Power Brake Booster: Removal

NOTE: Power brake booster can be removed without completely removing master cylinder, but if both components are to be removed, remove master cylinder first.
  1. On 3.4L models, remove upper intake manifold. See 3.4L DOHC V6 article in ENGINES section. On all models, remove nuts securing master cylinder to booster. Remove transmission fill tube (if equipped). Without disconnecting hydraulic lines, remove master cylinder from booster and position aside. Disconnect vacuum hose from booster check valve.
  2. Attach Power Brake Booster Holder (J-22805-01) to booster. Using screwdriver, pry locking tab on booster out of locking notch on mounting flange. Turn booster counterclockwise with wrench attached to power brake booster holder.
  3. Disconnect push rod from brake pedal, being careful not to damage brake light switch. Remove booster. DO NOT damage insulator boot when pulling push rod through hole in firewall.
