Hey all, I have a 1990 St that I have swapped to 5 lug and disc brakes in the rear. The front is still 4 lug and stock brakes right now. Will I be able to bleed the brakes and have a pedal without getting a proportioning valve? If not, which car would have a proportioning valve that would work? My st is non abs and the donor car was a 93 vert with abs. I also still have the stock 90 st master cylinder in the car. I got fluid to all calipers, but my pedal was still not working properly. Any help would be greatly appreciated.
