• Q: How to install the brake master cylinder on 2008 Toyota Yaris?

  A: Start installation of the brake master cylinder by inspecting and setting Special Service Tool: 09737-00013 against the master cylinder to access the brake booster push rod. Then adjust the push rod length until it touches the piston to finalize brake booster push rod adjustment. The brake master cylinder can be installed using the alternative tool: Special Service Tool: 09737-00012. The installation process requires measuring the tool clearance against the brake booster push rod with chalk on its flat tip by turning the tool upside down and ensuring the reading fits within -0.21 to 0 mm (-0.0083 to 0 in.) standard range. The rod length should be adjusted using Special Service Tool: 09737-00020 while holding it between the 7 mm socket driver and the tip of the rod then verify the clearance afterward. You should now install a new O-ring onto the brake master cylinder. When installing the brake master cylinder with ABS models use two nuts which require a torque setting of 13 Nm (127 kgf-cm, 9 ft-lbf). To install the brake master cylinder and brake tube way you must use the specified torque value for both models. Connect Special Service Tool: 09023-00100 to install the 2 brake tubes onto the brake master cylinder, deliver a torque of 15 Nm (155 kgf-cm, 11 ft-lbf) when using the tool and 14 Nm (143 kgf-cm, 10 ft-lbf) when using the tool, followed by confirming that the torque wrench lies at a 300 mm (11.81 in.) fulcrum length and runs parallel to the tool. To install brake tubes on brake tube ways of models without ABS employ Special Service Tool: 09023-00100 while applying necessary torque values. Complete the linkage between the brake fluid level warning switch and connect the clutch reservoir tube with its clip. The technician must first install the battery carrier and battery tray then add brake fluid to the reservoir before performing the master cylinder and brake line bleeding procedure and checking the fluid level alongside inspecting for any fluid leakages.
