It doesn't happen all the time when I drive, but usually kicks in within 15 mins of operating my vehicle. I drive a 2002 Ford Escape. When I turn the radio off I can hear a hissing noise coming from underneath the dash. It sounds like sssssss.... When I tap on the break it stops, so I assume it has to do with the breaking system. No break lights have come on yet. Should I take the car into Ford to find out what the problem is?

the noise is from the brake booster/vacuum assist. The noise is the atmospheric pressure bleeding into the brake booster. (power brakes) I suspect the brake pedal is not ajusted properly. Most vehicles use this method of power brakes. Get into any vehicle and listen for the noise. Most luxury cars muffle the sound, but economy vehicles don't. Pull up on the brake pedal with your toe behind the pedal... if my diagnostic is correct the noise should go away. The noise is normal when stepping on the brakes.

it may well be that on a damp day even as the pads are moist, they make that sound. yet that sound ought to subside quickly, if no longer then get your rotors checked or look on the pads. it may also be that the motor vehicle became hit on that aspect and some parts that contact the braking assembly are bent or placed on out faster because some thing is bent. you should desire that it is purely the pads, and get it checked quickly, as once the pads placed on out the rotors start up warping, and that is much better extreme priced to fix. damage pads ought to get replaced at an section save for as low as one hundred and fifteen an aspect incl. taxes. Rotors- virtually double that a lot. desire this facilitates.

Chances are you have a small leak in a vacuum line going to your power booster for your power brakes.
Have a mechanic look at it. It won't make your brakes stop working, but if you lose all vacuum, they will require alot of leg force to stop.

You have a brake power booster vacuum leak and left unfixed you will eventually loose all power assist to your brakes. So it needs checking out.

IT SOUNDS LIKE IT MIGHT BE THE MASTER CYLINDER. TO BE SURE I WOULD CALL FORD AND ASK THEIR OPINION OR ANY EXPERIENCED GARAGE.
