Key Technical Specifications

• Model: 7170‑S
• Application: Rear brake drum for a wide range of Volkswagen Transporter models (T1, T2, T3), as well as other light commercial vehicles that use the ABS 7170 series.
• Material Composition: High‑strength cast iron with an engineered heat‑resistant coating to reduce wear and extend service life.
• Dimensions: Outer diameter, inner diameter, thickness, and weight are precisely matched to OEM tolerances, ensuring a perfect fit without modification.
• Heat Dissipation: Optimized internal geometry promotes efficient heat transfer, minimizing brake fade during heavy use.

Performance Highlights

The ABS 7170‑S drum is engineered to provide consistent braking performance under a variety of operating conditions. Its robust construction resists cracking and warping even after repeated exposure to high temperatures, while the smooth interior surface ensures uniform pad contact.

• Consistent Stopping Power: Maintains reliable brake response across temperature ranges from -20°C to +60°C.
• Reduced Wear: The advanced coating reduces friction wear on brake pads, extending their lifespan.
• Low Noise & Vibration: Precision machining and balanced design minimize noise during operation.

Compatibility Overview

The ABS 7170‑S drum is specifically tailored for the following vehicle platforms, but its universal fitment makes it suitable for many other models that share similar rear axle geometry:

• Volkswagen Transporter T1 (1979–1985)
• Volkswagen Transporter T2 (1986–1993)
• Volkswagen Transporter T3 (1994–2000)
• Other light commercial vehicles with the ABS 7170 series rear brake architecture.

Installation Guide

Installing the ABS 7170‑S drum is straightforward for technicians familiar with standard rear brake assembly procedures. The following steps outline a typical installation process:

1. Preparation: Remove the wheel and existing brake components, ensuring the hub and axle are clean.
2. Brake Pad Removal: Detach the brake pads from the caliper or drum assembly. Inspect for wear or damage.
3. Drum Removal: Loosen the retaining bolts that secure the drum to the hub. Carefully lift the drum away, taking care not to damage the brake shoes.
4. Inspection: Check the drum surface for scoring or glazing. Clean with a non‑abrasive brush and isopropyl alcohol if necessary.
5. Installation: Place the new ABS 7170‑S drum onto the hub, aligning it with the retaining bolts. Tighten bolts to the manufacturer’s torque specification.
6. Brake Pad Reassembly: Install fresh brake pads or shoes, ensuring proper alignment and spring tension.
7. Bleed System (if applicable): If the vehicle uses a hydraulic brake system, bleed the brakes to remove air from the lines.
8. Final Checks: Verify that the drum rotates freely without binding. Test the braking function at low speed before full operation.

Maintenance Tips

Regular maintenance extends the life of the ABS 7170‑S drum and ensures optimal safety:

• Periodic Inspection: Check for surface wear, cracks, or glazing every 10,000–15,000 km.
• Brake Pad Replacement: Replace pads when the pad material thickness falls below the manufacturer’s minimum threshold.
• Cleaning: Remove brake dust and debris with a soft brush. Avoid abrasive cleaners that could damage the drum surface.
• Avoid Overheating: In heavy traffic or steep descents, use engine braking to reduce heat buildup in the drums.
