What It Helps Address

• Reduced brake assist from a worn hydraulic booster
• Brake response issues caused by internal seal wear
• Leaks at the booster assembly or related O-ring sealing points
• Fitment problems from a damaged or incorrect replacement booster

Installation Notes and Tips

Confirm hydro-boost system type, brake code, and master cylinder configuration before installation. This booster is listed without a master cylinder, so reuse or replace related components as needed based on the vehicle setup. Verify the master cylinder stud thread size is M10 x 1.50 and follow the included instruction sheet during installation. For 1994 Chevrolet and GMC trucks with brake codes JB8 or JD7, check the Service Parts Identification sticker to confirm the correct application.
