ABS 2655-S Brake Drum

ABS 2655‑S Brake Drum

The ABS 2655‑S Brake Drum is a high‑performance component engineered to deliver reliable stopping power for rear-wheel drive vehicles, particularly those in the Citroën and Peugeot Xsara family. Designed with precision machining and advanced materials, this drum provides consistent braking performance even under demanding driving conditions.

Key Design Features

• Optimized Geometry: The drum features a carefully calculated inner diameter of 203 mm and an outer diameter that accommodates standard brake shoes, ensuring a snug fit within the existing caliper assembly.
• Heat‑Resistant Construction: Made from high‑strength steel alloy with a proprietary heat‑treatment process, the drum resists warping and maintains dimensional stability during prolonged braking sessions.
• Integrated Ventilation Slots: Subtle venting channels are incorporated into the rim to facilitate efficient heat dissipation, reducing brake fade and extending component life.
• Corrosion Protection: A durable anti‑rust coating protects against environmental exposure, ensuring longevity in varied climates.

Material Composition

The core of the ABS 2655‑S Brake Drum is fabricated from a high‑grade steel alloy that balances tensile strength with thermal conductivity. The alloy composition typically includes:

• Carbon (C) – 0.15 % to enhance hardness.
• Manganese (Mn) – 1.5 % for improved toughness.
• Silicon (Si) – 0.4 % to aid in heat dissipation.
• Chromium (Cr) – 0.8 % for corrosion resistance.

Following extrusion, the drum undergoes a controlled annealing cycle that stabilizes its microstructure and reduces internal stresses.

Compatibility Overview

The ABS 2655‑S Brake Drum is specifically engineered for rear axle applications in:

• CITROËN Xsara (all body styles – sedan, hatchback, cabriolet)
• PEUGEOT 306 (3/5‑door variants and Cabriolet models)

Its dimensions align with the original equipment specifications for these vehicles, ensuring a seamless fit without requiring modifications to the brake housing or caliper.

Installation Procedure

1. Safety First: Secure the vehicle on jack stands and remove the rear wheels.
2. Brake Assembly Removal: Detach the brake shoes, caliper bracket, and any retaining hardware. Carefully note the orientation of each component for reassembly.
3. Drum Extraction: Use a drum puller or a suitable pry bar to disengage the old drum from the hub. Inspect the hub surface for damage; clean thoroughly.
4. Mounting the New Drum: Place the ABS 2655‑S Brake Drum onto the hub, aligning it with the mounting flange. Secure using the original bolts or torque specifications provided by the vehicle manufacturer.
5. Reinstall Brake Shoes and Caliper: Position the brake shoes around the new drum, ensuring proper alignment of the shoe springs. Reattach the caliper bracket and secure all fasteners.
6. Brake Fluid Check: Verify that the brake fluid reservoir is at the correct level and that there are no leaks in the system.
7. Wheel Reassembly: Mount the wheels, torque the lug nuts to spec, lower the vehicle, and perform a final wheel torque check.

Maintenance Tips

• Inspect brake shoes for wear every 10,000 km or during routine service intervals.
• Clean the drum surface with a non‑abrasive brush and brake cleaner to remove dust and debris.
• Avoid using metal shavings or abrasive materials that could damage the drum’s finish.
• Check for any signs of vibration or noise during braking; these may indicate misalignment or worn shoes.

Performance Benefits

The ABS 2655‑S Brake Drum offers several advantages over standard aftermarket options:

• Consistent Stopping Power: The drum’s heat‑tolerant design maintains performance even during repeated hard braking.
• Reduced Fade: Ventilation and material choice mitigate temperature rise, preserving brake responsiveness.
• Longevity: Corrosion protection and robust construction extend the service life of both the drum and associated shoes.

Frequently Asked Questions

Can the ABS 2655‑S be used on front brakes?

No. The drum is specifically designed for rear axle applications and does not meet the dimensional or performance requirements of front brake systems.

Is a new set of brake shoes required with this drum?

While existing shoes may fit, it is recommended to inspect them for wear and replace if necessary to ensure optimal braking performance.

Will the drum affect vehicle handling?

The drum’s design maintains the original weight distribution and brake torque characteristics of the vehicle, preserving handling dynamics.

Conclusion

The ABS 2655‑S Brake Drum exemplifies engineering excellence tailored for the Citroën Xsara and Peugeot 306 rear braking systems. Its precise geometry, heat‑resistant material composition, and corrosion protection combine to deliver reliable stopping power, durability, and ease of installation. Whether you’re restoring a classic vehicle or upgrading an existing setup, this drum provides the performance and peace of mind that discerning drivers expect.
