Remanufactured Vacuum Brake Booster

MPA Electrical B1152 is a remanufactured vacuum power brake booster for select Ford, Lincoln, and Mercury applications. It is built for drivers who need consistent brake assist and a firm, predictable pedal feel in daily driving conditions.

Product Details

MPA Electrical’s Reman Vac Pwr Brake Booster w/o Master Cyl line focuses on replacement boosters that are tested for vacuum seal integrity and pressure transfer. This B1152 unit is remanufactured with specially treated components and is end-of-line tested to verify performance before release. For Ford Explorer, Lincoln Aviator, and Mercury Mountaineer brake repair jobs, B1152 provides a direct replacement path when the original vacuum booster has lost assist or developed internal leakage.

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

Common Problems This Part Can Address

  • Hard brake pedal feel
  • Reduced brake assist from vacuum loss
  • Longer stopping distances caused by booster failure
  • Brake pedal effort that increases during normal driving
  • Internal diaphragm or seal wear in the original booster

Installation Notes

Verify master cylinder compatibility, mounting stud thread size, and pedal rod setup before installation. Because the master cylinder is not included, transfer or replace related brake components as needed during service. Confirm fitment against the vehicle’s brake system configuration for 2002-2005 Ford Explorer, 2004-2005 Lincoln Aviator, or 2002-2005 Mercury Mountaineer.

Quality Assurance

MPA Electrical subjects each booster to 100% end-of-line testing using proprietary equipment to confirm vacuum seal performance and pressure transfer. The remanufactured construction and tested output support consistent brake assist for the listed applications.
