Pump the brake pedal 3 times and then hold
the pedal down to pressurize the system.
While holding the brake pedal down, open
the bleeder to release brake fluid. After fluid
is released, close the bleeder, and release
pressure from the brake pedal.
*IMPORTANT
DO NOT release the brake pedal until
after the bleeder screw is fully closed .
*NOTE
Bleeder screw tightening torque:
6.9-12.7 Nm (0.7-1.3 kgf.m, 5.1-9.4
lb-ft)
5.
Repeat step 4 until no air bubbles appear in
the fluid.
*NOTE
DO NOT allow the fluid level to drop
below the MIN line. If the level drops
below MIN at any time during this
procedure, it is required to start the
bleeding process over, starting from the
RIGHT REAR brake assembly.
6.
Refill the reservoir to the MAX line with
brake fluid.

then move to the inside bleeder (until no
air bubbles appear in the fluid).

Repeat steps 3-6 at the REAR LEFT
wheel, then the FRONT RIGHT wheel.

Reinstall all 4 wheels, remove the vehicle
from the lift, and verify proper brake
operation to complete the service brake line
air bleeding procedure.
