• Q: How to remove the Vacuum Brake Booster on 2008 Toyota Highlander?

  A: Saving time is possible for Vacuum Brake Booster removal when the brake booster vacuum is pushed out first while taking away the master cylinder. The process starts with removing the V-bank cover sub-assembly followed by uninstalling both front wiper arms with blades from their left and right positions. The maintenance process requires removal of the cowl top ventilator louver sub-assembly and the windshield wiper motor link and outer cowl top panel sub-assembly. The first step involves draining the brake fluid as well as removing the air cleaner cap sub-assembly to disconnect the No. 1 reservoir tube along with the brake line. The brake master cylinder sub-assembly should be removed before disconnecting the vacuum hose with its clip and extracting the brake vacuum check valve assembly and check valve grommet. Next move on to take away the brake pedal return spring followed by separating the brake master cylinder push rod clevis then complete the clevis removal by taking off four nuts while pushing out the brake booster assembly without causing harm to brake lines. Use a wrench to take off the lock nut and extract both brake master cylinder push rod clevis together with the lock nut which is attached to the brake booster assembly. The engine wire can be separated from the body by first disconnecting nine clamps and a bolt then separating the engine wire if needed by disconnecting the alarm horn connector. The end of the process involves dislodging the brake lines from their position on the body by removing two clamps before removing both the brake booster assembly and gasket. The procedure requires attention to avoid harming brake lines or clamps.
