2008 Toyota Corolla Brake Booster Parts Q&A

• Q: How to install the brake booster assembly on 2008 Toyota Corolla?

  A: Begin by installing the grommet followed by checking the valve assembly after which install a new brake booster gasket on top of the brake booster assembly. The installation process begins by connecting the push rod clevis along with its lock nut to the brake booster assembly. After adjusting the brake pedal height, torque the lock nut correctly. Fasten 4 brake booster assembly nuts to 12.7 Nm while tightening them to 130 kgf-cm before connecting the brake tubes to the clamp with 2 or 3 tubes. Attach the vacuum hose to the brake booster assembly and connect the front brake tube No. 5 with Special Service Tool: 09023-00101 while maintaining correct grommet installation and torquing the tube to 15 Nm (155 kgf-cm, 11 ft-lbf). The front wheel LH needs to be installed with 103 Nm (1,050 kgf-cm, 76 ft-lbf) torque followed by attaching the brake master cylinder push rod clevis. The brake master cylinder sub-assembly installation requires 3 bolts for mounting, after which you should install the air cleaner element. The next step is to mount the air cleaner cap sub-assembly followed by brake fluid addition into the reservoir. The operator should begin bleeding the master cylinder alongside the brake line. Test and modify the brake pedal height and its free play and reserve distance then inspect the reservoir fluid level. The inspection should include a search for brake fluid leaks together with examination of the brake booster assembly.
