brake proportion question...
if your car(don't know what kinda car you got) is a 4th gen f-body the weight distribution is like 58-42, so if you set it @50/50 you're rear brakes are going to lock all the time.
it's also dependent on what brakes you got...I'm assuming you got aftermarket brakes due to you actually having a proportioning valve so that needs to be taken into consideration as well.
When we set up cars we start at a 90/10 or 80/20 bias and turn it up until there is lockup. The factory rears are hypersensitive and actually quite effective. At a lower bias it typically feels like the *** end wants to come around the front because it's trying to travel at a higher speed than the front - giving the car a loose feeling under braking. You'll need to really get some seat time and testing to dial it in and feel poised.
