• Q: How to install the brake master cylinder on 2009 Toyota Yaris?

  A: Installation of the brake master cylinder begins with brake booster push rod inspection and adjustment through the use of Special Service Tool: 09737-00013 which should be positioned on the master cylinder sub-assembly while lowering the rod to just touch the piston. Check the standard clearance between the brake booster push rod and tool with the chalked flat rod tip by measuring the space from 0 - 0.21 mm (-0.0083 to 0 in.). You can adjust the rod by using Special Service Tool: 09737-00020 to hold it followed by turning the rod tip using a 7 mm socket driver then re-checking the clearance. The installation process for the brake master cylinder sub-assembly with ABS requires a new O-ring that must be secured using 2 nuts at 13 Nm (127 kgf-cm, 9 ft-lbf). The brake tubes should be connected using a union nut wrench with a torque of 14 Nm (144 kgf-cm, 10 ft-lbf) or 15 Nm (155 kgf-cm, 11 ft-lbf) when without it. The warning switch connector must be connected to its housing. When installing an assembly without ABS maintain identical O-ring procedure while tightening two nuts to 13 Nm torque (127 kgf-cm, 9 ft-lbf) for the assembly and brake tube way and securely attaching brake tubes with corresponding torque values. Register the brake fluid level warning switch connector for a second time. The process includes tubing the clutch reservoir through the clip before putting up battery items and brake fluid wetting. An end to the brake fluid bleeding process requires inspecting the reservoir fluid level and checking for potential brake fluid leaks.
