Car pulls under braking, what gives?

[cecoen]

Ok, here is the deal. Older Unique kit with the "Deal?" master cylinders. It has "DEAL" written on the brake pedal so not sure if it is the pedal manufacturer or the master cylinder manufacturer, could be the "girling" units?

Anyway, it has two seperate master cylinders, one for the front and one for the rear brakes. They have small round reseviors with one brake line for the front and one brake line for the rear(they split to the left and right sides closer to the wheels).

The calipers are brand new(MGB units) with new rotors and pads(cheap soft pads). I have bled the front and rear by pulling the balance bar off and doing them seperately. I have pushed over 1 quart of fluid through them but it still pulls to the left(same symptom that started this whole brake rebuild) although it does stop much better than before it is still pulling and it will only lock up the front left? Any ideas? The only old parts left are the master cylinder and the lines. The master cylinders have only one line leaving the unit so how the heck could it be the master cylinder supplying more pressure to one side?

I have driven the car with the new brakes pretty easily for a few miles to break them in before I tried standing on the brakes. Under light braking it seemed to stop fine with little or no pulling? Although I did notice a slight pulling in the same direction from the alignment being off a little.

The car also "nose dives" pretty badly under braking. How do I get more braking from the rear?
Could the car be nose diving enough under braking for bump steer to be the pulling problem? It has the orig. MG front end and is very soft.

A lot of info here, what are you guys thoughts? Thanks for all the support you guys gave me with the rear brake questions already and thanks in advance for the help here.
