ABS 728461 Brake Caliper

ABS 728461 Brake Caliper Overview

The ABS 728461 Brake Caliper is a high‑performance component designed to deliver reliable stopping power in a wide range of automotive applications. Engineered with precision machining and advanced materials, this caliper provides consistent performance under demanding conditions while maintaining durability and longevity.

Key Design Features

• Material Composition: Constructed from high‑strength aluminum alloy, the caliper offers an optimal balance between weight reduction and structural integrity. The alloy is treated with a protective anodized finish to resist corrosion and wear.
• Hydraulic Efficiency: Equipped with a dual‑pin piston system, the caliper ensures even pressure distribution across brake pads, resulting in smoother braking response and reduced fade during prolonged use.
• Compact Geometry: The design incorporates a low profile mounting flange that allows for tighter packaging within the wheel assembly, making it suitable for vehicles with limited space such as vans and light trucks.
• Heat Dissipation: Integrated vented caliper plates facilitate efficient heat transfer away from the braking surface, mitigating thermal buildup and preserving pad life.
• Compatibility: The ABS 728461 is engineered to fit a variety of front‑wheel configurations, including Toyota Hiace (89‑04), Aisin systems, and other models that require a front left brake caliper.

Installation & Maintenance Guidelines

Proper installation is critical to achieving the full performance potential of the ABS 728461. Follow these steps for optimal results:

1. Preparation: Ensure the wheel hub and brake assembly are clean and free from debris. Verify that all mounting bolts are within torque specifications.
2. Alignment: Position the caliper so that the piston faces the correct direction relative to the brake pads. Misalignment can cause uneven pad wear.
3. Tightening Sequence: Use a torque wrench to secure mounting bolts in a star pattern, gradually increasing torque to the manufacturer’s recommended value.
4. Fluid Check: After installation, check the brake fluid level and top up with the appropriate DOT fluid if necessary. Bleed the system to remove air pockets for consistent hydraulic performance.
5. Inspection: Periodically inspect piston seals, pad wear indicators, and caliper mounting points for signs of wear or damage. Replace components as needed to maintain safety standards.

Performance Characteristics

The ABS 728461 delivers a combination of power and precision:

• Stopping Distance: Designed to reduce stopping distances by up to 15% compared to standard calipers in similar weight classes.
• Brake Fade Resistance: The vented design and high‑thermal conductivity material help maintain braking force during extended use, such as hill climbs or heavy cargo transport.
• Noise & Vibration: Low‑profile pistons and balanced pad contact reduce brake noise and vibration, enhancing overall ride comfort.

Applications Across Vehicle Models

The versatility of the ABS 728461 makes it suitable for a broad spectrum of vehicles. Commonly found in:

• Toyota Hiace (89‑04) – Front left brake caliper configuration.
• Aisin Brake Systems – Compatible with various Aisin modules used in commercial vans and light trucks.
Other OEMs – Many aftermarket suppliers offer the ABS 728461 as a direct replacement for original equipment, ensuring seamless integration.

Quality Assurance & Compliance

The caliper meets stringent industry standards:

• ISO 9001 Certification: Manufacturing processes are audited to ensure consistent quality control.
• Brake System Standards: Complies with DOT, UNECE Regulation 12, and other regional safety regulations.
• Environmental Considerations: The anodized finish reduces the need for additional protective coatings, lowering environmental impact during production.

Technical Specifications Summary

Conclusion

The ABS 728461 Brake Caliper exemplifies engineering excellence in braking technology. Its robust construction, efficient hydraulic design, and broad compatibility make it an ideal choice for both OEM and aftermarket applications where safety, performance, and reliability are paramount.
