2007 Toyota Tacoma Brake Booster Parts Q&A

• Q: How to service and repair the vacuum brake booster without VSC on 2007 Toyota Tacoma?

  A: The service and repair process of the vacuum brake booster requires first disconnecting the negative battery cable then draining brake fluid and cleaning all paint-contacted areas. All front floor footrests, front door scuff plates from Regular Cab and Access Cab and Double Cab models along with the cowl side trim boards from their specific configurations need to be taken off. Use the instrument panel under tray for automatic transmission or remove the instrument panel hole cover on manual transmission before proceeding to the instrument panel finish panel lower No. 1. Before removing the brake booster workers should detach the vacuum hose follow the disconnection of 4 nuts before pulling out the booster and gasket removal. Brake booster installation requires a new gasket which should be applied first before bolting the assembly using four nuts tightened to 14.2 Nm (145 kgf-cm, 10 ft. lbs.) while connecting the vacuum hose. The technician should reattach the master cylinder push rod clevis together with the brake master cylinder followed by brake fluid reservoir filling and complete master cylinder and brake line bleeding procedures. Examine the reservoir fluid level as well as check for brake fluid leaks and measure brake pedal height along with free play and reserve distance. The driver side junction block needs to be torqued to 8.0 Nm before reinstalling other components including the instrument panel finish panel lower No. 1, instrument panel under tray for automatic transmission, instrument panel hole cover for manual transmission, cowl side trim boards for each cab type, front door scuff plates for each cab type, and front floor footrest. Fasten the cable to the negative battery terminal before tightening it to 3.9 Nm (40 kgf-cm, 35 inch lbs.).
