just rebuilt my master and could not get it to pump. It is together properly ,but it appears the plunger does not return past the fill hole, hence no fluid able to inter bore. it only enters the bore between the 2 plungers so it can't go anywhere. In a prior post a guy said he drilled out the other hole and it worked. because that hole is in front of the plunger it makes sense, but it did not come that way from the factory so it can't be right. why is that 1/2 drilled hole there to begin with? I know I could just buy a new one and be done, however I would like to solve this mystery. stumped
