• Q: How to remove the Vacuum Brake Booster on 2009 Toyota Highlander?

  A: The first step to remove the Vacuum Brake Booster requires releasing vacuum through brake pedal depression multiple times followed by separating the brake master cylinder from its assembly connection. With the removal of components from the 1AR-FE engine the No. 1 engine cover sub-assembly and ejector tube need to be taken off. Both engine types require disassembly of front wiper arm and blade assemblies (LH and RH) following by separation of cowl top ventilator louver sub-assembly, windshield wiper motor and link and outer cowl top panel sub-assembly. During the 1AR-FE procedure you need to remove the air cleaner cap combined with filter element sub-assemblies while the 2GR-FE requires elimination of its air cleaner cap and filter element. First drain brake fluid then disconnect the No.1 reservoir tube, brake line and remove the brake master cylinder sub-assembly. Remove the vacuum hoses from the 1AR-FE by sliding off the clips before taking out two nuts securing the vacuum assembly and then separating the vacuum check valve assemblies and check valve grommets from the brake booster. The vacuum hose removal process for the 2GR-FE requires disconnecting it while you also remove the vacuum check valve assembly together with its check valve grommet. First remove the brake pedal return spring then separate the brake master cylinder push rod clevis followed by pushing out the brake booster assembly through four nut removal. Go ahead and free the lock nut before you can extract the brake master cylinder push rod clevis along with its lock nut from the brake booster assembly. Separate the engine wire from the body using nine clamps while you also disconnect the alarm horn connector if needed. The two clamps need to be unlocked for removing the brake lines from the body while the team extracts both the brake booster assembly and brake booster gasket. Handle the brake lines and clamps with care because brake line damage will require new replacement parts.
