Product Details

Cardone Vacuum Power Brake Booster 54-73190 is part of the Cardone remanufactured brake booster line, which focuses on restoring original braking performance through inspection, re-engineering, and testing. This unit uses a dual diaphragm with an 8.76-inch diaphragm diameter and an M8 x 1.25 master cylinder stud thread size. It is remanufactured from steel and finished in gray for a clean, corrosion-resistant appearance.

This part cross-references Ford and Mercury applications such as F1VY2005B and F4AZ2005B for the same application.
