The front of the master cylinder goes through the front of the proportioning valve and then to the front brakes. The rear goes to the rear. I looked through your pictures until I found one that showed the brake lines and it looks to me like you have them flipped.

I also noticed that you mounted your CPP prop valve low on the firewall. I'm not sure why but if you would have used the bracket to mount it on the mc mounting bolt the lines would have fell in place. I used a slightly different booster and mc so I had to bend up a different rear mc to valve line than was supplied with the kit but the front lines were perfect as is.

Here's mine using a CPP prop valve.
