• Q: How to remove the Vacuum Brake Booster on 2009 Scion xD?

  A: The process to remove the Vacuum Brake Booster starts by releasing vacuum by repetitive brake pedal depression followed by removing the brake master cylinder from the brake booster. Drop the brake fluid while thoroughly cleaning all fluid which reaches painted objects. Start by discarding the front wiper arm head cap then take out both front wiper arm and blade assemblies present on their respective left and right sides. The hood to cowl top seal and both cowl top ventilator louver sub-assemblies as well as the left cowl top ventilator louver should get removed. Remove the front wiper motor and link together with the front air shutter seal on the right side and the outer cowl top panel. Start by taking out the battery and battery tray and afterward the battery carrier. Operators should disconnect the clutch reservoir tube prior to the brake master cylinder sub-assembly removal for manual transaxle vehicles. The service technician must separate the brake actuator assembly from the vehicle even though the vehicle has VSC and VSC is disabled, and the No. 1 instrument panel under cover sub-assembly. After you remove the instrument panel under tray you must separate the brake master cylinder push rod clevis. Finish installation by using a union nut wrench to disassemble brake tubes through the flexible hose holding position then taking out both grommets and brake tubing. The process begins with usage of a union nut wrench to detach brake tubes and remove the brake booster assembly by disconnecting the vacuum hose from its check valve after unscrewing all four nuts keeping the tubes unhurt. First remove the brake booster assembly gasket followed by lock nut loosening of the push rod clevis to extract the push rod. The brake vacuum check valve assembly together with its grommet must be detached from the brake booster assembly.
