Product Details

The Cardone Vacuum Power Brake Booster line focuses on remanufactured brake boosters that are re-engineered from original designs and verified before release. Part number 54-74230 is built for Chrysler and Dodge applications that use a vacuum brake booster without a master cylinder included, and it cross-references Chrysler and Dodge OE numbers 4721613AA and 4721721AA for the same application.

This booster uses an M8 x 1.25 master cylinder stud thread size and includes the booster plus an instruction manual. It is a practical replacement for worn or leaking brake boosters on Chrysler Town & Country, Chrysler Voyager, Dodge Caravan, and Dodge Grand Caravan models from 2001 through 2007.

What It Can Help Fix

• Hard brake pedal feel caused by booster loss of vacuum assist
• Reduced braking assist during normal pedal application
• Vacuum leaks related to a failing brake booster diaphragm or check valve
• Brake response issues tied to worn internal booster seals
• Fitment problems when replacing an original booster on listed minivan applications

Installation Notes

Verify the vehicle uses a vacuum power brake booster and matches the listed Chrysler or Dodge application before installation. Confirm master cylinder stud thread size, pedal linkage alignment, and vacuum hose condition during service. Because this unit is remanufactured, inspect the mounting surface and surrounding brake components for wear or contamination before reassembly.

Quality Assurance

Cardone remanufactures this booster to original-equipment standards and tests every unit for fit and function before it leaves the factory. The rust-resistant finish, new seals, and check valves support consistent performance in daily driving conditions.
