OK so, my brake pedal is super hard and the defroster is the only working vent i have, i havnt used the 4x4 yet so im not sure if it works or not. is my hydrobooster broken? is there a disconnected hose? whats going on.

thanks alot

 

Do you have hydroboost ? Sounds like a vacum leak, but that wouldn't affect the brakes if you have hydroboost.

 

i do have hydroboost, can i get it into 4x4 somehow quick?
