This part cross-references OE numbers F9ZZ2B559AA and XR3Z2005AA for the same application.

Common Problems This Part Can Address

• Hard brake pedal feel
• Reduced brake assist
• Loss of hydraulic booster performance
• Brake response inconsistency during stopping
• Replacement of a worn or leaking booster assembly

Installation Notes

Verify the vehicle uses a hydraulic booster setup before ordering. Confirm master cylinder stud thread size, mounting bracket alignment, and pedal linkage condition during installation. Because the master cylinder is not included, reuse or replace the master cylinder separately as needed and inspect related brake system components for wear, leaks, or contamination before returning the vehicle to service.

Quality Assurance

MPA Electrical subjects each booster to 100% end-of-line testing using proprietary equipment to verify performance before release. The remanufactured construction and treated components are used to support sealing, pressure transfer, and braking assist consistency in Ford Mustang applications.
