ABS 420122 Brake Caliper

ABS 420122 Brake Caliper

The ABS 420122 Brake Caliper is a high‑performance component designed for the rear right braking system of Volvo models such as the C70, S70, V70, and 800 series. It serves as an essential part of the vehicle’s safety architecture, ensuring reliable stopping power under a variety of driving conditions.

Key Functional Characteristics

• Caliper Type: Single‑pin sliding caliper with dual pistons for balanced braking force distribution.
• Material Composition: High‑strength cast iron housing combined with a lightweight aluminum piston assembly to reduce unsprung mass.
• Brake Pad Compatibility: Designed to accommodate standard ABS brake pads used on the specified Volvo models, providing optimal friction and heat dissipation.
• Hydraulic Design: Features a sealed hydraulic chamber that prevents contamination and ensures consistent pressure delivery from the master cylinder.

Performance Benefits

The ABS 420122 caliper delivers superior stopping performance by maintaining uniform pressure across both pistons. This design minimizes brake fade during prolonged use, such as in mountainous terrain or emergency braking scenarios. The lightweight piston construction also contributes to quicker pedal response and reduced driver fatigue.

Installation Overview

Installing the ABS 420122 caliper involves removing the existing rear right caliper assembly and replacing it with the new unit. Key steps include:

1. Secure the vehicle on a lift or jack stands.
2. Drain brake fluid from the system to prevent contamination during removal.
3. Disconnect the caliper mounting bolts and remove the old caliper.
4. Position the new ABS 420122 caliper, ensuring proper alignment with the rotor.
5. Tighten mounting bolts to manufacturer specifications.
6. Re‑attach brake lines and refill the system with fresh brake fluid.
7. Bleed the brakes to eliminate air pockets, ensuring optimal hydraulic performance.

Compatibility Matrix

Maintenance Tips

• Inspect the caliper pistons for wear every 20,000 miles or as recommended by the vehicle manufacturer.
• Check for oil leakage around the piston seals; any seepage can compromise braking performance.
• Replace brake pads when pad thickness falls below 3 mm to maintain optimal contact with the rotor.

Quality Assurance

The ABS 420122 caliper is manufactured under strict quality control protocols, ensuring that each unit meets or exceeds OEM specifications. The component undergoes rigorous testing for:

• Dimensional accuracy to guarantee a perfect fit on the mounting bracket.
• Hydraulic integrity to prevent fluid leaks and maintain consistent pressure.
• Thermal resistance to withstand high temperatures generated during heavy braking.
