2008 Toyota Tacoma Brake Booster Parts Q&A

• Q: What steps should be taken before starting the work on the hydraulic brake booster on 2008 Toyota Tacoma?

  A: Begin entering the work session with the ignition switch OFF and apply more than twenty resets to the brake pedal. During brake actuator tube No. 1 high pressure application avoid altering its shape while keeping the ignition switch in OFF position during the entire work period. The stroke extends in length after accumulator pressure reduces because the reaction force lowers its weight. First disconnect the negative battery cable then drain brake fluid yet wash off paint-contacted fluid immediately. The footrest on the front floor, front door scuff plates in all cab variants, and the cowl side trim boards in all cab types should be detached. Begin by removing the instrument panel under tray used for automatic transmission then proceed to take off the instrument panel hole cover for manual transmission followed by the instrument panel finish panel lower No. 1. The driver side junction block and the master cylinder push rod clevis need to be divided apart. The last step involves disconnecting the 3 connectors from the hydraulic brake booster followed by using a union nut wrench to separate the 4 brake lines while making labels for reinstallation. Next remove the 4 nuts and pull out the hydraulic brake booster system together with its gasket.
