G4 Rear Brake Disc (239mm Solid)

This 239mm solid rear brake disc is a high-quality replacement designed specifically for VW Golf Mk4 (Golf IV) models equipped with the factory rear disc brake system using this disc size. Manufactured to original VW specifications, it delivers reliable rear braking performance, long service life, and a clean factory appearance thanks to its protective coated finish.

With a 9mm thickness and 5-stud fixing, this disc is intended for vehicles identified by PR codes 1KE or 2EG.

Primary Fitment – VW Golf Mk4 (1997–2014)

This rear brake disc is most commonly fitted to VW Golf Mk4 models that were factory-equipped with rear disc brakes rather than drums.

Fits VW Golf Mk4 with PR Codes 1KE or 2EG:

• 1.8 Petrol

• 2.0 Petrol

• 2.3 V5

• 2.8 V6

• 1.9 Diesel (SDI / TDI)

PR codes can be found on the vehicle data sticker in the service book or boot area. Always confirm PR code and disc diameter before ordering, as Mk4 Golfs were available with multiple rear brake setups.

Why the 239mm Disc Is Used on the Mk4

The 239mm solid rear disc provides consistent braking force for the rear axle, supporting overall braking balance and vehicle stability. While the front brakes handle most of the stopping power, correctly functioning rear discs are essential for controlled braking, especially under heavy braking or when the vehicle is loaded.

The solid disc design is durable and well suited to everyday road use, while the coated surface helps prevent corrosion on non-friction areas, extending disc life and keeping the rear hubs looking tidy behind alloy wheels.

Other Compatible Volkswagen Models

This rear brake disc is also fitted to several closely related VW models that share the same rear brake specification:

VW Bora (1998–2014)

• Engines: 1.8, 2.0 petrol; 1.9 diesel; 2.3 V5; 2.8 V6

• PR Codes: 1KE or 2EG

VW Jetta III (2004–2010)

• Engine: 2.0 petrol

• PR Codes: 1KE or 2EG

How the Rear Brake Disc Works

When braking, the rear caliper clamps the brake pads onto the rotating disc, creating friction that slows the rear wheels. Although the rear brakes contribute less force than the fronts, they are vital for braking stability, even pad wear, and effective handbrake operation on disc-equipped vehicles.

RHD Fitment Notes

• Fitting position: Rear axle

• Suitable for both right-hand (driver’s side) and left-hand (passenger side) rear positions on RHD vehicles

Recommended Additional Parts

For best braking performance and safety, we recommend fitting:

• New rear brake pads

• Rear brake caliper fitting hardware (where required)

• New caliper carrier bolts if specified

Rear brake discs should always be replaced in axle pairs to ensure even braking and correct handbrake operation.
