Im with Brambose, instead of spending more money try bleeding the system again, if you exposed the master to air you should bleed that first and then the rest of the system. Remember to bleed the brakes starting with the wheel most furthest from the master then every wheel that falls in line relative to distance after that, i.e. RH rear wheel, LH rear wheel, RH front and finally LH front. If your car is true JDM all of this is reverse.
