Just recently I noticed my brakes were squishy and they are never squishy so I decided to investigate. Brakes are brand new so thats not the problem. I noticed however that my brake resovoir was half full so I filled it up and replaced the cover and gasket( were messed up ). It was fine for a week and they got squishy again and the resovior was almost empty this time. there is no brake fluid on any of the brakes and no wet areas indicating that they are leaking. What is going on? I need to fix soon because it is annoying me.

Thanks Drew

 

got to be going someplace. look for wet spot along the lines, booster, and wheels, you might have to actually pull the wheels to get a good look.

 

Check all the hardlines as well as the flex hoses. Is this a slow leak or does it happen slowly.

 

Is you brake booster all rusty under where the master cylinder mounts to it? If so, it's MC time... catch it before the brake fluid ruins the booster too.
