When you say you have released the pressure is this from all 4 wheel cylinders or from the master cylinder? Just a thought as I have suffered the same problem with my own repairs, not a C15A but never the less have suffered the same problem.

I agree with Dave it seems that the master cylinder is not allowing the fluid to return.
