The pedal goes all the way to the floor and my wife is afraid to drive it. I have been changing my own brake pads and shoes for many years on many vehicles and have never had this before. I am not sure if it is the booster or the master cylinder, or if I screwed up the reinstallation of the calipers. Does anyone know how to check these things. The booster looks like a real pain in the A to get to and I think it may have sprung a vacuum leak or something when I squeezed the caliper piston in to accommodate the new pads. Help Please???
I replaced front brake pads, and now hear a hissing sound behind the pedal. on 1999 Chrysler Sebring

agree with pushrod also check your master cylinder cap/cover maybe not close/tight enough.

Unless the rod that goes through the brake booster is broken in half, the booster CAN NOT cause the pedal to go to the floor!! I don't care what you have been or will be told! Recheck the work you did, there is a problem there. Once that is fixed, so should your brake system be! Did you open any bleeder screws or any lines etc?
