ABS 7173-S Brake Drum

Overview of the ABS 7173‑S Brake Drum

The ABS 7173‑S Brake Drum is a high‑performance braking component engineered for rear wheel applications on a wide range of Volkswagen models, including the classic Golf 2, Golf 3, and Golf 3 Variant. Designed with precision machining and advanced material selection, this drum delivers reliable stopping power, durability, and consistent performance under demanding driving conditions.

Design & Material Composition

The core of the ABS 7173‑S is constructed from a high‑strength steel alloy that offers excellent resistance to wear and heat buildup. The outer surface features a specialized coating that reduces friction, enhances dust dispersion, and prolongs the life of the brake lining.

Key design attributes include:

• Optimized internal geometry for efficient airflow, which helps dissipate heat during braking events.
• Precision-machined bore that ensures a snug fit within the wheel hub assembly.
Integrated mounting flange compatible with standard ABS rear brake assemblies.

Compatibility & Vehicle Integration

The ABS 7173‑S is engineered to fit seamlessly into the braking systems of numerous Volkswagen models. It is specifically tailored for:

• Volkswagen Golf 2, Golf 3, and Golf 3 Variant
Rear wheel assemblies requiring a standard drum brake configuration. Both left‑hand drive (LHD) and right‑hand drive (RHD) variants, ensuring global applicability.

Installation involves replacing the existing rear drum with the ABS 7173‑S, aligning it with the hub flange, and securing it using the supplied mounting hardware. The design ensures that all standard brake calipers and shoes are compatible without modification.

Performance Characteristics

The ABS 7173‑S delivers superior braking performance through a combination of material science and engineering precision:

• High heat tolerance – Capable of withstanding temperatures up to 650 °C without significant deformation.
• Consistent stopping power – Maintains uniform friction coefficients across a wide range of operating conditions, from light city driving to high‑speed highway braking.
Reduced brake fade – The enhanced airflow design mitigates heat buildup, preserving braking efficiency during prolonged use. Low noise and vibration – Smooth internal surfaces reduce rattling and produce a quieter braking experience.

Installation Guidelines

Installing the ABS 7173‑S is straightforward for technicians familiar with rear drum brake systems. Follow these steps to ensure optimal fitment:

1. Remove the existing rear wheel and brake assembly.
2. Detach the old drum from the hub flange, noting any retaining screws or clips.
3. Align the new ABS 7173‑S with the mounting flange, ensuring that the bore matches the hub’s inner diameter.
4. Screw the drum into place using the supplied hardware, tightening to manufacturer torque specifications.
5. Reinstall brake shoes and calipers, checking for proper clearance.
6. Reattach the wheel and perform a brake system bleed if necessary.

Maintenance & Longevity

To preserve the performance of the ABS 7173‑S, adhere to these maintenance practices:

• Regular inspection – Check for signs of wear, cracks, or surface irregularities during routine service intervals.
• Brake lining replacement – Replace brake shoes when pad material has worn down to 3 mm thickness.
Proper lubrication – Apply high‑temperature grease to the drum’s internal bearing surfaces as recommended by the manufacturer. Avoid excessive heat exposure – Use the vehicle within its intended operating limits; prolonged heavy braking can accelerate wear.

Technical Specifications

Conclusion

The ABS 7173‑S Brake Drum exemplifies engineering excellence in rear wheel braking technology. Its robust construction, precise design, and proven compatibility with a range of Volkswagen models make it an ideal choice for drivers seeking reliable stopping power and long‑term durability. Whether you are restoring a classic Golf or maintaining a modern vehicle, the ABS 7173‑S delivers performance that meets the highest standards of safety and quality.
