ABS 9117 Brakeshoe Set

ABS 9117 Brake Shoe Set

The ABS 9117 Brake Shoe Set is a high‑performance component designed for the rear drum brake system of certain Mercedes-Benz and Henschel chassis models, including the T1 bus, van, platform, and chassis variants. This set delivers reliable stopping power, durability, and ease of installation for both professional mechanics and knowledgeable DIY enthusiasts.

Key Features

• Precision Engineering: Each brake shoe is manufactured to exact tolerances, ensuring consistent contact with the drum surface and optimal braking performance.
• High‑Temperature Resistance: The material composition withstands prolonged heat exposure during heavy braking, reducing wear and maintaining friction characteristics.
• Corrosion Protection: A protective coating resists rust and corrosion even in harsh environmental conditions, extending the life of the brake shoes.
• Compatibility: Specifically engineered for the ABS 9117 model series, guaranteeing a perfect fit on rear drum brakes of compatible Mercedes-Benz and Henschel vehicles.
• Ease of Installation: The set includes all necessary components—shoes, springs, and hardware—to simplify the replacement process.

Technical Specifications

Installation Guide

1. Safety First: Secure the vehicle on a flat surface and use jack stands to support it. Disconnect the battery to prevent accidental electrical discharge.
2. Remove Old Shoes: Detach the drum brake assembly, then carefully remove the existing brake shoes using a suitable pry bar or socket set.
3. Inspect Drum Surface: Clean the drum interior with a non‑abrasive cleaner. Verify that the drum is free of cracks and excessive wear.
4. Install Springs: Place the new springs onto the drum, ensuring they sit flush against the drum wall. Align the spring retaining clips as indicated in the diagram.
5. Fit New Shoes: Slide each brake shoe into its designated slot, aligning the mounting holes with the drum’s internal fasteners. Use a torque wrench to tighten bolts to the manufacturer’s specified value.
6. Reassemble Drum Assembly: Carefully reattach the drum to the wheel hub, ensuring no debris interferes with the brake mechanism.
7. Test Brakes: Before driving, pump the brake pedal several times to seat the shoes against the drum. Verify that the brakes engage smoothly and without noise.

Maintenance Tips

• Regularly inspect brake shoes for wear; replace them before they become too thin.
• Keep the drum surface clean to prevent glazing, which can reduce braking efficiency.
• Check spring tension periodically; a loose spring can lead to uneven shoe contact and premature wear.
• Store spare shoes in a dry environment to avoid moisture‑induced corrosion.

Performance Benefits

The ABS 9117 Brake Shoe Set offers:

• Consistent Stopping Power: Even wear across all four shoes ensures balanced braking performance.
• Reduced Noise and Vibration: High‑quality materials minimize squeal and chatter during operation.
• Longevity: Designed to last through extensive use, reducing the frequency of replacement cycles.

Conclusion

The ABS 9117 Brake Shoe Set is a reliable, high‑quality solution for rear drum brake systems on selected Mercedes-Benz and Henschel vehicles. Its precise engineering, durable construction, and straightforward installation make it an excellent choice for maintaining optimal braking performance and safety.
