Product Details

The Cardone 53-2737 power brake booster is engineered for direct replacement in select 1992-1995 Mitsubishi Expo and 1992-1994 Mitsubishi Expo LRV models. It uses a dual diaphragm with a 9.22-inch diaphragm diameter and an M8 x 1.25 master cylinder stud thread size. This remanufactured booster is intended for vehicles lacking master cylinders and is supplied as a booster with instruction manual.

This part cross-references Mitsubishi MB699422 for the same application.

What It Helps Address

• Hard brake pedal feel caused by reduced vacuum assist
• Inconsistent braking response during normal driving
• Brake booster leakage or internal diaphragm wear
• Corrosion-related booster housing deterioration
• Fitment issues when replacing an original Mitsubishi Expo brake booster

Installation Notes

Verify the vehicle is equipped for a vacuum power brake booster and does not use a master cylinder with this application. Confirm master cylinder stud thread size, mounting depth, and pedal linkage alignment before installation. Follow the included instruction manual and inspect vacuum hoses, check valves, and related brake components during replacement.
