No brake fluid to back brakes, could not bleed rear brakes? Fluid at master cylinder, none at line junction over differential. Guess I crack every connection from front to back until I find stoppage.

Hi and thanks for using 2CarPros. Com.

Chances are, there is no blockage in the steel lines unless one was bent or pinched shut. If there is no pressure, there is a good chance the master cylinder (MC) is bad. In the MC, there are two plungers (or pistons) which distribute fluid. One is for the front and the other is for the rear. If there is no pressure, disconnect the lines at the MC and see if both ports produce pressure. I have a feeling the rear one will not.

Let me know what you find or if you have other questions.

Take care,
Joe

They both put out pressure. There are three places the went flex/rubber, I will see is I get fluid past those. I have had cases of collapsed rubber/flexed brake lines in other vehicles.
Thanks

Let me know. And yes, the rubber hoses can collapse inside and cause this type of issue.
