Brake Fluid -- Bleeding

HINT:

If any work is performed on the brake system or if air in the brake lines is suspected, bleed the air from the brake system.

NOTICE:

Move the shift lever to the P position and apply the parking brake before bleeding the brakes.
Add brake fluid to keep the level between MIN and MAX lines of the reservoir while bleeding the brakes.
If brake fluid leaks onto any painted surface, wash off and remove it completely.

1. FILL RESERVOIR WITH BRAKE FLUID

Fill the reservoir with brake fluid.
Fluid:
SAE J1703 or FMVSS No. 116 DOT3

2. BLEED MASTER CYLINDER

HINT:

If the master cylinder is reinstalled or if the reservoir becomes empty, bleed the air from the master cylinder.
To avoid brake fluid from adhering, cover the painted surface with a shop rag or piece of cloth.

Using SST, disconnect the 2 brake lines from the master cylinder.
SST
09023-00101

Slowly depress the brake pedal and hold it (*1).

Cover the 2 outer holes with fingers, and release the brake pedal (*2).

Repeat (*1) and (*2) 3 or 4 times.

Using SST, connect the 2 brake lines to the master cylinder.
SST

Torque:
Without SST:
15 N*m{155 kgf*cm, 11 ft.*lbf}
With SST:
14 N*m{143 kgf*cm, 10 ft.*lbf}
NOTICE:
1. Use a torque wrench with a fulcrum length of 250 mm (9.84 in.).
2. This torque value is effective when SST is parallel to a torque wrench.

3. BLEED BRAKE LINE

NOTICE:

Bleed the air from the brake line of the wheel farthest from the master cylinder.

Connect a vinyl tube to the bleeder plug.

Depress the brake pedal several times, then loosen the bleeder plug with the pedal depressed (*3).

When fluid stops coming out, tighten the bleeder plug, then release the brake pedal (*4).

Repeat (*3) and (*4) until all the air in the fluid is completely bled out.

Tighten the bleeder plug completely.
Torque:
8.0 N*m{82 kgf*cm, 71 in.*lbf}

Repeat the above procedure for each wheel to bleed the air from the brake line.

4. BLEED BRAKE ACTUATOR ASSEMBLY (w/ VSC)

NOTICE:

After bleeding the air from the brake system, if the height or feel of the brake pedal cannot be obtained, bleed the air from the brake actuator assembly with the intelligent tester by following the procedure below.

Depress the brake pedal more than 20 times with the ignition switch off.

Connect the intelligent tester to the DLC3, then turn the ignition switch on (IG).
NOTICE:
Do not start the engine.

Turn the intelligent tester on and select "AIR BLEEDING" on the screen.
NOTICE:
1. Refer to the intelligent tester operator's manual for further details.
2. Bleed the air by following the steps displayed on the intelligent tester.

Bleed the air according to "Step 1: Increase" on the intelligent tester display.
NOTICE:
Make sure that the master cylinder reservoir tank does not become empty of brake fluid.
1. Connect a vinyl tube to either one of the bleeder plugs.
2. Depress the brake pedal several times, then loosen the bleeder plug connected to the vinyl tube with the pedal depressed (*5).
3. When fluid stops coming out, tighten the bleeder plug, then release the brake pedal (*6).
4. Repeat (*5) and (*6) until all the air in the fluid is completely bled out.
5. Tighten the bleeder plug completely.
  Torque:
  8.0 N*m{82 kgf*cm, 71 in.*lbf}
6. Repeat the above procedure for the rest of the wheels to bleed the air from the brake line.

Bleed the air from the suction line according to "Step 2: Inhalation" on the intelligent tester display.
NOTICE:
1. Bleed the suction line by following the steps displayed on the intelligent tester.
2. Make sure that the master cylinder reservoir tank does not become empty of brake fluid.
1. Connect a vinyl tube to the bleeder plug at the right front wheel or the right rear wheel and loosen the bleeder plug.
2. Operate the brake actuator assembly to bleed the air using the intelligent tester (*7).
  NOTICE:
  1. The operation stops automatically in 4 seconds.
  2. At this time, be sure to release the brake pedal.
3. Check that the operation has stopped by referring to the intelligent tester display and tighten the bleeder plug (*8).
4. Repeat (*7) and (*8) until all the air in the fluid is completely bled out.
5. Tighten the bleeder plug completely.
  Torque:
  8.0 N*m{82 kgf*cm, 71 in.*lbf}
6. For the rest of the wheels, bleed the air in the same way as stated in the above procedure.

Bleed the air from the pressure reduction line according to "Step 3: Decrease" on the intelligent tester display.
NOTICE:
1. Bleed the pressure reduction line by following the steps displayed on the intelligent tester.
2. Make sure that the master cylinder reservoir tank does not become empty of brake fluid.
1. Connect a vinyl tube to either one of the bleeder plugs.
2. Loosen the bleeder plug (*9).
3. Using the intelligent tester, operate the brake actuator assembly, completely depress the brake pedal, and hold it.
  NOTICE:
  1. The operation stops automatically in 4 seconds. When performing this procedure continuously, an interval of at least 20 seconds is required.
  2. When the operation is completed, the brake pedal goes down slightly. This is a normal phenomenon when the solenoid opens.
  3. During this procedure, the pedal seems heavy, but completely depress it so that the brake fluid comes out from the bleeder plug.
  4. Be sure to keep the brake pedal depressed. Never depress and release the pedal repeatedly.
4. Tighten the bleeder plug, then release the brake pedal (*10).
5. Repeat steps (*9) to (*10) until all the air in the fluid is completely bled out.
6. Tighten the bleeder plug completely.
  Torque:
  8.0 N*m{82 kgf*cm, 71 in.*lbf}
7. Repeat the above procedures for the rest of the brakes to bleed the air from the brake line.

Bleed the air from the brake line again according to "Step 4: Increase" on the intelligent tester display.
NOTICE:
1. Bleed the air by following the steps displayed on the intelligent tester.
2. Make sure that the master cylinder reservoir tank does not become empty of brake fluid.
1. Connect a vinyl tube to either one of the bleeder plugs.
2. Depress the brake pedal several times, then loosen the bleeder plug connected to the vinyl tube with the pedal depressed (*11).
3. When fluid stops coming out, tighten the bleeder plug, then release the brake pedal (*12).
4. Repeat (*11) and (*12) until all the air in the fluid is completely bled out.
5. Tighten the bleeder plug completely.
  Torque:
  8.0 N*m{82 kgf*cm, 71 in.*lbf}
6. Repeat the above procedures for each brake to bleed the air from the brake line.

Finish "AIR BLEEDING" on the intelligent tester and turn off the tester.

Disconnect the intelligent tester from the DLC3.

Turn the ignition switch off.

5. INSPECT FLUID LEVEL IN RESERVOIR

Check the fluid level and add fluid if necessary.
Fluid:
SAE J1703 or FMVSS No. 116 DOT3
If fluid leaks, tighten or replace the leaking part.
