Product Details

Cardone Hydro-Boost Power Brake Booster 52-7404 is part of the Cardone remanufactured brake booster line, which focuses on restoring original hydraulic brake assist performance through re-engineering, inspection, and testing. This unit uses a cast iron housing, M10 x 1.50 master cylinder stud thread size, and a black rust-resistant finish. It is a direct-fit replacement for select Chevrolet Express 1500 and GMC Savana 1500 vans, making it a practical choice when replacing a worn hydro-boost unit on GM full-size vans.

This part cross-references GMC 25790710 for the same application.

What It Helps Address

• Hard brake pedal feel caused by a failing hydro-boost unit
• Reduced brake assist from internal seal or valve wear
• Brake performance issues related to hydraulic booster leakage
• Fitment problems from an incorrect replacement booster
• Corrosion-related housing deterioration on older brake boosters

Installation Notes and Tips

Verify that the vehicle is equipped with a hydro-boost system and does not use a master cylinder before ordering. Confirm the master cylinder stud thread size, hydraulic connections, and mounting points against the original unit. Follow the included instruction sheet, replace the O-rings during installation, and bleed the brake system according to factory service procedures after installation.

Quality Assurance

Each Cardone remanufactured power brake booster is tested to confirm proper operation, fit, and function. The original design is inspected for improvement opportunities, and design updates are used where applicable to improve durability over the original part.
