MPA Electrical B3222 Power Brake Booster

Overview

MPA Electrical B3222 is a remanufactured vacuum power brake booster built for direct brake assist replacement. It is engineered to deliver strong vacuum-assisted braking with reduced pedal effort and is tested at the end of production for consistent performance.

Compatible with 2005-2012 Nissan Pathfinder applications, this booster is a standard replacement unit with a metal housing and a 10.92-inch diaphragm. The B3222 is supplied without a master cylinder, brake pedal rod extension, gasket, seal, or mounting bracket.

Key Features

• Vacuum booster design for brake assist
• Remanufactured standard replacement construction
• Metal housing for durable service
• 10.92-inch diaphragm diameter
• 8 x 1.25 mm master cylinder stud thread size
• End-of-line tested for output consistency

Detailed Description

The MPA Electrical B3222 power brake booster is built for Nissan Pathfinder brake system service where vacuum assist and pedal feel matter. Its remanufactured construction uses specially treated components to support vacuum sealing and pressure transfer, while the 10.92-inch diaphragm and two-stud mounting layout reflect the original application design. This part cross-references Nissan OE numbers 47210EA02A and 47210EA02B for the same application.

MPA Electrical’s reman booster line focuses on replacement units that are tested before release and built to restore braking assist performance without changing the vehicle’s original brake system layout. For Pathfinder owners replacing a worn booster, B3222 provides a direct-fit service part for the listed model years.

What It Helps Address

• Hard brake pedal feel
• Reduced braking assist
• Vacuum seal loss in the booster assembly
• Inconsistent pressure transfer during braking
• Wear-related booster performance decline

Installation Notes

Verify master cylinder compatibility before installation, since the master cylinder is not included. Confirm the 8 x 1.25 mm stud thread size and the two-stud mounting layout against the original part before assembly. Use the vehicle’s existing brake system specifications to confirm proper fitment for the Pathfinder application.

Quality Assurance

MPA Electrical subjects each unit to 100% end-of-line testing using proprietary equipment to verify performance before release. The remanufactured design and tested vacuum booster construction support consistent brake assist output for the listed application.
