if you could completely disconnect the front brakes and apply full braking with just the rear,
would the weight transfer still happen, i know that if i apply the park brake only in a straight line, the rear squats, now is the weight still being transfered to the front or to a point infront of the rear wheels?
As has been said, yes it will transfer *but* as you transfer weight off of the rear, you have less grip, which means less available braking. The amount the brakes can decelerate the vehicle will be significantly low.

my locost has the brake bias bar biased to the rear because it has 40-60 weight distribution, and it stops better like that than with no bias, the acid test is on a dirt road, which end consistantly locks up under hard braking? i will almost gaurentee that on most cars the fronts lock up, this to me indicates that when the fronts lock, the backs still have more to give that is not being used, i do understand that on a dirt road the tires break away before weight transfer can occur.

all of you that race, i have a question,"which tires are more prone to flat spotting, the fronts or the backs?"
The fronts tend to lock more since the bias is typically in that direction. If a car is 40/60 weight distribution, you probably won't want 60% of your braking effort on the rear since it loses weight as the brake pedal is applied. Many factors effect how much weight transfers forward under braking but lets say you have 20%; in this case you want 60% of your braking to come from the front wheels since they have the extra weight.
