ABS 630111 Brake Caliper

ABS 630111 Brake Caliper

The ABS 630111 Brake Caliper is a high‑performance braking component designed for rear disc brakes on a wide range of Citroën models, including the C5 I, II, and III Break variants. It is engineered to deliver reliable stopping power while maintaining durability under demanding driving conditions.

Key Design Features

• Aluminum Construction: The caliper body is fabricated from lightweight yet robust aluminum alloy, reducing unsprung mass and improving vehicle handling.
• Dual‑Piston Configuration: Two pistons provide even pressure distribution across the brake pads, enhancing braking efficiency and reducing pad wear.
• Optimized Heat Dissipation: Integrated cooling fins and a vented design allow heat to escape quickly, preventing brake fade during prolonged use.
• Corrosion‑Resistant Finish: A protective coating resists rust and corrosion, extending the life of the caliper in varied climates.
• Precision Machining: Tight tolerances ensure smooth piston movement and consistent brake performance.

Compatibility Overview

The ABS 630111 Brake Caliper is specifically engineered for the following Citroën models:

• Citroën C5 I (DC)
• Citroën C5 II (RC, Re)
• Citroën C5 III Break (TD)

It is available for both left and right rear positions, ensuring symmetrical braking performance across the vehicle.

Installation Guidelines

1. Preparation: Safely lift the vehicle and secure it on jack stands. Remove the rear wheel to access the brake assembly.
2. Remove Existing Caliper: Detach the brake hose, unscrew the caliper mounting bolts, and carefully slide the old caliper away from the rotor.
3. Install New Caliper: Position the ABS 630111 onto the mounting bracket, aligning it with the rotor. Tighten the bolts to the manufacturer’s torque specification.
4. Reattach Brake Hose: Connect the brake hose to the new caliper, ensuring a snug fit without leaks.
5. Reinstall Wheel: Place the wheel back on, lower the vehicle, and torque the lug nuts to spec.
6. Brake Fluid Check: Inspect the brake fluid level and top up if necessary. Bleed the brakes to remove any air pockets.

Maintenance Tips

• Regular Inspection: Check the caliper pistons for smooth operation and look for any signs of leakage or corrosion.
• Pad Replacement: Replace brake pads when the wear indicators reach the recommended thickness to maintain optimal braking performance.
• Fluid Refresh: Change the brake fluid every 2–3 years to prevent moisture buildup and preserve hydraulic integrity.
• Cleaning: Use a brake cleaner to remove dust and debris from the caliper surface, especially after road salt exposure.

Performance Benefits

The ABS 630111 Brake Caliper delivers:

• Consistent Stopping Power: Dual‑piston design ensures even pressure distribution.
• Reduced Fade: Efficient heat dissipation keeps the brakes cool during heavy use.
• Lightweight Advantage: Aluminum construction lowers unsprung mass, improving ride quality.
• Longevity: Corrosion‑resistant finish and precise machining extend service life.
