Designed with precision machining and advanced material selection, this caliper integrates seamlessly into modern brake systems while maintaining stringent safety standards.

Key Features

• Robust Construction: Fabricated from high‑strength alloy steel, the caliper body resists fatigue and corrosion under extreme thermal cycling.
• Optimized Geometry: The piston chamber and slide rail design provide efficient hydraulic flow, reducing drag and ensuring consistent brake response.
• Compatibility: Engineered to fit a wide range of front‑wheel configurations, including vehicles with 28 mm to 57 mm brake disc thicknesses.
• Lightweight Design: Weight reduction contributes to improved vehicle dynamics and reduced unsprung mass.
• Ease of Maintenance: Modular piston arrangement allows for straightforward inspection, cleaning, and replacement without extensive disassembly.

Design & Material Composition

The caliper’s core structure is constructed from a gray cast iron alloy, chosen for its excellent wear resistance and ability to dissipate heat efficiently. The piston assembly utilizes hardened steel, ensuring long‑term performance even under repeated high‑temperature exposure.

Internal components are precision‑machined to tolerances that guarantee minimal play between the piston and slide rail. This meticulous engineering reduces noise, vibration, and harshness (NVH) during operation, providing a smoother driving experience.

Performance Characteristics

• Consistent Stopping Power: The caliper’s hydraulic design delivers uniform pressure distribution across the brake pads, resulting in predictable and reliable braking performance.
• Heat Management: Integrated cooling fins and material selection help maintain optimal operating temperatures, mitigating fade during prolonged use.
• Low Maintenance Footprint: The design allows for quick pad replacement and routine inspection without the need for specialized tools or extensive disassembly.

Installation Guidelines

Installing the ABS 420902 Brake Caliper involves a systematic approach to ensure safety and performance:

1. Preparation: Secure the vehicle on a stable lift or jack stands. Remove the wheel and brake disc to access the caliper mounting area.
2. Removal of Existing Caliper: Detach the caliper bolts, carefully disconnect hydraulic lines, and support the caliper with a jack or strap to prevent strain on the brake hose.
3. Installation of New Caliper: Position the new caliper onto the mounting bracket. Align the piston rod with the brake disc and secure the bolts using a torque wrench set to manufacturer specifications.
4. Hydraulic Re‑pressurization: Bleed the brake system to eliminate air pockets, ensuring optimal hydraulic pressure across all wheels.
5. Final Checks: Verify proper alignment of the caliper and pads. Inspect for any leaks or abnormal vibrations before reattaching the wheel and lowering the vehicle.

Maintenance & Inspection

Regular maintenance extends the lifespan of the ABS 420902 Brake Caliper. Key inspection points include:

• Piston Seals: Inspect for wear or leakage. Replace seals if any signs of deterioration are observed.
• Slide Rails: Ensure smooth operation by checking for debris buildup and applying high‑quality grease where appropriate.
• Bolt Tightness: Periodically torque all mounting bolts to the specified values to prevent loosening under vibration.
• Brake Fluid Condition: Replace fluid according to service intervals, as contaminated or degraded fluid can compromise hydraulic performance.
