ABS 726171 Brake Caliper

ABS 726171 Brake Caliper

The ABS 726171 Brake Caliper is a high‑performance braking component engineered for rear axle applications in a wide range of passenger vehicles, including models from Chevrolet, Daewoo, and related brands. Designed with precision machining and advanced material selection, this caliper delivers reliable stopping power while maintaining durability under demanding driving conditions.

Design & Construction

The caliper features a cast iron body that provides excellent heat dissipation and structural integrity. The housing incorporates a dual‑pivot mounting system, allowing for smooth piston movement and consistent brake pad contact. A sealed hydraulic circuit ensures minimal leakage, while the integrated anti‑wear pads reduce friction wear over extended use.

Key design elements include:

• High‑strength cast iron shell for thermal stability.
• Dual piston arrangement to evenly distribute pressure across the brake pad surface.
Integrated spring return mechanism that guarantees rapid piston retraction after braking events.
• Corrosion‑resistant coating applied to all exposed metal surfaces.

Material Composition

The core material of the ABS 726171 is a gray cast iron alloy, chosen for its superior heat capacity and resistance to thermal shock. The pistons are fabricated from high‑grade steel with a surface finish that reduces friction. All internal components are treated with anti‑corrosion coatings to extend service life in varied climates.

Compatibility & Fitment

This caliper is specifically engineered for the rear left axle of several vehicle models, including:

• Chevrolet Lacetti Estate 1.6/1.8/2.0 D / 1.6 LPG
• Daewoo Gentra/Lacetti/Nubira series
• Other Chevrolet and Daewoo vehicles with similar rear axle configurations.

The ABS 726171 is available in both left‑handed and right‑handed variants, ensuring proper fitment regardless of vehicle orientation. Its mounting brackets are designed to align precisely with OEM bolt patterns, facilitating a straightforward installation process.

Performance Characteristics

When paired with compatible brake pads, the ABS 726171 delivers:

• Consistent stopping force across a wide temperature range.
• Reduced fade during prolonged braking sessions.
• Minimal noise and vibration due to balanced piston operation.

The caliper’s design promotes even pad wear, which translates into longer pad life and reduced maintenance intervals. Its high thermal conductivity helps dissipate heat quickly, maintaining optimal brake performance even under heavy use.

Installation Guide

1. Remove the existing caliper: Loosen the mounting bolts, disconnect the hydraulic line, and carefully lift the caliper from the wheel assembly.
2. Inspect the brake rotor: Ensure it is free of cracks or excessive wear before proceeding.
3. Mount the new ABS 726171: Align the mounting brackets with the vehicle’s bolt pattern, secure with bolts to the specified torque settings.
4. Reconnect hydraulic lines: Attach the brake line to the caliper’s inlet port, ensuring a tight seal.
5. Bleed the braking system: Remove any trapped air to restore full hydraulic pressure.
6. Test drive: Verify that the brakes engage smoothly and that there is no abnormal noise or vibration.

Maintenance Recommendations

To preserve optimal performance, follow these maintenance steps:

• Inspect brake pads every 10,000 miles (or as recommended by the vehicle manufacturer).
• Check for any signs of corrosion on the caliper body and pistons.
• Ensure hydraulic fluid is at the correct level and free from contaminants.
• Replace worn or damaged components promptly to avoid brake failure.

Technical Specifications

Conclusion

The ABS 726171 Brake Caliper exemplifies engineering excellence in rear braking systems. Its robust cast‑iron construction, dual piston design, and precise fitment for a variety of Chevrolet and Daewoo vehicles make it an ideal choice for drivers seeking reliable stopping power and long‑term durability. By adhering to the recommended installation and maintenance procedures, owners can enjoy consistent brake performance throughout the vehicle’s lifespan.
