• Q: How to install the brake booster on 2009 Scion tC?

  A: The first step to install the brake booster requires fitting a new gasket onto the brake booster body. You must attach the brake booster grommet to the brake booster along with the check valve followed by installing 4 nuts and tightening them to 12.7 Nm (130 kgf-cm, 9 ft-lbf. After connecting the vacuum hose with a clamp to the brake booster you must install the push rod clevis and locked nut following brake pedal height adjustment through proper torque adjustment of the clevis lock nut. Secure the three brake tubes to clamps by using additional clamps. Use Special Service Tool: 09023-00101 to connect the No. 5 front brake tube and torque it to 15 Nm (155 kgf-cm, 11 ft-lbf) when not using the tool or 14 Nm (143 kgf-cm, 10 ft-lbf) when using it with a torque wrench including a 30 cm (11.81 in.) fulcrum length. The grommet needs to be properly installed. The front wheel LH requires installation with torque set at 103 Nm (1,050 kgf-cm, 76 ft-lbf). The technician must complete installation of the brake master cylinder sub-assembly and the air cleaner cap sub-assembly before proceeding to fit the lower cowl body mounting bracket LH and the No. 1 cowl water extract hose and outer cowl top panel sub-assembly. Attach the brake master cylinder push rod clevis followed by fluid addition to the reservoir before bleeding air from the brake master cylinder system. You must check brake pedal elevation followed by brake travel distance and pedal cushion distance before testing brake fluid level in the reservoir tank while also inspecting for leakage. The final assembly includes windshield wiper motor and link installment with cowl top ventilator louver LH and hood to cowl top seal fitting together as well as windshield wiper arm and blade assemblies LH and RH and front wiper arm head cap installation.
