PROCEDURE
INSTALL BRAKE ACTUATOR BOLT CUSHION
Install the 3 brake actuator bolt cushions to the brake actuator bracket assembly.
Install the 3 brake actuator case collars to the brake actuator bolt cushions.
Note
Make sure the brake actuator case collars are in full contact with the brake actuator bolt cushions.
INSTALL BRAKE ACTUATOR ASSEMBLY
Temporarily install the brake actuator assembly to the brake actuator bracket assembly with the 3 bolts.
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.
INSTALL BRAKE ACTUATOR WITH BRACKET
Temporarily install the brake actuator with bracket with the 2 bolts and nut.
Note
Do not damage the brake lines.
Do not hold the brake actuator with bracket by the connector.
Tech Tips
Install the brake actuator with bracket while avoiding the brake lines.
Tighten the 2 bolts and nut in the order shown in the illustration.
| *a | To Front Wheel Cylinder Assembly LH |
| *b | To Rear Wheel Cylinder Assembly RH |
| *c | To Rear Wheel Cylinder Assembly LH |
Temporarily connect the 3 brake lines to the correct positions on the brake actuator assembly as shown in the illustration.
| *a | Torque Wrench Fulcrum Length |
| *b | Union Nut Wrench |
Using a union nut wrench, fully tighten each brake line.
Note
Do not kink or damage the brake lines.
Do not allow the brake lines to twist or interfere with other parts or the vehicle body during tightening.
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 22 mm (0.866 in.)) + torque wrench (fulcrum length of 162 mm (6.38 in.)):
13.4 N*m (137 kgf*cm, 10 ft.*lbf)

Connect the connector |
|
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.
INSTALL REAR NO. 1 BRAKE TUBE
| *a | Torque Wrench Fulcrum Length |
| *b | Union Nut Wrench |
Engage the clamp to install the rear No. 1 brake tube.
Using a union nut wrench, connect the rear No. 1 brake tube to the brake actuator assembly.
Note
Do not kink or damage the rear No. 1 brake tube.
Do not allow the rear No. 1 brake tube to twist or interfere with other parts or vehicle body during tightening.
Do not allow any foreign matter such as dirt or dust to enter the rear No. 1 brake tube 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.)):
17.4 N*m (177 kgf*cm, 13 ft.*lbf)
INSTALL FRONT NO. 1 BRAKE TUBE
| *a | Torque Wrench Fulcrum Length |
| *b | Union Nut Wrench |
Engage the clamp to install the front No. 1 brake tube.
Using a union nut wrench, connect the front No. 1 brake tube to the brake actuator assembly.
Note
Do not kink or damage the front No. 1 brake tube.
Do not allow the front No. 1 brake tube to twist or interfere with other parts or vehicle body during tightening.
Do not allow any foreign matter such as dirt or dust to enter the front No. 1 brake tube 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.)):
17.4 N*m (177 kgf*cm, 13 ft.*lbf)
CONNECT UNION TO CHECK VALVE HOSE
Connect the union to check valve hose to the brake booster assembly and slide the clip to secure it.
INSTALL FRONT NO. 2 BRAKE TUBE
| *1 | Front Flexible Hose |
| *2 | Grommet |
| *a | Torque Wrench Fulcrum Length |
| *b | Union Nut Wrench |
Install the front No. 2 brake tube to the vehicle body, and engage the grommet.
Note
Do not kink or damage the front No. 2 brake tube.
Do not allow any foreign matter such as dirt or dust to enter the front No. 2 brake tube from the connecting parts.
Ensure that the front No. 2 brake tube passes through the center of the grommet.
Using a union nut wrench, connect the front No. 2 brake tube to the front flexible hose while holding the flexible hose with a wrench.
Note
Do not allow the front No. 2 brake tube to twist or interfere with other parts or the vehicle body during tightening.
Tech Tips
