Detailed Description

MPA Electrical B1131 is engineered to restore vacuum-assisted braking performance on compatible Ford Taurus and Ford Sable models, along with Mercury Sable, Lincoln Continental, and Lincoln Mark VII applications. The remanufactured design uses specially treated replacement components to help maintain vacuum integrity and dependable pressure transfer, which supports smoother brake assist under normal driving and stop-and-go conditions. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Hard brake pedal feel caused by a weak booster
• Reduced brake assist during normal braking
• Vacuum seal loss in an aging booster assembly
• Inconsistent pedal response in stop-and-go driving
• Brake performance issues tied to booster wear on Ford Taurus, Ford Sable, and related applications

Installation Notes and Tips

Verify master cylinder stud thread size, mounting stud layout, and diaphragm diameter before installation. Because the master cylinder is not included, transfer or replace related brake components as needed during service. Confirm vehicle-specific fitment for 1990-1995 Ford Taurus, 1994-1995 Ford Sable, 1990-1995 Mercury Sable, 1990-1994 Lincoln Continental, and 1990 Lincoln Mark VII before ordering.

Quality Assurance

MPA Electrical tests each booster at the end of production using proprietary equipment to verify performance before release. The remanufacturing process is focused on restoring vacuum seal quality and pressure transfer for dependable brake assist.
