ABS 422302 Brake Caliper

ABS 422302 Brake Caliper Overview

The ABS 422302 Brake Caliper is a high‑performance braking component designed for the rear axle of Mercedes-Benz vehicles, particularly the C‑class series. This caliper delivers reliable stopping power while maintaining durability under demanding driving conditions.

Key Features and Design Attributes

• Material Composition: Constructed from a high‑strength aluminum alloy, the caliper offers an optimal balance between weight reduction and structural integrity. The alloy is engineered to withstand high thermal loads during braking.
• Heat Dissipation: Integrated ventilated piston plates enhance heat transfer, reducing brake fade and ensuring consistent performance across repeated stops.
• Compact Geometry: The caliper’s streamlined shape allows for efficient airflow around the rotor, contributing to improved cooling efficiency.
• Compatibility: Designed specifically for the MERCEDES‑BENZ C‑class rear axle, it aligns with OEM specifications for both left and right side mounting.
• Ease of Installation: The caliper features a standardized mounting interface, enabling straightforward replacement without extensive modifications to the brake system.

Performance Characteristics

The ABS 422302 is engineered to provide consistent braking force distribution, minimizing wheel lock‑up during emergency stops. Its robust construction ensures that the caliper can handle high braking temperatures, which is critical for maintaining safety in both everyday driving and spirited performance scenarios.

Thermal Management

The ventilated piston design promotes rapid heat dissipation, preventing excessive temperature buildup that could otherwise lead to brake fade. This feature is especially valuable during prolonged downhill braking or high‑speed deceleration.

Durability and Longevity

Thanks to its high‑strength alloy construction, the ABS 422302 exhibits excellent resistance to corrosion and mechanical wear. The caliper’s design also incorporates precision machining tolerances that reduce friction between moving parts, extending overall component life.

Installation Guidelines

When installing the ABS 422302 Brake Caliper, follow these essential steps:

1. Remove the existing caliper: Carefully detach the brake hose and unscrew the mounting bolts. Keep all hardware for reuse.
2. Clean the mounting surface: Use a solvent to remove any grease or debris from the rotor and caliper bracket.
3. Position the new caliper: Align the mounting holes with the bracket, ensuring that the piston faces are correctly oriented.
4. Screw in place: Tighten the bolts to the manufacturer’s specified torque sequence.
5. Reattach the brake hose: Verify that the hose is seated properly and free of kinks.
6. Bleed the brake system: Remove any trapped air to restore optimal braking pressure.

Maintenance Tips

• Inspect the caliper pistons for signs of wear or damage during routine service intervals.
• Check the brake fluid level and condition; replace if contaminated or degraded.
• Ensure that the rotor surface remains free from scoring or glazing, which can affect caliper performance.

Applications and Vehicle Compatibility

The ABS 422302 is specifically engineered for:

• MERCEDES‑BENZ C‑class rear axle (right side)
• Other Mercedes-Benz models that share the same caliper mounting geometry, provided they meet OEM specifications.

Technical Specifications Summary

Conclusion

The ABS 422302 Brake Caliper exemplifies precision engineering tailored for Mercedes-Benz rear braking systems. Its combination of lightweight construction, advanced heat management, and robust durability makes it a reliable choice for drivers seeking consistent stopping performance without compromising vehicle integrity.
