ABS 623721 Brake Caliper

ABS 623721 Brake Caliper

The ABS 623721 Brake Caliper is a high‑performance component designed for the rear braking system of selected Peugeot and Citroën models, including the 206, 306, Xsara, and ZX series. Engineered with precision machining and advanced materials, this caliper delivers reliable stopping power while maintaining durability under demanding driving conditions.

Key Features

• Aluminum Construction: The caliper housing is fabricated from lightweight yet robust aluminum alloy, reducing unsprung mass and improving overall vehicle dynamics.
• Dual‑Piston Design: Equipped with two pistons that provide even pressure distribution across the brake pads, enhancing braking efficiency and minimizing pad wear.
• High‑Temperature Resistance: The internal components are engineered to withstand elevated temperatures during heavy braking, ensuring consistent performance over time.
• Corrosion‑Resistant Finish: A protective coating resists rust and corrosion, extending the service life of the caliper in various environmental conditions.

Compatibility Overview

The ABS 623721 Brake Caliper is specifically tailored for rear axle applications on a range of models. Its dimensions and mounting points match those found on:

• Peugeot 206 (3/5‑door)
• Peugeot 306 (3/5‑door, Cabriolet)
• Citroën Xsara (5‑door)
• Citroën ZX (3/5‑door)
• X‑series and other related models that share the same rear suspension architecture.

Installation Guidelines

1. Preparation: Ensure the vehicle is securely lifted and supported. Remove the wheel, brake disc, and existing caliper assembly.
2. Removal of Old Caliper: Carefully detach the hydraulic lines and mounting bolts. Use a torque wrench to avoid over‑tightening.
3. Installation of New Caliper: Position the ABS 623721 onto the mounting bracket, aligning all pins and slots accurately.
4. Reconnection: Reattach hydraulic lines, ensuring no leaks. Tighten bolts to the manufacturer’s specified torque settings.
5. Bleeding the System: Bleed the brake system to eliminate air pockets, following standard procedures for rear brakes.
6. Final Check: Verify that the caliper moves freely and that the brake pads are seated correctly against the disc.

Maintenance Tips

• Regular Inspection: Periodically check for signs of wear, corrosion, or hydraulic fluid leaks. Inspect pistons for smooth operation.
• Brake Fluid Replacement: Replace brake fluid according to the vehicle’s service schedule to maintain optimal hydraulic pressure.
• Pad Replacement: When pads reach the minimum thickness threshold, replace them with compatible high‑performance pads to preserve braking efficiency.
• Cleaning: Use a non‑abrasive cleaner to remove brake dust from the caliper housing. Avoid contact with hydraulic components.

Performance Benefits

The ABS 623721 Brake Caliper offers several advantages that enhance driving safety and comfort:

• Consistent Braking Response: Dual‑piston action ensures uniform pressure, reducing the likelihood of uneven pad wear.
• Reduced Unsprung Mass: Lightweight aluminum construction improves suspension response and ride quality.
• Heat Dissipation: Designed to manage high thermal loads, preventing brake fade during prolonged or aggressive braking.
• Longevity: Corrosion‑resistant finish and durable materials contribute to a longer service life compared to standard calipers.

Technical Specifications

Conclusion

The ABS 623721 Brake Caliper stands out as a reliable, high‑quality component for rear braking systems on selected Peugeot and Citroën vehicles. Its thoughtful design—combining lightweight aluminum construction, dual‑piston mechanics, and heat‑resistant materials—ensures that drivers experience consistent stopping power, enhanced safety, and long-term durability.
