CAUTION / NOTICE / HINT
Note
While the auxiliary battery is connected, even if the power switch is off, the brake control system activates when the brake pedal is depressed or any door courtesy switch is turned on. Therefore, when servicing brake system components, do not depress the brake pedal or open/close the doors while the auxiliary battery is connected.
PROCEDURE
INSTALL BRAKE BOOSTER GASKET
Install a new brake booster gasket to the brake booster with master cylinder assembly.
INSTALL BRAKE BOOSTER WITH MASTER CYLINDER ASSEMBLY
| *a | Connector Portion |
| *b | Union |
| *c | Push Rod Clevis |
| *d | Boot |
| *e | Brake Tube |
Install the brake booster with master cylinder assembly with the 4 nuts.
Note
Do not kink or damage the brake tubes.
Do not carry the brake booster with master cylinder assembly by the portion shown in the illustration.
Be careful not to allow brake fluid to enter the connector of ECU.
If installing a new brake booster with master cylinder assembly, do not remove the hole plugs before connecting the brake lines because the brake booster with master cylinder is filled with brake fluid.
| *a | Torque Wrench Fulcrum Length |
Install the brake tube to the vehicle body with the grommet.
Using a 10 mm union nut wrench, connect the brake tube to the front flexible hose.
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 (6.37 in.)): 13.4 N*m (137 kgf*cm, 10 ft.*lbf)
Note
Do not kink or damage the brake tubes.
| *1 | Clamp |
| *2 | Brake Tube |
Set the brake line to the clamp as shown in the illustration.
Note
Securely install the brake line so that it contacts the clamp as shown in the illustration.
| *a | Torque Wrench Fulcrum Length |
Using a 10 mm union nut wrench, connect the 5 brake tubes to the brake booster with master cylinder assembly.
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 (6.37 in.)): 13.4 N*m (137 kgf*cm, 10 ft.*lbf)
Note
Do not kink or damage the brake tubes.
| *a | Stopper |
| *b | Torque Wrench Fulcrum Length |
Install the wire harness clamp bracket to the brake booster with master cylinder assembly with the bolt.
Note
Securely install the wire harness clamp bracket so that its stopper contacts the brake booster with master cylinder assembly as shown in the illustration.
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 (6.37 in.)): 11.4 N*m (116 kgf*cm, 8 ft.*lbf)

Connect the connector |
|
Lock the lock lever |
Connect the connector to the brake booster with master cylinder assembly.
Note
Make sure that the connector can be connected smoothly. Do not allow water, oil or dirt to enter.
Make sure that the connector lock is locked securely.
Engage the clamp to install the motor compartment main wire.
CONNECT BRAKE MASTER CYLINDER RESERVOIR WITH BRACKET
| *1 | No. 1 Reservoir Hose |
| *2 | No. 2 Reservoir Hose |
| *3 | No. 2 Brake Actuator Hose |
| *a | 120° |
| *b | 60° |
| *c | 30° |
|
Upper of Vehicle |
Connect the No. 2 brake actuator hose, No. 1 reservoir hose and No. 2 reservoir hose to the brake booster with master cylinder assembly and No. 1 brake actuator tube, and slide the 3 clips to secure them.
Note
Make sure to match the identification mark on the hose with the brake booster with master cylinder assembly rib.
| Item | Hose Identification Mark Color | Brake Booster with Master Cylinder Assembly Identification Mark Color |
|---|---|---|
| No. 1 Reservoir Hose | White | White (Unpainted Color) |
| No. 2 Reservoir Hose | Green | Green |
| No. 2 Brake Actuator Hose | Yellow | Yellow |
When connecting the reservoir hose, face the identification mark to the top of the vehicle.
Make sure to install the hose to the proper location.
Install the clip within the range shown in the illustration.
BLEED NO. 1 BRAKE ACTUATOR TUBE
Note
Make sure to bleed the air from the No. 1 brake actuator tube. If the air remains in the No. 1 brake actuator tube, the air enters into the brake booster pump assembly and it may cause the brake booster pump assembly to be damaged.
Remove the brake master cylinder reservoir filler cap assembly.
Add brake fluid into the reservoir between the MAX and MIN level on the brake fluid reservoir.
| Brake Fluid |
|---|
| SAE J1703 or FMVSS No. 116 DOT3 |
Install the brake master cylinder reservoir filler cap assembly.
Remove the nut, disengage the clamp and separate the No. 1 brake actuator tube from the vehicle body.
Lift up the brake master cylinder reservoir with bracket as far as possible.
Note
Do not spill the brake fluid.
While holding the brake master cylinder reservoir with bracket, twist and hold the No. 1 brake actuator tube 90° toward the vehicle front, and wait at 5 seconds.*1
Note
Do not damage the hoses.
Tech Tips
Keeping the No. 1 brake actuator tube twisted causes the remaining air inside the No. 1 brake actuator tube to be expelled to the brake master cylinder reservoir assembly.
Return the No. 1 brake actuator tube to its original state.
While holding the brake master cylinder reservoir with bracket, twist and hold the No. 1 brake actuator tube 90° toward the vehicle rear, and wait at 5 seconds.
Note
Do not damage the hoses.
Tech Tips
Keeping the No. 1 brake actuator tube twisted causes the remaining air inside the No. 1 brake actuator tube to be expelled to the brake master cylinder reservoir assembly.
Return the No. 1 brake actuator tube to its original state.*2
Repeat steps *1 to *2, 5 times.
While holding the brake master cylinder reservoir with bracket, pinch the brake actuator hose 10 times with your fingers.
Note
Do not use pliers or similar to pinch the brake actuator hose. Doing so may cause damage to the brake actuator hose. Make sure to use your fingers.
Repeat steps *1 to *2, 5 times again, and check that air is not expelled from the No. 1 brake actuator tube.
Engage the clamp and install the No. 1 brake actuator tube with the nut.
