Product Details

The Cardone Vacuum Power Brake Booster line focuses on restoring factory-style brake assist with remanufactured components that are re-engineered and tested before release. Part number 54-71045 uses a dual diaphragm layout to support consistent vacuum-assisted braking, and it is supplied without a master cylinder. This booster is a direct replacement for select GM rear-wheel-drive platforms, including Cadillac Brougham, Chevrolet Caprice, and Oldsmobile Custom Cruiser applications that use a vacuum switch port.

This part cross-references Cadillac 18006566 and Oldsmobile 18008695 for the same application.

What It Helps Fix

• Hard brake pedal feel caused by a weak or leaking booster
• Reduced brake assist during normal stopping
• Vacuum loss related to booster diaphragm or check valve wear
• Brake response issues on aging GM full-size vehicles
• Fitment problems when replacing an original vacuum switch port booster

Installation Notes

Verify that the vehicle uses a vacuum switch port and that the master cylinder is not included with the replacement. Confirm the master cylinder stud thread size is M10x1.5 before installation. For best results, compare the original booster configuration, mounting points, and vacuum connections on the vehicle before removal.
