ABS 422091 Brake Caliper

ABS 422091 Brake Caliper

The ABS 422091 Brake Caliper is a high‑performance component designed for the front braking system of Fiat Punto and Lancia Y models, including various engine configurations such as the 1.2 L 16V 80, 188 cc, and other related variants. It is engineered to provide reliable stopping power while maintaining durability under demanding driving conditions.

Key Features

• Material Composition: Made from gray cast iron (Fonte grise), which offers excellent thermal conductivity and resistance to wear, ensuring consistent braking performance even during prolonged use.
• Compatibility: Specifically tailored for the Fiat Punto and Lancia Y series. The caliper fits models with 12 mm brake disc thickness and 48 mm diameter, matching the OEM specifications for these vehicles.
• Design: Features a robust mounting structure that secures the caliper to the front axle (Vorderachse links), providing stability and reducing flex during braking. The design also accommodates standard ATE brake system components.
• Performance: Delivers consistent hydraulic pressure across all operating temperatures, thanks to its precise machining tolerances and high‑quality piston seals.

Installation Overview

Installing the ABS 422091 Brake Caliper involves removing the existing caliper assembly, aligning the new unit with the mounting bolts, and ensuring proper clearance for the brake pads. The caliper’s design allows for straightforward bolt placement and secure fastening, minimizing installation time while guaranteeing safety.

Maintenance Tips

• Regular Inspection: Check for signs of wear or corrosion on the cast‑iron body and piston seals every 10,000 km or during routine service intervals.
• Piston Seal Replacement: Replace seals if you notice any leakage or reduced braking efficiency. This helps maintain optimal hydraulic pressure.
• Brake Pad Compatibility: Use OEM or high‑quality aftermarket pads that match the caliper’s dimensions to avoid uneven wear and ensure balanced braking.

Performance Benefits

• Enhanced Stopping Power: The cast‑iron construction provides a stable platform for brake pad contact, translating into stronger and more reliable stopping capability.
• Heat Dissipation: Excellent thermal properties help prevent brake fade during aggressive driving or extended braking sessions.
• Longevity: Designed to withstand the rigors of daily use, the caliper’s robust build reduces the need for frequent replacements.

Technical Specifications

Conclusion

The ABS 422091 Brake Caliper stands out as a reliable, high‑quality component for Fiat Punto and Lancia Y vehicles. Its cast‑iron construction, precise engineering, and dedicated compatibility ensure that drivers receive consistent braking performance, safety, and durability across a wide range of driving scenarios.
