Location: 
Mounted between the brake pedal linkage / master cylinder and the firewall, inside the engine bay, it provides vacuum assist to the master cylinder.

This brake vacuum booster helps multiply your braking power, making the pedal easier to press while ensuring smooth, safe, and reliable stopping performance.

Why replacement matters:
Over time, original boosters may develop internal leaks, diaphragm deterioration, or loss of vacuum integrity, leading to a hard brake pedal and diminished braking assistance
•  A failing booster reduces braking efficiency, making stops less responsive and potentially dangerous
•  Replacing ensures the correct internal design, vacuum chamber dimensions, diaphragm strength, and sealing to match the original factory part
•  Avoids costly repairs or unsafe driving conditions due to degraded brake assist
