Correct,

but his pictures are the correct way to do a break job.To avoid damage to the car,

also its best to bleed the breaks after doing it this way.
couple times per wheel will get any air that gets sucked into the system when it was opened.

Or you could fill the jar full of new fluid and make sure that tube is far down into it..that way it can not suck any air..do this if your doing it alone.
