My brakes feel very mushy don't seem to be working well any ideas what could be wrong?

mushy or spongy feeling brakes are caused by a number of things...the most common is air in the lines or bad rubber lines between the calipers at the wheels and the hard lines...start by having your brake system bled to remove any air and have the rubber lines checked...any good repair shop should be able to do this fairly cheep. other causes could be a bad master cylinder or a small leak...but any of these could fail at any time so get it fixed asap to avoid having your brakes go out on you.
