You need to bleed your brakes, a very common technique explained on the internet. Basically there is a bleed valve near the break, you pump the brake with the valve open, and you will lose some fluid but also flush any air out.
Start at the rear passenger side, then rear drivers, then front passenger, then drivers side brakes, bleed one at time, very helpful to have someone to help you with this
