Why do I have to push my brake pedal so far?
One of the main reasons why your brake pedal may become soft is because you have air in your brake lines. Air does not provide any force that helps your brakes stop. As such, when air is in your brake lines, your brake pedal can be pushed all the way down to the ground due to the lack of force.

What does it mean when your brake pedal is low?
