my brake booster went out and my brakes are hard as heck to press and they make an airy noiise when you push them down on top of that and i was told this is why my engine runs weird sometimes. the vacuum line is hooked up, but the booster is bad, ihave another booster from a GTA i dont know how to take my old one off and put my new one on though i dont have much money so could anyone help me? its a 86 trans am 4 wheel disc brake car

 

you have to unbolt it from inside behind the dash IMO its easier to take out the drivers seat and lay on your back get a extension with a ujoint on it and have at it. its a PITA
