BRAKE SYSTEM (OTHER) BRAKE FLUID BLEEDING
CAUTION / NOTICE / HINT
- NOTICE:
- ·
for Manual Transaxle:
Move the shift lever to neutral and apply the parking brake before bleeding the brakes.
·for Automatic Transaxle and CVT:
Move the shift lever to P and apply the parking brake before bleeding the brakes.
·Add brake fluid to keep the level between the MIN and MAX lines of the reservoir while bleeding the brakes.
·If brake fluid leaks onto any painted surface, immediately wash it off.
·Do not operate the brake actuator assembly while air is in the brake system or in the brake master cylinder sub-assembly. Doing so may cause air to enter the brake actuator assembly.
·If bleeding the brake actuator assembly is difficult due to air in the brake actuator assembly, replace it with a new one.
- 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.
PROCEDURE
55783B
1.REMOVE CENTER NO. 1 COWL TOP VENTILATOR LOUVER
2. FILL RESERVOIR WITH BRAKE FLUID
47201
3.BLEED BRAKE MASTER CYLINDER SUB-ASSEMBLY
- NOTICE:
- ·
To prevent brake fluid from damaging painted surfaces, cover any surrounding parts with a piece of cloth.
·Be sure to clean your hands before bleeding the master cylinder to avoid any potential contamination of the brake system. Contamination, for example by dirt particles or mineral oil, could lead to functional brake problems.
- HINT:
-
If the brake master cylinder sub-assembly is reinstalled or runs out of brake fluid, bleed the brake master cylinder sub-assembly.
Using a union nut wrench, disconnect the 2 brake lines from the brake master cylinder sub-assembly.
Slowly depress the brake pedal and hold it.*1
Cover the 2 outer holes with fingers and release the brake pedal.*2
Repeat steps *1 and *2, 3 or 4 times.
| *a | Torque Wrench Fulcrum Length |
| *b | Union Nut Wrench |
Using a union nut wrench, connect the 2 brake lines to the brake master cylinder sub-assembly.
- Torque:
- Specified tightening torque (w/o VSC) : 15.2 N*m (155 kgf*cm, 11 ft.*lbf)
- Specified tightening torque (w/ VSC) : 19.6 N*m (200 kgf*cm, 14 ft.*lbf)
- NOTICE:
- ·
Do not kink or damage the brake lines.
·Do not allow the brake lines to twist or interfere with other parts or the vehicle body during tightening.
·Do not allow any foreign matter such as dirt or dust to enter the brake lines from the connecting parts.
- HINT:
- ·
Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.

·When using a union nut wrench (fulcrum length of 22 mm (0.866 in.)) + torque wrench (fulcrum length of 162 mm (6.38 in.)):
w/o VSC: 13.38 N*m (136 kgf*cm, 10 ft.*lbf)
·When using a union nut wrench (fulcrum length of 20 mm (0.787 in.)) + torque wrench (fulcrum length of 162 mm (6.38 in.)):
w/ VSC: 17.45 N*m (178 kgf*cm, 13 ft.*lbf)
4.BLEED BRAKE LINE
44510
5.BLEED BRAKE ACTUATOR ASSEMBLY (w/ VSC)
- NOTICE:
- ·
After bleeding the brake system, if the required height or feel of the brake pedal cannot be obtained, perform air bleeding of the brake actuator assembly with the GTS by following the procedure below.
·Perform the procedure for each brake line system until "Air Bleeding is complete" is displayed on the GTS.
Depress the brake pedal more than 20 times with the ignition switch off.
Connect the GTS to the DLC3 and turn the ignition switch to ON.
- NOTICE:
-
Do not start the engine.
Turn the GTS on and enter the following menus: Chassis / ABS/VSC/TRC / Utility.
Bleed the front right/rear left brake line system.
Enter the menu "Air Bleeding" and bleed the brake actuator assembly by following the instructions on the GTS.
- Chassis > ABS/VSC/TRC > Utility
-
Tester Display Air Bleeding - 50005 105 125
| Instruction on the GTS | Bleeding Portion |
|---|---|
| Increase Line (1st) | All wheels |
| Increase Line (2nd and later) | Front right and rear left wheels |
| Decrease Line | Front right wheel |
- NOTICE:
-
Perform air bleeding for the front right/rear left brake line system until "Air Bleeding is complete" is displayed on the GTS.
Bleed the front left/rear right brake line system.
Enter the menu "Air Bleeding" and bleed the brake actuator assembly by following the instructions on the GTS.
- Chassis > ABS/VSC/TRC > Utility
-
Tester Display Air Bleeding - 50005 105 125
| Instruction on the GTS | Bleeding Portion |
|---|---|
| Increase Line (1st) | All wheels |
| Increase Line (2nd and later) | Front left and rear right wheels |
| Decrease Line | Front left wheel |
- NOTICE:
-
Perform air bleeding for the front left/rear right brake line system until "Air Bleeding is complete" is displayed on the GTS.
Perform the Bleed Brake Line procedure again.
- NOTICE:
-
Perform air bleeding for the brake line of each wheel to bleed the brake system completely.
After air bleeding, tighten each bleeder plug.
- Torque:
- Front Brake : 8.3 N*m (85 kgf*cm, 73 in.*lbf)
- Rear Brake : 11 N*m (112 kgf*cm, 8 ft.*lbf)
Turn the GTS off and turn the ignition switch off.
Disconnect the GTS from the DLC3.
