I've got a problem w/my brakes. I'm not w/my car right now, but my friend has been driving it during thanksgiving weekend and he said as he was exiting the hwy and tried braking like normal, there was no pressure in the pedal until he pressed it all the way down. as he kept driving, the pressure came back slowly .. and it's back to normal now. does anyone know what could have caused this? I just installed my cai before i left for the weekend and i noticed a loose vacuum hose of some sort dangling in the engine bay, but it appeared to be attached to nothing (just got it back from the shop that way).
