Brake Actuator: Installation

1. Install the actuator bracket with the 2 nuts.

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

   NOTE: Do not remove the hole plug before connecting the brake tube. New actuators are filled with brake fluid.

4. Using SST, install each brake tube into the correct position of the actuator, as shown in the illustration.

   SST 09023-00100 

   Torque: 

   for use without SST 

   15 N*m (155 kgf*cm, 11 ft.*lbf) 

   for use with SST 

   14 N*m (143 kgf*cm, 10 ft.*lbf) 

   HINT:

   • Use a torque wrench with a fulcrum length of 300 mm (11.81 in.).
   • This torque value is effective when SST is parallel to a torque wrench.
