Each piston is fitted with a high‑strength steel rod to ensure rapid response and minimal flex during braking.

Key construction highlights include:

• Dual‑pivot mounting for symmetrical load distribution.
• High‑grade cast iron body that resists cracking under high temperatures.
• Precision‑machined piston chambers to reduce friction and improve hydraulic efficiency.
• Integrated cooling fins that enhance heat dissipation during prolonged use.

Performance Characteristics

The ABS 422381 Brake Caliper is engineered for optimal braking performance, featuring:

• Consistent stopping power across a wide temperature range.
• Reduced pad wear due to balanced piston action.
• Improved heat management, minimizing brake fade during heavy duty operation.
• Low vibration signature for a smoother driving experience.

Installation Guide

Installing the ABS 422381 Brake Caliper is straightforward, provided that the vehicle’s brake system is compatible. Follow these steps to ensure proper fitment:

1. Remove the existing caliper. Use a jack and appropriate tools to lift the vehicle and disconnect the brake lines.
2. Inspect mounting points. Verify that the caliper brackets are free of corrosion or damage.
3. Align the new caliper. Position the ABS 422381 so that the piston aligns with the brake pad and rotor.
4. Screw in mounting bolts. Tighten to the manufacturer’s specified torque settings.
5. Reconnect brake lines. Ensure all seals are intact and free of leaks.
6. Purge the braking system. Remove air pockets by bleeding the brakes according to standard procedures.

Maintenance Tips

To keep the ABS 422381 Brake Caliper operating at peak performance, adhere to these maintenance practices:

• Regular inspections. Check for signs of wear or damage on pistons and seals every 10,000 miles.
• Clean the caliper housing. Remove brake dust with a soft brush and mild solvent to prevent corrosion.
• Replace pads as needed. Ensure pad thickness remains above the minimum specification for safe operation.
• Monitor hydraulic fluid. Replace brake fluid according to the vehicle’s service schedule to maintain proper pressure.

Compatibility & Applications

The ABS 422381 Brake Caliper is designed for a broad spectrum of vehicles, including but not limited to:

• MERCEDES‑BENZ models such as the Sprinter 3‑T Van, Vito Van, and various bus configurations.
• VW commercial and passenger vehicles, especially those with LT 28‑35 or LT 28‑46 chassis.
• Chrysler, Fiat, and Lancia models that require a robust front brake caliper solution.
• Other OEMs that specify the ABS 422381 part number for their braking systems.
