Twist off the brake pushrod nut along with its washer before pulling the brake pushrod out through the Brake Pedal pivot. Unthread the vacuum Brake Booster nuts and the power brake vacuum booster unit from the body while replacing the gasket if damage is found during inspection. Start by placing the new gasket for the power brake vacuum booster onto position before putting the power brake vacuum booster . Apply high temperature grease gm p/n 12345996 into the Brake Pedal pushrod pin and position the nuts at the vacuum Brake Booster locations. Afterward tighten the nuts to 17 nm (14 lb ft). Put a thin layer of high-temperature grease gm part 12345996 on the Brake Pedal pushrod pin and join its ends together on the Brake Pedal pivot point. Place the Brake Pedal pushrod washer and nut over the rod and tighten the nut to 10 nm (89 lb in). Insert the vacuum power Brake Booster check valve and its hose onto the Brake Booster hole with a bit of denatured alcohol as a sealing aid if needed. Also join the vacuum power brake vacuum sensor electrical connector to the unit. Reattach the master cylinder and underhood electrical components following their previous installation positions.
