    Combination/proportioning valve for 73 LaSabre!!??

    The combo valve is not letting me properly bleed brakes. Any way to unstick valve, or does anyone have a replacement?

    You can try opening up a bleeder on the front and back at the same time.

    Or there's this (I believe you have a normal GM prop valve with a warning light switch):

    If it still gives you trouble I would replace it
