So when I was replacing the struts on my 05 Chevy cobalt ls we noticed the brake line on the passenger side was leaking then when they replaced it, they also notice that the master cylinder was leaking and they also replaced the wheel cylinders in the rear, they have bleed the brakes and did abs bleed numerous times through out 4 weeks and my car stops when the pedal is almost to the floor and I’m out of ideas of what could cause this problem
