ABS 8803 Brakeshoe Set

Overview

The ABS 8803 Brakeshoe Set is a high‑performance replacement kit designed specifically for the rear drum brakes of certain BMW models from the early 1980s through the mid‑1990s. This set includes all necessary components to restore optimal braking efficiency, ensuring safety and reliability on both daily commutes and spirited driving.

Compatibility

The kit is engineered for a range of BMW rear suspension configurations:

• BMW 5 Series (E28/E34) – models equipped with M10B18, M43B18, or M40B18 engines.
• BMW 5 Sedan (E34) – rear drum brake systems that use the standard ABS 8803 geometry.
• All variants of the 5 Series (1981‑1995) that feature the original ABS 8803 Bremsbackensatz.

Each component is stamped with the unique part numbers: 34211120867, 34211154921, 34211154924, 34211154925, 34211154926, ensuring precise fitment.

Key Features

• Precision‑Machined Shoes – Crafted from high‑grade friction material that delivers consistent stopping power across a wide temperature range.
• Integrated ABS Compatibility – Designed to work seamlessly with the vehicle’s anti‑lock braking system, maintaining electronic control during heavy braking.
• Durable Pad Material – Combines wear resistance with low dust generation for cleaner brake components and reduced maintenance.
• Full Kit Inclusion – Each set contains both left and right shoes, retaining rings, and all necessary hardware for a complete replacement.
• OEM‑Grade Quality – Meets or exceeds original equipment specifications, guaranteeing performance parity with the factory system.

Installation Guide

Replacing the rear drum brakes with the ABS 8803 Brakeshoe Set is a straightforward process that can be completed in under an hour by a competent mechanic:

1. Secure the Vehicle – Raise and support the car on jack stands, then remove the rear wheels.
2. Access the Drum – Detach the brake drum from the wheel hub, taking care not to damage the backing plate.
3. Remove Old Shoes – Slide out the existing shoes, noting their orientation for correct reassembly.
4. Install New Shoes – Place the new shoes into the drum, aligning them with the retaining rings and ensuring proper contact with the brake cylinder.
5. Reassemble – Reinstall the drum, wheel, and any ancillary components such as the parking brake lever or cable.
6. Bleed the System – If necessary, bleed the hydraulic system to eliminate air pockets and restore full braking force.

Performance Benefits

The ABS 8803 Brakeshoe Set delivers several tangible advantages over worn or aftermarket alternatives:

• Enhanced Stopping Power – The friction material is engineered to maintain high coefficient of friction, reducing stopping distances.
• Consistent ABS Response – Properly fitted shoes ensure that the anti‑lock system can modulate pressure accurately during emergency stops.
• Reduced Wear on Rotors and Drums – Even wear patterns prevent uneven drum deformation, extending component life.
• Improved Ride Comfort – Smooth braking action reduces vibration transmitted to the chassis.

Maintenance Tips

To keep the ABS 8803 Brakeshoe Set performing at its best, follow these routine checks:

• Inspect for Wear – Every 10,000 miles or annually, examine shoe thickness and look for glazing or uneven wear.
• Check Brake Fluid – Replace brake fluid every two years to prevent contamination that can affect ABS operation.
• Monitor Dust Levels – Excessive dust may indicate improper installation; clean the drum interior if necessary.
• Verify ABS Indicator – Ensure the vehicle’s dashboard ABS light remains off during normal driving conditions.

Conclusion

The ABS 8803 Brakeshoe Set is a reliable, OEM‑grade solution for BMW rear drum brake replacement. Its precise engineering, compatibility with a wide range of models, and proven performance make it an essential component for maintaining vehicle safety and driving confidence.
