No Power. Brake pedal hard to push.

Hello,

My brake pedal is hard to push and a hissing sound is coming from underneath the instrument panel. The car stops as good as it always has, but you have to use your leg muscle to do so. Folks have been suggesting a faulty power booster.

Any ideas and solutions appreciated.

Thanks,

Those folks are more than likely correct. As it would seem that you are lacking the assist that the brake booster offers. Probably a leak in the diaphram of one of the other internal sealing surfaces. The hissing leads me to believe the sealing surface between firewall side of the booster and the firewall "connecting" area is in question as well as possibly the diaphram.

I would look into replacing the booster.
