bad braking after adjustable proportioning valve => HELP!

[night_rider_692004]

Hello!

It's a little bit difficult to describe for me on english, but I will try.

I own a 69' Camaro with original front disc brakes and rear drum brakes. No proportioning valve for the drums (why?).

My new setup:



I installed one ajustable proprtioning valve for the front disc and aone for the rear drums, because i want to install discs at the rear next year.
I didn't install the metering valve (the valve in the lines for the FRONT brakes) and the pressure differnetial warning any more.
New situation:
I have no "hard point for braking" when I depress the brake pedal. It is soft for a way of 2", then there's a pressure built up, but a poor braking performance.

From a speed of approx 30 mph the front brakes not lock up.

First question: Is this setup ok or should I have to install the other valves again?

One more problem:

On the left front side the bleeding screw at the brake caliber is broken.

So I have to deinstall the caliber, loosen the brake hose for bleeding. This is not a very good way but I don't know something better. Ok, installing a new one will be the best. Perhaps there's still air in the front lines.

I will try to do a better bleeding, but I also want to know if the technical setup => One adjustable proportioning valve for thr front and one for the rear without any others should work!

Which MC are you using? If you are using a disk/drum MC? You shouldn't need a adj prop valve for the front disks if you are using a disk type MC. If you removed the factory prop valve and distrobution block, you need the adj prop valve for the rears (so they don't lock up before the rears). Can you post any pictures and info of your set up.
