Product Details

The Cardone 54-74431 is a remanufactured power brake booster for vehicles that use vacuum-assisted braking without a master cylinder. It is built with a dual diaphragm, steel housing, and M10x1.5 master cylinder stud thread size. The booster is intended for direct replacement where the original unit has lost assist, developed vacuum leakage, or no longer delivers consistent pedal feel. This part cross-references Chevrolet and GMC OE part number 15886470 for the same application.

What It Helps Fix

• Hard brake pedal caused by weak or failed vacuum assist
• Reduced stopping response from a leaking booster diaphragm
• Brake pedal effort that feels inconsistent or excessive
• Vacuum loss related to booster wear or seal failure
• Replacement needs after corrosion or housing deterioration

The booster is supplied without a master cylinder, and the existing brake system should be inspected for vacuum supply, mounting condition, and pedal linkage wear during installation.
