Removal and InstallationINFOID:0000000001691410
REMOVAL
Be careful of the following.
CAUTION:
 Before servicing, disconnect the battery cables.
 To remove brake tube, use a flare nut wrench to prevent flare nuts and brake tube from being dam-
aged. To install, use a flare nut torque wrench and tighten to the specified torque.
 Do not apply excessive impact to the actuator, such as dropping it.
INSTALLATION
Be careful of the following.
 When setting the actuator in the bracket, push it in until it locks.
 Tighten the mounting bolts and nuts to the specified torque.
 After the work, breed the air from the brake piping. Refer to BR-8, "
Bleeding Brake System".
 After installing the vehicle harness connector in the actuator, make sure the connector is securely locked.
