When I press on the brake pedal in Drive or Reverse, I hear a hissing sound comming from behind the pedal, and it has become very stiff and hard to push.
When I do press on the brake, I hear the clicking sound under my center console which is releasing it to allow me to go out of park, but the brakes are weak and slows down slightly, whicle taking a while to stop.
The harder you press, the better it gets, but I had to use all my weight to stop.
All levels are good, brakes are good, haven't had this problem before in any other vehicle.
Any help would be appreciated, thanks.
