I don’t remember this issue when I drove it home but I’ve noticed recently that when my 01 gt is idling the brake pedal goes to the floor with little resistance. It’ll still stop no problem it’s just that you have to push it so far. While driving if I were to panic stop it stops no problem. I’ll confirm again but while it’s off if I pump the pedal it will get hard but still has a lot of travel. I’m thinking maybe master cylinder? Any brake experts on here?
