Brake issues

[Rgallop]

I changed front brakes on my 03 gt a few weeks ago, yesterday it seem like they were dragging. I jacked the car up and the brake seemed to be dragging. now when I stop I here a hissing type noise coming from under my hood. Brakes still work good noise is just weird. I need some Ideas. Thanks Ray

The noise is only there if I have the brakes pushed down,the harder I push the more noise. I need some help.

Check your power steering fluid. make sure it's not low

Yeah, I second that Rgallop. Might make no sence, but neither does an invention called hydroboost. Here is a recent threat I started, which may help you. Just for the hell of it, see if there's steering fluid pooling in that area I have circled (top circle, both pics).

I checked and the power steering and it is a little below the fill, topped it off noise went away. Did not find any leaks. Thanks Ray
