I have no rear brakes at all. good master cycinder. can not get fluid to rear.need ideas

It sounds like you have a stuck ABS pump that will not allow the fluid to move from the master cylinder to the rear. I would take it to a garage where a technician can use a scan tool to diagnose the problem. ABS is quite complicated so you are better off leaving it to the pros.

GTP Dad is right, you definitly have a brake fluid issue to the rear wheels. Have you tried setting the parking brake to see if the rear brake assemblies are operating? If they work then you know that you have a hydraulic problem to the rear. That is one for the Pro's, You don't want to mess with the ABS system if you dont know what you are doing. It is too easy to foul things up. ( I'm not questioning your abilities) but like GTPDad says it's a complicated system.

Good luck
