thing is brakes just dont seem to have any pressure this i think is due to air coming out of servo to master cyl join.as everytime press peddle down it just go all way down now while you can here air coming out of join its deff got to be this but it just dont look right as where its coming from looks like its meant to let air out ????? right anoying as its prob some thing stupid
