Installation [08/2020 - 12/2021]: Procedure

1. Install the brake actuator bracket cushion to the brake actuator bracket assembly.

1. Install the No. 1 brake actuator case collar to the brake actuator bracket cushion.

1. Temporarily install the brake actuator assembly with the 2 nuts and bolt.
2. Fully tighten the 2 nuts and bolt in the order shown in the illustration.

   Torque: 6.5 N*m (66 kgf*cm, 58 in.*lbf) 

   NOTE:

   • Do not remove the hole plugs of a new brake actuator assembly before connecting the brake tubes because the brake actuator assembly is filled with brake fluid.
   • Do not hold the brake actuator assembly by the connector.
