Detailed Description

The Cardone 54-71515 power brake booster is remanufactured from original design specifications and inspected for potential improvements during the rebuild process. Its dual diaphragm construction and 10.566-inch diaphragm diameter support consistent vacuum assist, while the steel body and protective finish add durability in demanding brake system environments. This part cross-references GM OE application 22745515 for the same application.

What It Helps Address

• Reduced brake assist during normal stopping
• Vacuum leak concerns at the booster assembly
• Brake system performance loss from worn internal seals

Installation Notes

Verify brake code and application details before installation, especially on JD9-equipped vehicles. This booster is for vehicles lacking master cylinders where specified, and the master cylinder is not included. Follow the instruction manual, inspect the mounting area and vacuum connections, and confirm the master cylinder neck seal is properly seated during assembly.
