Spongy brakes are when the pedal has a mushy feel to it that seems to go away after pressing it multiple times at once but comes back after laying off the pedal. This is a big problem when getting the vehicle to stop. Spongy brakes are a result of air getting into the brake system, which can happen from leaks in the lines, too little fluid in the system or the replacement of a part like a caliper that opened up a brake line. More than anything, you need to purge the air from the brake system with what is known as “bleeding the brakes.”

Step 1

Raise at least one end of the vehicle on jack stands and remove the wheels so that you can access the brakes.
