Corvette 1985-91 Power Brake Unit

Pirate Jack PBU9013 – 1985–1991 Corvette 9" Power Brake Booster & Corvette-Style Master Cylinder | Replaces AC Delco 178-509

Get your C4 Corvette’s brakes sorted in one order. The PBU9013 pairs our brand-new 9" power brake booster (PB9013) with a matching Corvette-style master cylinder, so the booster and master arrive together, matched and ready to install. The booster is a direct replacement for AC Delco part number 178-509 and bolts in where your original came out.

Unlike boosters with plastic housings, the PB9013 booster in this kit is built with a metal housing for durability you can count on. Its clean black finish matches the factory look under the hood. The included Corvette-style master cylinder has a 1" bore with 9/16" and 1/2" ports and is set up for disc/drum brakes.

Brand new, never rebuilt. Every Pirate Jack power brake booster is brand new, vacuum tested and quality approved before it ships. Compare it with a remanufactured booster and you’ll see the difference: a new booster gives you better quality and value than a rebuilt core with unknown history.
