BRAKE FLUID BLEEDING

CAUTION / NOTICE / HINT

Note

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.

Tech Tips

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.

BLEED BRAKE MASTER CYLINDER SUB-ASSEMBLY
Note
- 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 brake master cylinder sub-assembly to avoid any potential contamination of the brake system. Contamination, for example by dirt particles or mineral oil, could lead to functional brake problems.
Tech Tips

If the brake master cylinder sub-assembly is reinstalled or runs out of brake fluid, bleed the brake master cylinder sub-assembly.
1. Using a union nut wrench, disconnect the 2 brake lines from the brake master cylinder sub-assembly.
  Note
  
  Do not kink or damage the brake lines.
  
  Do not allow any foreign matter such as dirt or dust to enter the brake lines from the connecting parts.
2. Slowly depress the brake pedal and hold it.*1
3. Cover the 2 outer holes with fingers, and release the brake pedal.*2
4. Repeat steps *1 and *2, 3 or 4 times.
5. *a Torque Wrench Fulcrum Length
  
  Using a union nut wrench, connect the 2 brake lines to the brake master cylinder sub-assembly.
  
  Torque:
  
  Specified tightening torque
  
  19.5 N*m { 199 kgf*cm, 14 ft.*lbf }
  Note
  
  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.
  Tech Tips
  
  Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.

  When using a union nut wrench (fulcrum length of 20 mm (0.787 in.)) + torque wrench (fulcrum length of 162 mm (6.38 in.)):
  
  17.36 N*m (177 kgf*cm, 13 ft.*lbf)

BLEED BRAKE SYSTEM

CAUTION:

If air is bled without using the GTS, damage or accidents may result. Therefore, always use the GTS when bleeding air.
Note
- After bleeding the brake system, if the required brake pedal reserve distance cannot be obtained, perform air bleeding of the brake actuator assembly with the GTS by following the procedure below.
- To prevent brake fluid from damaging painted surfaces, cover any surrounding parts with a piece of cloth.
1. Depress the brake pedal more than 20 times with the engine switch off.
2. Connect the GTS to the DLC3.
3. Turn the engine switch on (IG) and turn the GTS on.
  
  Note
  
  Do not start the engine.
4. Enter the following menus: Chassis / ABS/VSC/TRC / Utility / Air Bleeding.
  
  Chassis > ABS/VSC/TRC > Utility

  Air Bleeding
5. Bleed the brake system by following the instructions on the GTS.
6. After air bleeding, tighten each bleeder plug.
  
  Torque:
  
  8.3 N*m { 85 kgf*cm, 73 in.*lbf }
7. Turn the GTS off then turn the engine switch off.
8. Disconnect the GTS from the DLC3.
