Product Details

Cardone’s Vacuum Power Brake Booster line focuses on restoring factory brake assist with remanufactured units that are re-engineered and tested before release. For this application, the 53-2547 uses an 8.285-inch (210.439 mm) diaphragm diameter, M8 x 1.25 master cylinder stud thread size, and a dual diaphragm style to support consistent pedal assist. The booster is supplied without a master cylinder and includes the booster plus an instruction manual.

This part cross-references Infiniti 4721064J20 and 4721064J22, as well as Nissan 472101E600, for the same application.

Common Brake Assist Problems It Can Address

• Hard brake pedal feel from reduced vacuum assist
• Longer stopping distances caused by booster performance loss
• Brake pedal effort that increases over time
• Corrosion-related booster housing deterioration
• Fitment issues when replacing a worn original booster on Nissan Altima or INFINITI G20 models

Installation Notes and Tips

Verify vehicle fitment by year, make, model, and the note that the application is for vehicles lacking master cylinders before installation. Inspect vacuum lines, check valves, and the master cylinder condition during service, since related wear can affect brake assist performance. Confirm the master cylinder stud thread size and output rod setup match the vehicle’s brake system before final assembly.

Quality Assurance

Each Cardone remanufactured power brake booster is re-engineered and 100% tested to help ensure proper fit and function. The unit is built to OE performance standards and finished with a rust-prohibitive coating to support service life.
