1. Install the rear disc brake cylinder assembly.
   

   NOTICE:

   Install the rear disc brake bush dust boot onto the groove of the rear disc brake cylinder.

1. Apply the lithium soap base glycol grease to the sliding part and the seal surface of the slide pin.
   

2. Install the rear disc brake cylinder slide pin No.1.
   

   Torque:

   43 N*m{ 440 kgf*cm , 32 ft.*lbf }

1. Apply the lithium soap base glycol grease to the sliding part and the seal surface of the slide pin No.2.
   

2. Install the rear disc brake cylinder slide pin No.2.
   

   Torque:

   43 N*m{ 440 kgf*cm , 32 ft.*lbf }

1. Connect the flexible hose with the union bolt and a new gasket.
   

   Torque:

   29 N*m{ 300 kgf*cm , 21 ft.*lbf }

1. Add brake fluid to the MAX line in the reservoir.
   

   Fluid:

   SAE J1703 or FMVSS No. 116 DOT3
   

   CAUTION:

   1. Add brake fluid carefully and check that the reservoir level remains between the MIN and MAX lines while bleeding the brakes.
      
   2. Do not stand the fluid can on the reservoir inlet when bleeding the brake actuator. Doing so will cause brake fluid to overflow.
      

CAUTION:

Never bleed air from the brake hydraulic system without using the intelligent tester. Failure to use the intelligent tester could cause serious injury or an accident.

NOTICE:

Bleed the air by following the steps displayed on the intelligent tester.

1. Connect the intelligent tester to the DLC3 with the ignition switch off.
   

2. Check that the parking brake is applied and turn the ignition switch to the ON position.
   

3. Turn on the intelligent tester and select "DIAGNOSTIC MENU"→"ABS/VSC"→"ECB UTILITY"→"ECB INVALID".
   

4. With the brake pedal depressed, bleed the rear brake system from the bleeder plug on the rear disc brake cylinder LH while the pump motor and solenoid are operating.
   

   CAUTION:

   Keep the fluid inside the reservoir above the LOW level by replenishing.

   HINT:

   1. Depress and hold the brake pedal.
      
   2. After the solenoid operates for approximately 30 seconds, release the brake pedal to stop the solenoid.
      
   3. Repeat the procedures until air is completely bled from the rear brake system.
      
   4. The ECB warning light comes on and the buzzer sounds while bleeding, but they do not indicate a malfunction.
      

5. Tighten the bleeder plug after bleeding.
   

   Torque:

   8.3 N*m{ 85 kgf*cm , 74 in.*lbf }

6. Turn the intelligent tester on and select "DIAGNOSTIC MENU"→"ABS/VSC"→"ECB UTILITY"→"ECB INVALID"
   

7. With the brake pedal depressed, bleed the rear brake system from the bleeder plug on the rear disc brake cylinder RH while the pump motor and solenoid are operating.
   

   CAUTION:

   Keep the fluid inside the reservoir above the LOW level by replenishing.

   HINT:

   1. Depress and hold the brake pedal.
      
   2. After the solenoid operates for approximately 30 seconds, release the brake pedal to stop the solenoid
      
   3. Repeat the procedures until air is completely bled from the rear brake system.
      
   4. The ECB warning light comes on and the buzzer sounds while bleeding, but they do not indicate a malfunction.
      

8. Tighten the bleeder plug after bleeding.
   

   Torque:

   8.3 N*m{ 85 kgf*cm , 74 in.*lbf }

CAUTION:

1. Never bleed air from the brake hydraulic system without using the intelligent tester. Failure to use the intelligent tester could cause serious injury or an accident.
   
2. Be sure to perform this procedure before replacement, removal, or installation of the actuator.
   

NOTICE:

Perform accumulator zero down by following the steps displayed on the intelligent tester.

1. Connect the intelligent tester to the DLC3 with the ignition switch off
   

2. Depressurize the accumulator.
   
   

   1. Check that the parking brake is applied and turn the ignition switch to the ON position.
      

   2. Turn on the intelligent tester and select "DIAGNOSTIC MENU" → "ABS/VSC" → "ECB UTILITY" → "ZERO DOWN" on the intelligent tester.
      

   3. When the buzzer sounds, turn the ignition switch off.
      

3. Circulate the fluid in the accumulator.
   
   

   1. Depressurize the accumulator 5 times.
      

      HINT:

      1. Accumulator pressure is released and accumulated repeatedly, which circulates the fluid inside the accumulator, when repeating accumulator zero down.
         
      2. The pump motor rotates and the accumulator is pressurized every time the ignition switch is turned from off to on.
         

1. After performing accumulator zero down (accumulator depressurizing), return the fluid in the accumulator back to the reservoir and then adjust the fluid level in the master cylinder reservoir to the MAX level.
   

   HINT:

   1. After performing accumulator zero down (accumulator depressurizing), fluid is built up in the accumulator by turning the ignition switch to the ON position and the fluid level of the reservoir lowers.
      
   2. If the fluid level is adjusted without performing accumulator zero down (accumulator depressurizing), fluid is sent from the accumulator to the reservoir. The fluid level may exceed the MAX level, but it is normal.
      

Torque:

103 N*m{ 1,050 kgf*cm , 76 ft.*lbf }
