ABS 3439 with Brake Drums

ABS 3439 Brake Drum Overview

The ABS 3439 is a high‑performance brake drum designed for rear suspension systems of various European passenger cars, notably the Peugeot, Citroën, and DS models. It incorporates an integrated ABS sensor ring that ensures optimal braking performance under all driving conditions.

Key Technical Features

• Diameter: Ø229 mm – a standard size that matches the original equipment for many compact and mid‑size vehicles.
• Thickness: 51 mm – provides sufficient mass to absorb heat while maintaining structural integrity during repeated braking cycles.
• Material Composition: High‑strength steel alloy with a specialized coating that resists corrosion and wear.
• ABS Sensor Integration: Built‑in sensor ring compatible with the vehicle’s ABS control unit, enabling precise modulation of brake pressure.
• Compatibility: Designed for rear wheels on models such as the Peugeot 207, 208, C3, and DS 3; also suitable for older variants like the Citroën C‑Elysée.

Installation Highlights

Installing the ABS 3439 brake drum is straightforward for technicians familiar with rear drum systems. The process involves:

1. Removing the existing drum and retaining all mounting hardware.
2. Aligning the new drum’s sensor ring with the vehicle’s ABS module.
3. Securing the drum using the original bolts, ensuring torque specifications are met to prevent vibration.
4. Re‑installing the brake shoes and adjusting shoe clearance for optimal braking feel.

Performance Benefits

The combination of a robust steel core and an integrated ABS sensor yields several advantages:

• Consistent Braking: The ABS system can accurately detect wheel lock‑up, maintaining traction during emergency stops.
• Heat Dissipation: The drum’s thickness allows for efficient heat spread, reducing the risk of brake fade on prolonged use.
• Durability: The protective coating resists rust and wear, extending service life even in harsh climates.

Maintenance Tips

To keep the ABS 3439 performing at its best, follow these routine checks:

• Inspect the sensor ring for scratches or debris that could interfere with ABS signal transmission.
• Verify brake shoe wear and replace them when they reach the manufacturer’s minimum thickness.
• Check for any signs of drum warping, especially after high‑temperature events such as long descents.
