ABS 520142 Brake Caliper

ABS 520142 Brake Caliper

The ABS 520142 Brake Caliper is a high‑performance component designed for the front right wheel of Citroën and Peugeot models, particularly the ZX/405 series produced between 1992 and 1997. This caliper delivers reliable stopping power while maintaining durability under demanding driving conditions.

Key Features

• Material: Gray cast iron (Fonte grise) construction ensures excellent heat dissipation and resistance to wear.
• Compatibility: Fits the front right brake system of Citroën ZX, Peugeot 405, and related models. It is also compatible with part numbers 440168, 440195, and 95666893.
• Brake Pad Clearance: Designed for a 20.5 mm brake disc thickness, providing optimal pad contact.
• Dimensions: The caliper’s internal geometry matches the original equipment specifications, ensuring seamless integration with existing brake assemblies.
• Design: Features a robust piston assembly that delivers consistent pressure across all operating temperatures.

Installation Overview

Installing the ABS 520142 Brake Caliper involves removing the existing caliper, aligning the new unit with the mounting bolts, and securing it with the supplied hardware. The piston must be re‑centered using a hydraulic press or a dedicated caliper tool to ensure proper pad alignment.

Performance Benefits

• Enhanced Stopping Power: The cast‑iron construction provides superior thermal capacity, reducing brake fade during prolonged use.
• Longer Component Life: Durable materials and precise machining extend the lifespan of both the caliper and associated pads.
• Consistent Brake Feel: Uniform piston movement delivers a predictable pedal response, improving driver confidence.

Maintenance Tips

1. Regularly inspect the piston seals for wear or damage. Replace them if any leakage is detected.
2. Check the brake fluid level and top up with the manufacturer’s recommended DOT fluid to maintain hydraulic integrity.
3. Clean the caliper housing periodically to prevent corrosion, especially in climates with high humidity or road salt exposure.

Compatibility Summary

The ABS 520142 Brake Caliper is specifically engineered for:

• CITROËN ZX (front right)
• PEUGEOT 405 (front right)
• Other models sharing the same front brake architecture, such as the 405 II Berline and 405 II Break.

It is interchangeable with the following part numbers:

• 440168
• 440195
• 95666893

Technical Specifications

Conclusion

The ABS 520142 Brake Caliper is a reliable and proven component for the front right braking system of Citroën and Peugeot vehicles from the early to mid‑1990s.
