Technical Specifications

Installation Guide

1. Preparation: Remove the existing brake assembly and clean all mounting surfaces to eliminate debris.
2. Mounting: Align the caliper’s mounting holes with the bracket on the wheel hub. Secure using the supplied bolts, tightening to the manufacturer’s torque specifications.
3. Brake Pad Installation: Insert new brake pads into the caliper housing, ensuring proper seating and alignment.
4. Hydraulic Check: Re‑pressurize the braking system according to vehicle service procedures to eliminate air pockets.
5. Test Drive: Conduct a low‑speed test drive to confirm correct operation before resuming normal driving conditions.

Performance Benefits

• Enhanced Stopping Power: The cast iron construction provides superior heat dissipation, reducing brake fade during heavy use.
• Longevity: Designed to withstand repeated thermal cycling without significant wear or distortion.
• Consistent Response: Dual‑pivot design ensures even pressure distribution across the brake pads, leading to predictable braking performance.
• Reduced Maintenance: The robust build reduces the frequency of pad replacement compared to lighter caliper alternatives.

Applications and Use Cases

The ABS 420191 Brake Caliper is ideal for:

• Commercial vans and minibuses that require reliable braking under load.
• Passenger vehicles operating in urban or highway environments where consistent stopping performance is critical.
• Aftermarket upgrades aimed at improving safety without compromising vehicle compatibility.

Maintenance Tips

• Inspect brake pads for wear every 10,000 km and replace when the pad thickness falls below manufacturer recommendations.
• Check caliper bolts for tightness at regular service intervals to prevent loosening due to vibration.
• Clean the caliper surface with a non‑abrasive cleaner to remove brake dust buildup, which can affect heat transfer.

Conclusion

The ABS 420191 Brake Caliper combines proven engineering with practical design to deliver dependable braking performance across a spectrum of vehicle models. Its cast iron construction, dual‑pivot architecture, and straightforward installation make it a preferred choice for both OEM replacements and aftermarket enhancements.
