Product Details

The Cardone Hydro-Boost Power Brake Booster line focuses on restoring hydraulic brake assist with remanufactured units that are inspected for design improvements where applicable. This approach helps deliver consistent pedal assist and dependable operation in vehicles that rely on hydro-boost braking rather than vacuum assist. Part number 52-7398 is built for applications using an M10 x 1.50 master cylinder stud thread size and includes a hydraulic booster, O-ring kit, and instruction sheet.

This part cross-references Chevrolet and Isuzu OE numbers for the same application, including Chevrolet 12377114 and Isuzu 19206594.

What It Helps Address

• Hard brake pedal feel from reduced hydraulic assist
