brakes

how can you tell if a brake booster is bad

Vacuum leak causes extremely stiff pedal, and hissing sound under dash whenever brake pedal is pushed....has been my experiences..

the problem is i have only about 2inches of pedel from the floor. i have good brakes just not a full pedel, and yes i bled all the lines. and the mastercylnder
was replaced about a year ago. and there are no leaks.
