Product Details

This MPA Electrical disc brake caliper is remanufactured at an IATF 16949 facility using a multi-step inspection process. Cores with heavy pitting or severe corrosion are removed from service early, while reusable steel components are cleaned and checked before assembly. Phenolic pistons are replaced with new components during remanufacturing, and threaded areas are cleaned and chased for OE-type fitment and function. For Nissan Frontier, Nissan Pickup, and Nissan D21 front left brake service, BC181673 provides a direct replacement option built around the original caliper design.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Caliper Helps Address

• Uneven or reduced front brake performance
• Brake fluid leakage at the caliper inlet or seals
• Sticking or dragging front left brake operation
• Corrosion-related caliper wear on cast iron housings
• Noise or pedal issues caused by worn caliper components

Installation Notes

Verify the front left position, inlet thread size, and mounting dimensions before installation. Inspect brake hoses, pads, and rotor condition during service, and replace worn friction components as needed. Bleed the brake system after installation and confirm proper caliper movement and pedal feel before returning the vehicle to service.

Quality Assurance

BC181673 is remanufactured with QC checkpoints throughout teardown, cleaning, machining, assembly, and final inspection. Aluminum caliper sealing surfaces are machined for a tight inlet seal when applicable, rubber components are material-tested, and cast iron housings receive corrosion-resistant coating for OE-style protection. Final inspection includes thread verification and go/no-go testing before release.
