.

With a 22mm thickness, 5-stud fixing, and protective coated finish, this disc is designed for precise fitment on vehicles using the 280mm front braking system.

This brake disc is most frequently used on VW Golf Mk4 models with lower to mid-range engine options that were not fitted with the larger 288mm or 312mm front brakes from the factory.

Fits VW Golf Mk4 (Golf IV):

• 1.4 Petrol

• 1.6 Petrol

• 1.8 Petrol (non-GTI / non-1.8T models)

• 2.0 Petrol

• 1.9 SDI Diesel

• 1.9 TDI Diesel

Not suitable for models factory-equipped with 288mm, 312mm, or larger performance brake systems. Always confirm disc diameter before ordering.

Why the 280mm Disc Was Used on Mk4 Golf

The 280mm vented disc was fitted to many Mk4 Golf variants as a balanced solution for everyday driving. The vented internal design allows airflow between the disc faces, helping to control heat build-up during braking and maintain consistent stopping performance under normal road conditions.

The coated surface protects against corrosion on non-friction areas, helping to keep hubs tidy and extend disc lifespan—especially important for vehicles used year-round or stored for extended periods.

Other Compatible Volkswagen Models

This front brake disc is also used on several other Volkswagen models that share the same braking specification:

• VW Bora (1998–2014) – 1.4, 1.6, 1.8, 2.0 petrol and 1.9 diesel variants

• VW New Beetle (1998–2010) – 1.4, 1.6, 1.8 petrol and 1.9 diesel models

• VW Fox II (2014–on) – 1.6 petrol

Brake setups can vary by year and engine; always verify disc size before purchase.

How This Brake Disc Works

When the brake pedal is applied, the caliper forces the brake pads against the rotating disc, converting vehicle speed into heat through friction. The vented design improves cooling by allowing air to circulate internally, reducing brake fade and helping preserve pad and disc life.

Recommended Additional Parts

For safe and effective braking, we strongly recommend replacing:

• Front brake pads

• Brake pad wear sensor (if fitted)

• Caliper carrier bolts (single-use on some models)

Brake discs should always be replaced in pairs across the axle to maintain even braking performance.
