bleeding new wheel cylinders

Well I put the vacumn pump on the rear wheel cylinder bleeders and nothing, So I took Lou3500's advice and pulled the line loose after the distribution block at rear housing and nothing and then I took it apart before the rear hose and wa laa. Brake fluid, evidently the hose collapsed inside, at the rear housing distributuion block . It looked alright on the outside. I have a new one on the way, so i hope this will solve the problem. I will keep posted.
Thanks everyone for the help
