A little additional info: I just relaced both front calipers and brake hoses yesterday as well as new brake pads. It appeared to brake ok for a short time just after the job. Today I took it for a drive and and it's still pulling left and the left front brake is sqealing. When I got home I jacked it up and sure enough the Left front was dragging much more than the right. I'm kinda leaning towards the master cylinder as well. Is their any way to check the master cylinder or do you just have to replace it?
Thanks Ed
