2009 Toyota Tacoma Parts Questions & Experts Answers

• Q: How to remove and replace the hydraulic brake booster on 2009 Toyota Tacoma?

  A: A replacement procedure for the hydraulic brake booster starts with turning off the ignition switch and performing more than 20 brake pedal depressions before work begins. High pressure must not cause deformation to brake actuator tube No. 1 during the operation and the ignition switch should remain OFF until the work is finished. First disconnect the negative battery terminal cable and drain the brake fluid before immediately cleaning painted surfaces touched by fluid. You need to take out the front floor footrest as well as the front door scuff plates which exist for Regular Cab, Access Cab, and Double Cab and the cowl side trim boards that belong to each cab variation. Begin by taking out the automatic transmission instrument panel under tray or the manual transmission instrument panel hole cover followed by the instrument panel finish panel lower No. 1. Two procedures must take place: the separation of driver side junction block from master cylinder push rod clevis then proceeding with their disconnection. The technician should disconnect 3 connectors from the hydraulic brake booster before using a union nut wrench to separate the 4 brake lines which require labeling for future reconnection. Finally, remove the 4 nuts to extract the hydraulic brake booster together with its brake booster gasket.
