Product Details

MPA Electrical B3229 is engineered to deliver vacuum-assisted braking with reduced pedal effort. The remanufactured design uses new replacement and specially treated components to help maintain vacuum sealing and pressure transfer, while end-of-line testing is performed on every unit to verify function before release. This part cross-references Mitsubishi OEM numbers MB895128 and MR449656 for the same application. For Mitsubishi Montero Sport brake repair, B3229 provides a direct replacement option for the vacuum booster assembly without the master cylinder.

Common Problems It Can Help Address

• Hard brake pedal feel
• Reduced brake assist during normal driving
• Vacuum loss at the booster assembly
• Inconsistent pedal response after booster wear
• Brake performance issues related to a failing power brake booster

Installation Notes and Tips

Verify master cylinder compatibility before installation, since the master cylinder is not included. Confirm the 8 x 1.25 mm stud thread size, the 2-stud mounting pattern, and the diaphragm diameter against the original unit on your Mitsubishi Montero Sport. Inspect vacuum hoses, check valves, and pedal linkage condition during replacement to avoid repeat brake assist concerns.
