This is because it is exposed to the most heat. The calipers have to be compressed to make room for the wider new pads. If you do not open the bleed screw while doing this, the old, oxidized fluid and any rust will be forced back into the brake lines. Opening the bleed allows this old fluid to escape.
How do you Bleed an anti lock braking system?
This system can also be bled using a bi-directional scan tool. The process is usually called the “system function test.” This process opens the valves and cycles the pump to purge air from the hidden areas of the modulator and should be run three times to make sure all air is removed.
