Yes I changed the pedal. I'm going to bleed the master cylinder again. Maybe there is still air in there. I assume that would cause the pedal to not rebound

Before going that far, pull the soring and make sure it isnt binding...

Ok so I assume when I push the brake and the spring compresses there should be a pushrod to actuate the master cylinder right?? If so then I don't have a pushrod in there. I'm uploading a video now
