About this part

Hydraulic Brake Booster for Chevrolet / GMC / Isuzu. A hydraulic brake booster uses power-steering pressure instead of vacuum to assist braking — common on diesel and heavy-duty trucks where engine vacuum is limited. 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.
