OK, I'm going to kind of get off the subject here. I have done the convert from drum to disc brakes on the rear of my 96 Impreza Brighton. Cake! Now I foud that the braking is disperportionate front to rear, the fronts lock up, and the rears seem to have very limited aply. I was woundering if any on has done this mod and changed there proportioning valve with some sucsess in this area. I would like to use a proportioning valve from another Subaru if at all posable. If someone could help out with some info I would appreciate it. Thanks.
