Installation Notes and Tips

Verify master cylinder stud thread size, mounting stud count, and booster-to-firewall fitment before installation. Because the master cylinder is not included, transfer or replace related brake components as needed and inspect vacuum hoses, check valves, and pedal linkage for wear before final assembly. Confirm proper brake pedal travel and vacuum assist after installation.
