Brake Bleeding: Service and Repair
BRAKE FLUIDBLEEDING
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 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.
^ To avoid brake fluid from adhering, cover the painted surface with cloth.
a. Disconnect the 2 brake lines from the master cylinder.

b. Slowly depress the brake pedal and hold it.
c. Cover the 2 outer holes with fingers, and release the brake pedal.
d. Repeat (b) and (c) 3 or 4 times.
e. Connect the brake lines to the master cylinder.

Torque: 15 Nm (155 kgf-cm, 11 ft. lbs.)
3. BLEED BRAKE LINE
NOTICE: Bleed the air from the wheel farthest from the master cylinder.
a. Connect the vinyl tube to 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.
d. Repeat (b) and (c) until all the air in the fluid is completely bled out.
e. Tighten the bleeder plug completely.
Torque: 11 Nm (110 kgf-cm, 8 ft. lbs.)
f. Repeat the above procedures for each wheel to bleed the air out of the brake line.
4. BLEED ABS & TRACTION ACTUATOR ASSEMBLY
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 ABS & TRACTION actuator assembly with a hand-held tester by following the procedures.
a. Depress the brake pedal more than 20 times with the ignition switch off.
b. Connect the hand-held tester to the DLC3, then turn the ignition switch to the ON position.
NOTICE: Do not start the engine.
c. Turn the hand-held tester power on and select "AIR BLEEDING" on the screen.
NOTICE:
^ Please refer to the hand-held tester operator's manual for further details.
^ Bleed the air by following the steps displayed on the hand-held tester.
d. Perform air bleeding according to "Step 1: Increase" on the hand-held tester display.
NOTICE: Make sure that 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 connected to the vinyl tube with the pedal depressed.
3. When fluid stops coming out, tighten the bleeder plug, then release the brake pedal.
4. Repeat (2) and (3) until all the air in the fluid is completely bled out.
5. Tighten the bleeder plug completely.
Torque: 11 Nm (110 kgf-cm, 8 ft. lbs.)
6. Repeat the above procedures for the rest of the wheels to bleed the air out of the brake line.
e. Bleed the air out of the suction line according to "Step 2: Inhalation" on the hand-held tester display.
NOTICE:
^ Bleed the air by following the steps displayed on the hand-held tester.
^ Make sure that 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 & TRACTION actuator assembly using the hand-held 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 has stopped, by referring to the hand-held tester display and tighten the bleeder plug.
4. Repeat (2) and (3) until all the air in the fluid is completely bled out.
5. Tighten the bleeder plug completely.
Torque: 11 Nm (110 kgf-cm, 8 ft. lbs.)
6. For the rest of the wheels, bleed the air in the same way as stated in the above procedures.
f. Bleed the air out of the pressure reduction line according to "Step 3: Decrease" on the hand-held tester display.
NOTICE:
^ Bleed the air by following the steps displayed on the hand-held tester.
^ Make sure that 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 & TRACTION actuator assembly using hand-held tester, completely depress the brake pedal and hold 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 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.
5. Repeat (2) to (4) until all the air in the fluid is completely bled out.
6. Tighten the bleeder plug completely.
Torque: 11 Nm (110 kgf-cm, 8 ft. lbs.)
7. Repeat the above procedures for the rest of the wheels to bleed the air out of the brake line.
g. Bleed the air out of the regular bleeding again according to "Step 4: Increase" on the hand-held tester display.
NOTICE:
^ Bleed the air by following the steps displayed on the hand-held tester.
^ Make sure that 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 connected to the vinyl tube with the pedal depressed.
3. When fluid stops coming out, tighten the bleeder plug, then release the brake pedal.
4. Repeat (2) and (3) until all the air in the fluid is completely bled out.
5. Tighten the bleeder plug completely.
Torque: 11 Nm (110 kgf-cm, 8 ft. lbs.)
6. Repeat the above procedures for each wheels to bleed the air out of the brake line.

h. Finish "AIR BLEEDING" on the hand-held tester and turn off the power.
i. Disconnect the hand-held tester from the DLC3.
j. Turn the ignition switch off.
5. CHECK FLUID LEVEL IN RESERVOIR
a. 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.
