Brake Bleeding: Service and Repair

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 out of the brake system.

NOTICE: Wash the brake fluid off immediately if it adheres to any painted surfaces.

1. FILL RESERVOIR WITH BRAKE FLUID
Fluid: SAE J1703 or FMVSS No. 116 DOT3
2. BLEED MASTER CYLINDER

HINT: If the master cylinder has been disassembled or if the reservoir becomes empty, bleed the air out of the master cylinder.

a. Disconnect the brake lines from the master cylinder.
SST 09023-00101
b. Slowly depress and hold the brake pedal.

c. Cover off the outer holes with your fingers, and release the brake pedal.
d. Using SST, Repeat (b) and (c) 3 or 4 times.
e. Connect the brake lines from the master cylinder.
SST 09023-00101
Torque: 15 Nm (155 kgf-cm, 11 ft. lbs.)

3. BLEED BRAKE LINE
a. Connect the vinyl tube to either one of the bleeder plug.
b. Depress the brake pedal several times, then loosen the bleeder plug with the pedal depressed.
c. When fluid stops coming out, tighten the bleeder plug then release the brake pedal.
Torque: 8.3 Nm (85 kgf-cm, 73 inch lbs.)
d. Repeat (b) and (c) until all the air in the fluid is completely bled out.
e. Repeat the above procedure to bleed the air out of the brake line for each wheel.
4. BLEED BRAKE ACTUATOR

NOTICE: After performing the usual air bleeding in the brake system, if the height or feel of the brake pedal cannot be obtained, perform air bleeding in the VSC actuator assembly with the hand-held tester by following the procedures.

a. Depress the brake pedal more than 20 times with the engine off.

b. Connect the hand-held tester to the DLC3, then turn the ignition switch ON.

NOTICE: Do not start the engine.

c. Select "AIR BLEEDING" on the hand-held tester.

HINT: Please refer to the Hand-Held Tester Operator's Manual for further details.

d. Bleed out the air out of the reqlal brake line in "Step1: Increase" on the hand-held tester display.

NOTICE:
^ Perform the air bleeding by following the steps displayed on the hand-held tester.
^ Make sure that the brake fluid in the master cylinder reservoir tank does not become empty.

1. Connect the vinyl tube to either one of the bleeder plugs.

2. Depress the brake pedal several times, then loosen the bleeder plug of one of the above wheels with the pedal depressed.
3. When fluid stops coming out, tighten the bleeder plug, then release the brake pedal.
Torque: 8.3 Nm (85 kgf-cm, 73 inch lbs.)
4. Repeat (2) and (3) until all the air in the fluid is completely bled out.
5. Repeat the above procedure to bleed the air out of the brake line for each wheel.
e. Bleed the air out of the suction line in "Step 2: Inhalation" on the hand-held tester display.

NOTICE:
^ Perform the air bleeding by following the steps displayed on the hand-held tester.
^ Be careful that the brake fluid in the master cylinder reservoir tank does not become empty.

1. Connect the vinyl tube to the bleeder plug at the right front wheel or the right rear wheel and loosen the bleeder plug.
2. Operate the ABS actuator assembly using the handheld tester to bleed the air.

NOTICE:
^ The operation stops automatically in 4 seconds.
^ At this time, be sure to release the brake pedal.

3. Check that the operation stops by using the screen of the hand-held tester.
4. Repeat (2) and (3) until all the air in the fluid is completely bled out.
Torque: 8.3 Nm (85 kgf-cm, 73 inch lbs.)
5. For the rest of the wheels, bleed the air in the same way as stated in the above procedure.
f. Bleed the air out of the pressure reduction line in "Step 3: Decrease" on the hand-held tester display.

NOTICE:
^ Perform the air bleeding by following the steps displayed on the hand-held tester.
^ Make sure that the brake fluid in the master cylinder reservoir tank does not become empty.

1. Connect a vinyl tube to either one of the bleeder plugs.
2. Loosen the bleeder plug.
3. Using the hand-held tester operate the ABS actuator assembly using hand-held tester, completely depress the brake pedal and keep depressing it.

NOTICE:
^ The operation stops automatically in 4 seconds. When performing this procedure continuously, an interval of at least 20 seconds is required.
^ When the operation is completed, the brake pedal slightly goes down. This is a normal phenomenon caused when the solenoid opens.
^ During this procedure, the pedal seems heavy, but completely depress it so that the brake fluid comes out from the bleeder plug.
^ Be sure to keep depressing the brake pedal. Never depress and release the pedal repeatedly.

4. Tighten the bleeder plug, then release the brake pedal.
Torque: 8.3 Nm (85 kgf-cm, 73 inch lbs.)
5. Repeat (2) to (4) until all the air in the fluid is completely bled out.
6. Repeat the above procedure to bleed the air out of the brake line for each wheel.
g. Bleed the air out of the requiar brake line again in "Step 4: Increase" on the hand-held tester display.

NOTICE:
^ Perform air bleeding by following the steps displayed on the hand-held tester.
^ Make sure that the brake fluid in the master cylinder reservoir tank does not become empty.

1. Connect the vinyl tube to either one of the bleeder plugs.

5. CHECK FLUID LEVEL IN RESERVOIR
a. Check the fluid level and add fluid, if necessary.
Fluid: SAE J1703 or FMVSS No. 116 DOT 3
