The reason I asked is that the problem described doesn't add up to the m/c being too small. He said he "had to stand on the brakes" to get it to slow down, not that the pedal went to the floor. A smaller bore m/c will make more pressure, but at a lower volume. The bigger bore makes more volume, but as result, the pressure will be lower. It's just like gear reduction, only using fluid.
