ABS 421171 Brake Caliper

ABS 421171 Brake Caliper Overview

The ABS 421171 Brake Caliper is a high‑performance component designed for the rear braking system of Volkswagen Transporter models, including the 5 Bus, Multivan 5, and other VAG vehicles. This caliper delivers reliable stopping power while maintaining durability under demanding driving conditions.

Key Design Features

• Material Composition: Constructed from a gray cast iron alloy that offers excellent heat dissipation and resistance to wear.
• Pinza (Brake Lever) Configuration: The caliper incorporates a robust pinza de freno mechanism, ensuring consistent hydraulic pressure transfer to the brake pads.
• Compatibility: Engineered specifically for the rear axle of Volkswagen Transporter series, with precise fitment for models such as 7H8615423 and other VAG platforms.
• Weight Efficiency: Designed to reduce unsprung mass, contributing to improved ride quality and handling dynamics.

Performance Characteristics

The ABS 421171 caliper is engineered to provide consistent braking performance across a wide range of temperatures. Its cast iron construction allows for rapid heat dissipation, minimizing brake fade during prolonged use. The integrated pinza ensures that hydraulic pressure is evenly distributed to the brake pads, resulting in uniform wear and extended component life.

Installation & Maintenance

Installing the ABS 421171 involves aligning the caliper with the rear wheel hub and securing it using manufacturer‑specified fasteners. Proper torque settings are critical for maintaining seal integrity and preventing brake fluid leakage. Routine maintenance includes inspecting the hydraulic lines, checking pad wear indicators, and ensuring that the caliper piston moves freely without binding.
