Title: BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: BRAKE ACTUATOR: INSTALLATION; 2016 - 2017 MY Sienna [12/2015 - 11/2017]

INSTALLATION

PROCEDURE

1. INSTALL BRAKE ACTUATOR ASSEMBLY

(a) Install the brake actuator to the brake actuator bracket assembly with the 3 bolts.

Torque:

5.4 N·m {55 kgf·cm, 48 in·lbf}

NOTICE:

Do not remove the hole plugs of a new brake actuator before connecting the 6 brake lines because the brake actuator is filled with brake fluid.
Do not hold the actuator by the connector.
Tighten the 3 bolts in the order shown in the illustration.

2. INSTALL BRAKE ACTUATOR WITH BRACKET

(a) Install the brake actuator with bracket to the body with the bolt and 2 nuts.

Torque:

19 N·m {194 kgf·cm, 14 ft·lbf}

NOTICE:

Do not damage the brake lines or wire harness.
Tighten the bolt and 2 nuts in the order shown in the illustration.

(b) Temporarily tighten each brake line to the correct positions of the brake actuator with bracket as shown in the illustration.

	Flare Nut A (10 mm)
	Flare Nut B (12 mm)

Torque:

Flare nut A (10 mm) :

15 N·m {155 kgf·cm, 11 ft·lbf}

Flare nut B (12 mm) :

20 N·m {199 kgf·cm, 14 ft·lbf}

NOTICE:

Use the formula to calculate special torque values for situations where the union nut wrench is combined with a torque wrench (See page ).

(d) Install the harness clamp.

(e) Connect the brake actuator connector.

NOTICE:

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.

(f) Install the air conditioner tube and accessory assembly to the body with the bolt.

Torque:

5.4 N·m {55 kgf·cm, 48 in·lbf}

NOTICE:

Be sure to insert the air conditioner tube and accessory assembly into the stopper hole while installing the air conditioner tube and accessory assembly.
Do not damage the air conditioner tube and accessory assembly.

(g) Install the harness clamp and connect the air conditioner pressure sensor connector.

3. FILL RESERVOIR WITH BRAKE FLUID

4. BLEED BRAKE MASTER CYLINDER

5. BLEED BRAKE LINE

6. BLEED BRAKE ACTUATOR

7. INSPECT FOR BRAKE FLUID LEAK

8. INSPECT FLUID LEVEL IN RESERVOIR

9. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL

NOTICE:

When disconnecting the cable, some systems need to be initialized after the cable is reconnected (See page ).

Torque:

5.4 N·m {55 kgf·cm, 48 in·lbf}
