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.
When bleeding air, select the suitable procedure listed below.
| Replaced/Installed Item | Work Procedure |
|---|---|
| Flexible hose (front/rear) | Bleed brake line |
| Disc brake cylinder assembly (front/rear) | |
| Brake actuator assembly | Bleed brake system |
| Brake master cylinder sub-assembly | |
| Brake master cylinder reservoir assembly | |
| Brake booster assembly |
PROCEDURE
BLEED BRAKE LINE
Remove the brake master cylinder reservoir filler cap assembly.
Add brake fluid to keep the level between the MIN and MAX lines of the reservoir while bleeding the brakes.
| Brake Fluid |
|---|
| SAE J1703 or FMVSS No. 116 DOT3 |
| SAE J1704 or FMVSS No. 116 DOT4 |
Note
Make sure that there is sufficient brake fluid in the reservoir.
Do not remove the filter from the brake master cylinder reservoir assembly and be sure to fill the brake master cylinder reservoir assembly with new brake fluid to avoid any potential contamination of the brake system. Contamination, for example by dirt particles or mineral oil, could lead to functional brake problems.
Loosen the bleeder plug of the front disc brake cylinder assembly RH.
Repeatedly depress the brake pedal and bleed the air from the bleeder plug of the front disc brake cylinder assembly RH.
Note
Add brake fluid to keep the level between the MIN and MAX lines of the reservoir while bleeding the brake lines.
After all the air in the brake fluid is completely bled out, tighten the bleeder plug while depressing the brake pedal.
Bleed the air from the bleeder plug of the front disc brake cylinder assembly LH using the same procedure as for the RH side.
Loosen the bleeder plug of the rear disc brake cylinder assembly RH.
Repeatedly depress the brake pedal and bleed the air from the bleeder plug of the rear disc brake cylinder assembly RH.
Note
Add brake fluid to keep the level between the MIN and MAX lines of the reservoir while bleeding the brake lines.
After all the air in the brake fluid is completely bled out, tighten the bleeder plug while depressing the brake pedal.
Bleed the air from the bleeder plug of the rear disc brake cylinder assembly LH using the same procedure as for the RH side.
Inspect for brake fluid leaks.
Inspect the brake fluid level in the reservoir.
Install the brake master cylinder reservoir filler cap assembly.
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
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.

Note
Make sure that there is sufficient brake fluid in the reservoir.
Do not remove the filter from the brake master cylinder reservoir and be sure to fill the brake master cylinder reservoir with new brake fluid to avoid any potential contamination of the brake system. Contamination, for example by dirt particles or mineral oil, could lead to functional brake problems.
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.
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.
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.)):
