Detailed Description

The Cardone 54-73207 power brake booster uses a dual diaphragm layout with a 7.415-inch diaphragm diameter and a steel housing. It is remanufactured to restore vacuum assist in vehicles that use a vacuum power brake booster without a master cylinder. This part number is used across multiple Ford and Mercury platforms, including 1984-1993 Ford Mustang, 1983-1986 Ford LTD, 1984-1986 Mercury Capri, and 1983-1986 Mercury Marquis. This part cross-references Ford and Mercury OE numbers such as D9ZZ2005A and E1BZ2005B for the same application.

What This Part Helps Address

• Hard brake pedal feel caused by a weak or failing booster
• Reduced brake assist during normal driving or stop-and-go traffic
