My Ford Explorer has a problem with the brakes, when you press the brake
peddle to the floor, it will make a whisssh sound. When you are trying to
stop, it doesn't grab until the peddle goes all the way down to the floor,
would you think the sound would be coming from the master cylinder or the
power booster? Can some one bleed the brakes by hand if the system has rear
anti lock or does this have to be done by a mechanic shop?

Thank you, ask if there isn't enough information given here.

They told me that the master cylinder needs to be replaced because it is
leaking, but I was wondering if there was more to it than the master
cylinder that is causing that whisssh sound.

That sound is noemal for a brake booster being operated through it's full range (due
to the bad master). When the brakes are operating normally you can hear it slightly if
you listen close.
