ABS 421571 Brake Caliper

ABS 421571 Brake Caliper

The ABS 421571 Brake Caliper is a high‑performance, OEM‑grade component designed for the front left axle of a wide range of Volkswagen Group vehicles, including Audi, Seat, Skoda, and VW models such as the A4, A6, C4, S4, B5, B6, B7, and EXEO. This caliper is engineered to deliver consistent braking power, durability, and reliability under demanding driving conditions.

Key Features

• Material Composition: The caliper housing is fabricated from a lightweight yet robust aluminum alloy that offers excellent thermal conductivity while maintaining structural integrity. This composition helps dissipate heat quickly during heavy braking, reducing the risk of brake fade.
• Dual‑Piston Design: Equipped with two pistons per side, the caliper provides balanced pressure distribution across the brake pad surfaces, ensuring even wear and optimal stopping performance.
• High‑Temperature Resistance: The internal components are engineered to withstand temperatures exceeding 400 °C, making it suitable for spirited driving, track use, and high‑load applications.
• Precision Machining: All mating surfaces are machined to tight tolerances, guaranteeing a perfect fit with the brake rotor and pad assembly. This precision reduces vibration and enhances overall braking feel.
• Corrosion Protection: The caliper features an anti‑corrosion coating that protects against rust and environmental degradation, extending its service life even in harsh climates.

Compatibility Overview

The ABS 421571 Brake Caliper is compatible with a broad spectrum of front left brake systems across the Volkswagen Group. Below are some of the most common vehicle models and configurations:

• Audi A4 B5/B6/B7 (Sedan, Convertible, Quattro)
• Seat Exeo, A4, A6
• Skoda Superb, Octavia, Kodiaq
• Volkswagen Passat, Golf, Jetta, Tiguan
• All front left brake assemblies that use the OEM part numbers: 8E0615123A, 8E0615123AX, 4B0615123, 8D0615123B, and related variants.

Installation Highlights

Installing the ABS 421571 Brake Caliper follows standard front brake replacement procedures. Key steps include:

1. Safety First: Secure the vehicle on jack stands and remove the wheel.
2. Brake Line Inspection: Check for any leaks or damage before removal.
3. Caliper Removal: Unbolt the caliper from the mounting bracket, carefully disconnect the brake lines, and support the caliper with a jack to avoid strain on the hoses.
