So....back to the original question. Any idea the inside diameter of 1 port would be a different size than the other 2 - both sides of the rear t is also the same i.d . as the 1 odd ball on the front distribution valve.Really small nearest I come to with calipers is 1/16" others are 1/8". Could this be to insure the brake cylinders would work correctly?Fluid distribution ? I am pretty sure Mopar engineered it this way for a reason- does anyone have an answer?
