Detailed Description

Cardone 53-2775 is a remanufactured vacuum power brake booster engineered for direct replacement in select Toyota applications. It is built to restore brake pedal assist by using engine vacuum to reduce pedal effort, helping the braking system respond more consistently under normal driving conditions. This unit is compatible with 1988-1989 Toyota 4Runner and 1988 Toyota Pickup models that lack master cylinders, making it a focused solution for those specific brake system configurations. This part cross-references Toyota (e.g., 446103D060, 446103D260) for the same application.

Common Issues This Part May Address

• Hard brake pedal feel caused by weak vacuum assist
• Reduced braking assist during normal stop-and-go driving
• Brake booster leakage from worn internal components
• Corrosion-related booster housing deterioration
• Fitment problems when replacing an original Toyota booster

Installation Notes and Tips

Verify the vehicle’s brake system configuration before installation, especially on 1988-1989 Toyota 4Runner and 1988 Toyota Pickup applications noted as lacking master cylinders. Confirm the master cylinder stud thread size is M8 x 1.25 and compare the original booster dimensions, including the 9.439-inch diaphragm diameter, before assembly. Follow the included instruction manual and inspect vacuum lines, check valves, and mounting surfaces during replacement.
