ABS 420932 Brake Caliper

ABS 420932 Brake Caliper

The ABS 420932 Brake Caliper is a high‑performance braking component engineered for modern passenger vehicles. Designed with precision machining and advanced materials, it delivers reliable stopping power while maintaining durability under demanding driving conditions.

Key Design Features

• Material Composition: Constructed from high‑strength aluminum alloy, the caliper offers an optimal balance between lightweight construction and structural integrity. The alloy’s excellent thermal conductivity helps dissipate heat during braking, reducing the risk of brake fade.
• Dual‑Piston Configuration: Equipped with a dual‑piston hydraulic system, the caliper ensures even pressure distribution across the brake pads. This design enhances braking efficiency and provides consistent pedal feel.
• Integrated ABS Sensor Mounting: The caliper features a dedicated mounting point for the vehicle’s Anti‑Lock Braking System (ABS) sensor. This integration simplifies installation and guarantees accurate wheel speed monitoring during emergency stops.
• Optimized Pad Clearance: A carefully engineered pad clearance allows for smooth pad movement while minimizing friction. The result is reduced wear on brake pads and improved overall braking performance.
• Corrosion‑Resistant Finish: The caliper’s surface undergoes a protective coating process, providing resistance against rust and corrosion even in harsh environmental conditions.

Compatibility Overview

The ABS 420932 is specifically tailored for use with a range of front-wheel drive vehicles. It is compatible with the following models:

• Peugeot: 207, 307, 308 (all variants)
• Citroën: C4, C4 Coupe (all variants)

These vehicles typically employ the 4400R1 and 4400T3 brake system specifications. The caliper’s dimensions and mounting points are engineered to match these standards precisely.

Installation Guidelines

1. Preparation: Ensure the vehicle is securely lifted on a jack stand. Remove the wheel and inspect the existing caliper for wear or damage.
2. Removal of Old Caliper: Disconnect the brake lines, carefully release any retaining bolts, and slide out the old caliper. Keep all hardware in order to avoid confusion during reassembly.
3. Mounting the ABS 420932: Position the new caliper onto the mounting bracket, aligning it with the pre‑drilled holes. Tighten the mounting bolts to the manufacturer’s torque specifications.
4. Brake Line Reconnection: Reattach the brake lines, ensuring no leaks. Use a brake fluid reservoir and fill with fresh, compatible brake fluid.
5. Pad Installation: Install new brake pads that match the caliper’s pad clearance specifications. Verify proper alignment before proceeding.
6. Bleeding the System: Bleed the brakes to remove any trapped air and restore optimal hydraulic pressure.
7. Final Checks: Inspect all connections, verify brake pedal feel, and perform a short test drive at low speed to confirm proper operation.

Maintenance Tips

• Regularly inspect the caliper for signs of wear or corrosion. Replace any damaged components immediately.
• Check brake fluid levels every 10,000 km and replace the fluid according to the vehicle manufacturer’s schedule.
• Ensure that the ABS sensor remains clean and free from debris to maintain accurate wheel speed readings.
• When replacing brake pads, use a pad material compatible with the caliper’s design to avoid premature wear.

Performance Highlights

The ABS 420932 Brake Caliper is engineered to deliver:

• Consistent stopping power even under high‑temperature conditions, thanks to its superior heat dissipation properties.
• A smooth and predictable pedal feel, enhancing driver confidence during both everyday driving and emergency braking scenarios.
• Reduced pad wear due to the optimized pad clearance and balanced piston pressure distribution.
• Longer component life, attributed to the corrosion‑resistant finish and robust material selection.
