This thrust works with the driver's input to push thebrake master cylinder, building hydraulic pressure that ultimately enables wheel brakingSpecification:1. Color: Black2.

• Replacement Part Number: 54-73565, 5473565, 8133909
• Fitment: Replacement for CJ5 1982-1983 L4 2.5L/L6 4.2L, replacement for CJ7 1982-1986 L4 2.5L/L6 4.2L/L6 4.6L, Replacement for Scrambler 1982-1985 L4 2.5L/L6 4.2L. It comes without Master Cylinder
• Function: The main function of the vacuum brake booster is to amplify the force applied by the driver to the brake pedal, reducing the effort required for braking and improving the efficiency of the braking response
• Reliable Design: The vacuum power brake booster is primarily composed of mechanical components, including a diaphragm, vacuum valve, atmospheric valve, and push rod. It has no complex electronic components, which contributes to its reliability
• Features: The vacuum brake booster directly utilizes the natural vacuum from the engine's intake system, without consuming additional fuel or electricity
