Product Details

Cardone’s Vacuum Power Brake Booster line focuses on remanufactured brake assist components that are inspected, re-engineered, and tested before release. The 54-71124 follows that approach with attention to original design, fitment, and consistent pedal response. For Jeep Cherokee, J10, J20, and Wagoneer models in the listed years, this booster provides a service replacement that aligns with factory-style operation.

This part cross-references Jeep 8124539 and 8126952 for the same application.

Confirm master cylinder stud thread size is M10x1.5 and compare the original booster dimensions and mounting points before installation. Follow the included instruction manual and inspect vacuum lines, check valves, and related brake components during service.
