Product Details

The Cardone Vacuum Power Brake Booster line focuses on restoring factory-style brake assist with remanufactured components that are re-engineered and verified before release. Part number 54-71929 uses a dual diaphragm style with a 9.56-inch diaphragm diameter and an M8 x 1.25 master cylinder stud thread size. The package includes the booster, an instruction manual, and an M/C neck seal. This part cross-references Saturn 25878055 for the same application.

Common Brake Assist Issues

• Hard brake pedal feel
• Reduced vacuum assist during braking
• Longer stopping distances caused by weak booster performance
• Brake pedal response that no longer feels consistent
• Replacement needs after booster wear, corrosion, or internal seal failure

Installation Notes

Verify vehicle application before installation, especially for 2008-2012 Chevrolet Malibu, 2008-2010 Pontiac G6, and 2009 Saturn Aura models listed as lacking master cylinders. Confirm master cylinder fitment, vacuum hose condition, and pushrod adjustment during service. Part number 54-71929 is designed for direct replacement use, but proper brake bleeding and system inspection should be completed after installation.
