Brake Booster

As the first step toward installing the hydraulic brake booster you must position a new brake booster gasket onto the unit before tightening the four nuts to 14 Nm (145 kgf-cm, 10 ft-lbf). Use a union nut wrench to attach the 4 brake lines at their correct positions on the hydraulic brake booster. Torque them to 15 Nm (155 kgf-cm, 11 ft-lbf) while the wrench is absent or to 14 Nm (145 kgf-cm, 10 ft-lbf) when using the torque wrench which should remain parallel to the tool. Connect three connectors then install the master cylinder push rod clevis followed by driving the driver side junction block to 8.0 Nm (82 kgf-cm, 71 in-lbf). Finish the work by installing the lower No. 1 instrument panel finish panel and the instrument panel under tray for automatic transmission as well as the instrument panel hole cover for manual transmission. Install the cowl side trim board LH for Regular Cab, Access Cab, Double Cab while moving onto the front door scuff plate LH and then the front floor footrest. To finish the repair, apply torque of 3.9 Nm (40 kgf-cm, 35 in-lbf) to the negative battery terminal cable while performing inspections of brake pedal height and free play and reserve distance and filling the reservoir with brake fluid followed by bleeding procedures for the brake booster using the accumulator pump assembly and the brake line then master cylinder solenoid and finally checking fluid levels and inspecting for leakage and brake master cylinder operation.

Remove the 4 nuts and pull out the hydraulic brake booster along with the brake booster gasket.
