What does it mean when the brake light comes on in your grand marquis leaking fluid now and you have to push all down brake?

When the brake light comes on in your Grand Marquis and you have to push down all the way to brake, it means that the brake fluid level is low. Brake fluid is essential for the proper functioning of your car's braking system, as it helps to transmit the force from the brake pedal to the brake calipers. If the brake fluid level is low, it can cause the brakes to become spongy or unresponsive, and can even lead to complete brake failure.

There are a few reasons why the brake fluid level might be low, including:

* Leaks: Brake fluid can leak from a variety of places in the braking system, including the brake lines, calipers, and master cylinder.

* Evaporation: Brake fluid can also evaporate over time, especially if the vehicle is not driven very often.

* Wear: The brake pads and rotors can wear down over time, which can cause the brake fluid level to drop.

It's important to have the brake fluid level checked regularly, and to add brake fluid if necessary. You should also have the brakes inspected regularly to check for any leaks or other problems.

If you notice that the brake light is on in your Grand Marquis, and you have to push down all the way to brake, it's important to have the brake fluid level checked and the brakes inspected as soon as possible.
