Product Details

The Cardone Vacuum Power Brake Booster line focuses on restoring factory-style brake assist with remanufactured units that are inspected, re-engineered, and tested to original equipment standards.

  • Corrosion-related housing deterioration on the original unit

Installation Notes and Tips

Verify the vehicle is a 1997 Infiniti QX4 or a 1996-1997 Nissan Pathfinder that was built without a master cylinder before ordering. Confirm the master cylinder stud thread size is M8 x 1.25 and compare the original booster layout, diaphragm style, and mounting points before installation. Follow the included instruction manual and inspect vacuum connections, pushrod alignment, and brake system operation after installation.
