• Optimized Geometry: Designed to accommodate a brake disc thickness of 21.9 mm and a diameter of 54 mm.
• Ease of Maintenance: Features removable pistons and a straightforward service procedure for routine inspections.

Design & Material Specifications

The caliper’s body is fabricated from an aluminum alloy that balances lightweight characteristics with structural integrity. The gray cast finish not only provides aesthetic appeal but also enhances thermal conductivity, allowing heat to spread evenly across the braking surface during high‑intensity use.

Dimensional Details

• Disc Thickness: 21.9 mm – ensures optimal contact with brake pads.
• Disc Diameter: 54 mm – suitable for mid‑size automotive applications.
• Mounting Orientation: Front axle, right side configuration to match standard vehicle layouts.

Installation Guidelines

Installing the ABS 726482 Brake Caliper involves a series of steps that prioritize safety and precision. Below is a concise guide for technicians:

1. Preparation: Secure the vehicle on jack stands and remove the wheel to access the brake assembly.
2. Remove Existing Caliper: Detach the caliper bolts, carefully disconnect hydraulic lines, and set aside the old component.
3. Position New Caliper: Align the mounting flanges with the hub, ensuring that the pistons are correctly seated.
4. Bolt in Place: Tighten bolts to the manufacturer’s torque specifications, typically around 80 Nm for aluminum components.
5. Hydraulic Re‑pressurization: Bleed the brake system to eliminate air pockets and restore full hydraulic pressure.
6. Final Checks: Verify that the caliper moves freely and that there is no leakage from the hydraulic lines.

Troubleshooting Common Issues

While the ABS 726482 Brake Caliper is engineered for reliability, certain scenarios may arise during operation or maintenance:

• Piston Seizure: If the caliper fails to retract, inspect pistons for corrosion and clean with a suitable solvent.
• Brake Fluid Leaks: Check all seals and fittings; replace any damaged components promptly.
• Uneven Pad Wear: Ensure that pads are correctly positioned and that the caliper is properly centered over the rotor.

Performance Benefits

The design of the ABS 726482 Brake Caliper offers several performance advantages for drivers and mechanics alike:

• Consistent Stopping Power: The caliper’s geometry ensures even pressure distribution across brake pads.
• Heat Management: Aluminum alloy construction dissipates heat efficiently, reducing the risk of fade during prolonged braking.
• Longevity: High‑quality materials and precise machining extend component life under typical driving conditions.

Maintenance & Service Recommendations

Regular maintenance is key to preserving the integrity of the brake system. Follow these guidelines for optimal performance:

1. Periodic Inspection: Check caliper pistons, seals, and mounting bolts every 10,000 km.
2. Brake Fluid Replacement: Replace fluid at least once a year to maintain hydraulic efficiency.
3. Pad Replacement: Monitor pad thickness; replace when wear reaches the minimum safe level (typically around 3 mm).

Compatibility Summary

The ABS 726482 Brake Caliper is specifically tailored for vehicles that utilize the following part numbers and configurations:

• A0004205683 – Front axle, right side.
• A0014201983 – Front axle, right side.
• 0004205683 – Front axle, right side.
