    I'm going to ask what might be a dumb question, but here goes: why are your rear wheel cylinders on the bottom of your backing plates?

    Because he mounted the wheel cylinders upside down too.

    Backing plates are upside down first because model a rear end. I’m not going into detail of that. If you done know google.

    Also they are Lincoln backing plates. I would have clocked the backing plate to miss the spring perch but unlike the ford backing plates you can’t.

    Third. SS327 . The wheel cylinders are positioned correctly. Bleeder at the top. This has been done many times on here guys. I don’t know how some are shocked at what is being done.

    You did adjust the top (bottom on your rear brakes) locating stud to optimize the shoe’s up-down positioning, right?

    Yes. As Boling bros stated in their instructions.

    I got a couple new residual valves. Changing out the rear one first because I’m thinking since I had to adjust the pedal rod pushing on the mc a tad it is not holding the 10psi pressure to rears.

    I did a few up and downs on my road and it stops better than before. So we’ll see
