About this part
Vacuum Booster for Buick / Chevrolet / Oldsmobile +1 makes. A vacuum booster multiplies pedal force using engine vacuum for lighter, more consistent braking — a failing one usually shows up as a hard pedal and longer stops. Brand-new unit — not a remanufactured core. OE and Cardone numbers are used only as a cross-reference, so you can order by a number you already know. Shown in real product photos.
VACTIRO confirms fitment by VIN or OE before any quote is issued. No payment is requested until availability, price and return terms are confirmed.
