BLEED BRAKE SYSTEM
CAUTION:
If air is bled without using the intelligent tester, damage or accidents may result. Therefore, always use the intelligent tester when bleeding air.
Turn the ignition switch to ON.
Remove the brake master cylinder reservoir filler cap assembly.
Add brake fluid until the fluid level is between the MIN and MAX lines of the reservoir.
Repeatedly depress the brake pedal and bleed air from the bleeder plug of the front disc brake cylinder RH.
Repeat the step above until the air is completely bled, and then tighten the bleeder plug while depressing the brake pedal.
Bleed the air from the bleeder plug of the front disc brake cylinder LH using the same procedure as for the RH side.
With the brake pedal depressed, loosen the bleeder plug of the rear disc brake cylinder RH, continue to hold the brake pedal and allow brake fluid to be drained from the bleeder plug while the pump motor operates.
Tech Tips
Air is bled as the pump motor operates while the brake pedal is being depressed.
Be sure to release the brake pedal to stop the motor after approximately 100 seconds of continuous operation.
As brake fluid is continuously drained while the pump operates, it is not necessary to repeatedly depress the brake pedal.
When there is no more air in the brake fluid, tighten the bleeder plug, and then release the brake pedal.
Bleed the air from the bleeder plug of the rear disc brake cylinder LH using the same procedure as for the RH side.
Turn the ignition switch off and connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the intelligent tester on.
Enter the following menus: Chassis / ABS/VSC/TRC / Utility / Air Bleeding.
Note
To protect the solenoid from overheating, the solenoid operation stops automatically in 4 seconds, and then the solenoid will not respond to commands for an additional 20 seconds.
Repeatedly depress the brake pedal several times, and then, with the brake pedal depressed, turn FR on and bleed air.
Tech Tips
Air returns to the brake master cylinder reservoir together with the brake fluid and is bled from the brake system.
Note
As it is not possible to visually confirm that air is being bled, repeat this step 10 times.
Do not loosen the bleeder plug.
Turn FL on and bleed air using the same procedures as for FR.
Turn RR on, loosen the bleeder plug of the rear disc brake cylinder RH and drain brake fluid.
Tech Tips
Do not depress the brake pedal.
As brake fluid is automatically drained while the pump and solenoid operate, it is not necessary to operate the brake pedal.
Repeat the step above until the air is completely bled, and then tighten the bleeder plug.
Turn FL Line on and bleed the air from the bleeder plug of the front disc brake cylinder LH using the same procedure as for the RH side.
Turn RR Line on and loosen the bleeder plug of the rear disc brake cylinder RH.
Tech Tips
Be sure to bleed air with the brake pedal depressed.
Repeat the step above until the air is completely bled, and then tighten the bleeder plug.
Turn RL Line on and bleed air from the bleeder plug of the rear disc brake cylinder LH using the same procedure as for the RH side.
Turn the intelligent tester off and turn the ignition switch off.

CHECK BRAKE PEDAL HEIGHT
Check the brake pedal height.
| Standard Pedal Height from No. 2 Dash Panel Insulator Pad |
|---|
| 147.1 to 157.1 mm (5.80 to 6.18 in.) |
Note
Do not adjust the pedal height. Doing so by changing the push rod length will structurally change the pedal ratio.
If the pedal height is incorrect, adjust the rod operating adapter length.
Adjust the rod operating adapter length.
Remove the clip and clevis pin.
Loosen the clevis lock nut.
Adjust the rod operating adapter length by turning the pedal push rod clevis.
| Standard Rod Operating Adapter Length "A" |
|---|
| 201.7 to 202.7 mm (7.94 to 7.98 in.) |
Tighten the clevis lock nut.
Set the master cylinder push rod clevis in place, insert the push rod pin from the outside of the vehicle and then install a new clip.
If the pedal height is incorrect even if the rod operating adapter is adjusted, check that there is no damage to the brake pedal, brake pedal lever, brake pedal support and dash panel.
Even if there is damage, there is no problem if the reserve distance is within the standard value.
If necessary, replace any damaged parts.
CHECK PEDAL FREE PLAY
Push in the pedal until resistance is felt. Measure the free play as shown in the illustration.
| Standard Pedal Free Play |
|---|
| 1 to 6 mm (0.0394 to 0.236 in.) |
CHECK PEDAL RESERVE DISTANCE
Release the parking brake lever. With the engine running, depress the pedal and measure the pedal reserve distance as shown in the illustration.
| Standard Pedal Reserve Distance from No. 2 Dash Panel Insulator Pad at 490 N (50 kgf, 110.2 lbf) |
|---|
| More than 67 mm (2.64 in.) |
If incorrect, troubleshoot the brake system.
