Matt sounds like air in the brake system. Check all the wheel cylinders for
leaks. If leaks then rebuild, else have hydrolic system power bled (forcing
fluid in under pressure gets out bubbles that boyancy tends to leve in).
Adjust rear brakes. Your brakes should be hard & high. If the problem returns
and there is still no sign of leakage at the wheeels your master cylinder is
leaking. Replace & get another power bleed.
