WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.

When removed the master cylinder assembly, bleed the master cylinder in the following procedure to make bleeding of the brake pipeline easier (When no brake fluid is in the master cylinder).

Fill the brake fluid reservoir with the brake fluid.
Depress and hold the brake pedal.
Another operator closes the master cylinder outlets with his fingers.
In this condition, release the brake pedal.
Repeat Steps 2 to 4 for 3 or 4 times to fill the master cylinder with the brake fluid.
