Connect a vinyl tube to the bleeder plugs.

Depress the pedal several times, and then loosen the bleeder plug with the pedal depressed.

When fluid stops coming out, immediately tighten the bleeder plug. Then release the pedal.

Repeat the 2 previous steps until all the air in the brake fluid is gone.

Tighten the bleeder plug.

Torque:

for front brake:

11 N*m{110 kgf*cm, 8 ft.*lbf}

for rear brake:

10 N*m{102 kgf*cm, 7 ft.*lbf}

Install the cap.

Bleed air from the brake line for each wheel by repeating the above procedures.

Remove the bleeder plug cap.

Connect the vinyl tube to the bleeder plug.

Depress the clutch pedal several times, and then loosen the bleeder plug with the pedal depressed.

At the point when fluid stops coming out, tighten the bleeder plug, and then release the clutch pedal.

Repeat the previous 2 steps until all the air in the fluid is completely bled out.

Tighten the bleeder plug.

Torque:

11 N*m{112 kgf*cm, 8 ft.*lbf}

Install the bleeder plug cap.

Check that all the air has been bled out of the clutch line.

Check the fluid level.
If the brake fluid level is lower than the MIN line, check for leaks and inspect the disc brake pads. If necessary, refill the reservoir with brake fluid to the MAX line after repair or replacement.

Fluid:

SAE J1703 or FMVSS No. 116 DOT3

for vehicles with SRS:
Check SRS warning light (Toyota Fortuner RM000000XFD0EGX.html).
