BRAKE ACTUATOR INSTALLATION

CAUTION / NOTICE / HINT

Tech Tips

The parking brake indicator light blinks (red) when the engine switch is turned on after replacing the brake actuator assembly. Operate the electric parking brake switch assembly to turn off the parking brake indicator light.

PROCEDURE


  1. INSTALL BRAKE ACTUATOR ASSEMBLY


    1. B005Q6KN01

      Install the brake actuator assembly to the brake actuator bracket assembly with the 3 bolts.

      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 lines because the brake actuator assembly is filled with brake fluid.

      • Do not hold the brake actuator assembly by the connector.

      • Tighten the 3 bolts in the order shown in the illustration.

  2. INSTALL BRAKE ACTUATOR WITH BRACKET


    1. Temporarily install the brake actuator with bracket with the bolt and 2 nuts.

      Note


      • Do not damage the brake lines.

      • Do not hold the brake actuator assembly by the connector.

      Tech Tips

      Install the brake actuator with bracket while avoiding the brake lines.

    2. Fully tighten the bolt and 2 nuts.

      Torque:
      19 N*m  { 194 kgf*cm, 14 ft.*lbf }
    3. B005ODRC01
      *a From 1st Chamber of Brake Master Cylinder Sub-assembly
      *b From 2nd Chamber of Brake Master Cylinder Sub-assembly
      *c To Front Wheel Cylinder Assembly RH
      *d To Rear Wheel Cylinder Assembly LH
      *e To Rear Wheel Cylinder Assembly RH
      *f To Front Wheel Cylinder Assembly LH

      Temporarily tighten the 6 brake lines to the correct positions on the brake actuator assembly as shown in the illustration.

    4. B005N4IC02
      *a Torque Wrench Fulcrum Length
      *b Union Nut Wrench

      Using a union nut wrench, fully tighten each brake line.

      Torque:
      Specified tightening torque (A)
      19.5 N*m  { 199 kgf*cm, 14 ft.*lbf }
      Specified tightening torque (B)
      15.2 N*m  { 155 kgf*cm, 11 ft.*lbf }

      Note


      • Do not kink or damage the brake lines.

      • Do not allow any foreign matter such as dirt or dust to enter the brake lines from the connecting parts.

      Tech Tips


      • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.

      • When using a union nut wrench (fulcrum length of 20 mm (0.787 in.)) + torque wrench (fulcrum length of 162 mm (6.38 in.)):

        (A): 17.36 N*m (177 kgf*cm, 13 ft.*lbf)

      • When using a union nut wrench (fulcrum length of 22 mm (0.866 in.)) + torque wrench (fulcrum length of 162 mm (6.38 in.)):

        (B): 13.38 N*m (136 kgf*cm, 10 ft.*lbf)

    5. B005Q1QC01
      B005OOA Connect the connector
      B005OMH Lock the lock lever

      Connect the connector to the brake actuator assembly and lock the lock lever.

      Note


      • Make sure that the connector is locked securely.

      • Make sure that the actuator connector can be connected smoothly. Do not allow water, oil or dirt to enter the connector.

  3. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL

    Note

    When disconnecting the cable, some systems need to be initialized after the cable is reconnected.
