Installation [06/2015 - ]: Procedure

1. Install the 2 brake actuator bracket cushions to the brake actuator bracket assembly.
2. Install the brake booster pump assembly, 2 brake booster pump bushings and 2 brake actuator case collars to the brake actuator bracket assembly with the 2 nuts.

   Torque: 5.4 N*m (55 kgf*cm, 48 in.*lbf) 

   NOTE:

   • When handling the brake booster pump assembly, do not hold it at the parts marked *a, *b and *c in the illustration.
   • Do not drop the brake booster pump assembly when carrying it. Do not use a brake booster pump assembly that has been dropped.
   • Do not allow brake fluid to contact the inside of the connector.
   • When installing the brake booster pump assembly to the brake actuator bracket assembly, confirm that the 2 brake actuator bracket cushions are on the brake actuator bracket assembly, and brake booster pump bushing and brake booster pump collar are on the brake booster pump assembly.
   • Do not remove the hole plug before installing a new brake booster pump assembly because the brake booster pump assembly is filled with brake fluid.
