by repeating steps 6 through 15.

Bleeding the Caliper
17. Bleed the air from each wheel in the order listed below:

Right rear wheel cylinder

Left rear wheel cylinder

Left front caliper
 Right front caliper
Conduct air bleeding from the wheels in the above order. I
f
no brake fluid comes out, it suggests that air is mixed in the
master cylinder. In this case, bleed air from the maste
