Product Details

Cardone Vacuum Power Brake Booster 54-71150 is engineered for brake systems that require consistent vacuum assist and OE-style operation. This remanufactured booster uses a single diaphragm layout and a steel housing, and it is finished in gray for a clean replacement appearance. The unit is supplied without a master cylinder and includes the booster and instruction manual.

This part cross-references Chevrolet and GMC OE number 18010580 for the same application. It is a direct-fit choice for 1981-1989 Chevrolet G10 and 1981-1989 GMC G1500 vans when the vehicle is equipped with brake code JB3 and a single diaphragm booster.

What It Helps Fix

• Hard brake pedal feel
• Reduced brake assist from a failing vacuum booster
• Brake response issues caused by internal diaphragm wear
• Vacuum leaks at the booster assembly
• Fitment problems when replacing an OE-style booster on GM vans

Installation Notes

Verify the brake code on the Service Parts Identification sticker before ordering. This booster is for vehicles without a master cylinder and with a single diaphragm booster configuration. Confirm the master cylinder stud thread size is M10x1.5 and compare the original booster dimensions before installation. For 1981-1989 Chevrolet G10 and 1981-1989 GMC G1500 applications, match the vehicle’s brake code JB3 and vacuum booster setup to ensure correct installation.
